Gemini (constellation) Gemini (constellation) List of stars in Gemini Abbreviation: Stars known to have planets: 3 Visible at latitudes between +90° and −60° Best visible at 21:00 (9 p.m.) during the month of February Gemini ( Latin: twins, symbol , Unicode ♊) is one of the constellations of the zodiac known as "the twins". It is part of the winter sky, lying between Taurus to the west and the dim Cancer to the east, with Auriga and the near-invisible Lynx to the north and Monoceros and Canis Minor to the south. The Gemini program is named for it. Notable Deep Sky Objects Open Cluster M35 . It also contains many interesting nebulas and star clusters. NGC 2158 is just southeast of M35. Also of note is the unique Eskimo Nebula, (also known as the Clownface Nebula) just southeast of the NGC 2420 open star cluster. Far northeast of this cluster lies NGC 2371, a planetary nebula next to the Gemini twin on the right.

Another popular nebula in Gemini lies in the southern tip of the constellation, Abell 21 the Medusa Nebula. Also, there's something unknown at Dec 28°17'52.29" RA 7h46m21.75s . Mythology Since this constellation is easily viewable as two parallel stick figures [1], considering faint stars visible to the naked eye, it was associated with the myth of Castor and Polydeuces (also known as Pollux), collectively known as the Dioscuri. A myth of these twins heavily concerns cattle theft, and may be connected to early views of the Milky Way, as a herd of dairy cows or cattle, by which they are situated. The fatness of the constellation can vary (since they readily form stick figures whether leaning right or left), though the twins are usually viewed as left leaning. However, when right leaning, one of the twins resides in the Milky Way, and the other outside it, a situation making it appear that one of the twins is stealing the cattle, and the other is observing.

In this situation, together with the area of the sky that is deserted (now considered as the new and extremely faint constellations Camelopardalis and Lynx), and the other features of the area in the Zodiac sign of Gemini (i.e. Orion, Auriga, and Canis Major), this may be the origin of the myth of the cattle of Geryon, which forms one of The Twelve Labours of Heracles. Astrology In tropical astrology it is associated with the decorated floral profusion of symbol for Gemini is the male lovers. Gemini are communicators of the Zodiac. They are also the nonconformists of the Zodiac. Graphic visualization The stars of the constellation Gemini can be connected in an alternative way, which graphically shows a pair of twins holding hands. Diagram of an alternate way to connect the stars of the Gemini constellation. A pair of twins are shown holding hands. The twin to the right is Castor, whose brightest star is alpha Geminorum (more commonly called Castor), is of the second magnitude, and represents Castor's head.

The twin to the left is Pollux, whose brightest star is beta Geminorum (more commonly called Pollux), is of the first magnitude, and represents Pollux's head. Pollux's torso is represented by star upsilon Geminorum, Pollux's right hand by iota Geminorum, Pollux's left hand by kappa Geminorum: all three of these stars are of the fourth magnitude. Pollux's pelvis is represented by star delta Geminorum, Pollux's right knee by zeta Geminorum, Pollux's right foot by gamma Geminorum, Pollux's left knee by lambda Geminorum, and Pollux's left foot by xi Geminorum. Gamma Geminorum is of the second magnitude, while delta and xi Geminorum are of the third magnitude. Castor's torso is represented by the star tau Geminorum, Castor's left hand by iota Geminorum (which he shares with Pollux), Castor's right hand by theta Geminorum: all three of these stars are of the fourth magnitude.

Castor's pelvis is represented by the star epsilon Geminorum, Castor's left foot by nu Geminorum, and Castor's right foot by mu Geminorum and eta Geminorum: epsilon, mu, and eta Geminorum are of the third magnitude. Arts Facts About the Constellation Gemini Lucky Gem: Agate Key Body Parts: Arms, Shoulders, Lungs Cosmic Strengths : They are adaptable and very versatile. Highly intellectual with good communicative skills, spontaneous, youthful, and talkative. Cosmic weaknesses : They are changeable, inconsistent, restless, inquisitive, sometimes cunning and secretly nervous. Chinese Counterpart : Horse {Image credit : above right : Mythological image of Gemini: } slide 5 of 8 Other Interesting Facts Mythology: The twin stars, Castor and Pollux collectively called Dioscuri, were the offspring of Leda, but each of them had a different father. As a result, Castor was mortal while Pollux was immortal. The two brothers lived as one, and as one of the rewards Zeus/Jupiter placed their image among the stars as the constellation of Gemini, The Twins.

In Arabian mythology, the twins were said to be a pair of peacocks. The Egyptians acknowledged the two stars as a pair of young goats. Historical significance: The exact origin of this symbol is not fully known. The two stars, Castor and Pollux are said to represent two stick figures and symbolizes the number II in Roman numerals. This is the constellation's symbol for the twin god as seen above. The twin stars in China represent the dual forces of nature, the yin and the yang. Castor and Pollux are also said to be associated with the founders of Rome, Romulus and Remus. {Image credit : below : Gemini - The twins : } slide 6 of 8 slide 7 of 8 Some Cool facts Gemini is the Latin term for twins. The name for this constellation in Sanskrit is "Mithun". This is a constellation of the Northern hemisphere. The twin stars of Castor and Pollux lie between Taurus to the west, and Cancer to the east, with Auriga and Lynx in the north and Monoceros and Canis Minor in the south. Castor is a binary star and Mercury governs the twins. Open Cluster M35 is the part of Gemini.

NGC 2158 lies in the southeast of M35. Also of importance is the exclusive Eskimo Nebula, which is also known as the Clown face Nebula. This is southeast of the NGC 2420 open star cluster. To the far northeast of this cluster lies NGC 2371, a planetary nebula next to the Gemini twin on the right. Another popular nebula in Gemini is on the southern tip of the constellation, Abell 21 the Medusa Nebula. Almost 2000 years ago the summer solstice lay in Cancer. However, now it lies in Gemini. Gemini attains its uppermost position in the evening sky in February. {Image Credit : Open Star clusters : M35 and NGC 2158: "NOAO/AURA/NSF". } slide 8 of 8 gemini constellation : definition of gemini constellation and synonyms of gemini constellation (English) Location The constellation Gemini as it can be seen with the naked eye, with added connecting lines.

Gemini lies between Taurus to the west and Cancer to the east, with Auriga and Lynx to the north and Monoceros and Canis Minor to the south. The Sun resides in Gemini from 21 June to 21 July each year. By mid August, Gemini will appear along the eastern horizon in the morning sky prior to sunrise. The best time to observe Gemini at night is overhead during the months of January and February. By April and May, the constellation will be visible soon after sunset in the west. The easiest way to locate the constellation is to find its two brightest stars Castor and Pollux eastward from the familiar “V” shaped asterism of Taurus and the three stars of Orion ’s belt. Another way is to mentally draw a line from the Pleiades star cluster located in Taurus and the brightest star in Leo , Regulus . In doing so, you are drawing an imaginary line that is relatively close to the ecliptic , a line which intersects Gemini roughly at the midpoint of the constellation, just below Castor and Pollux. Notable features Stars The brightest stars in Gemini are Castor and Pollux .

Although Castor has the Bayer designation "Alpha," it is actually the second brightest in the constellation after Pollux. Castor is a sextuple star system . Pollux has an extrasolar planet revolving around it, as do two other stars in Gemini, HD 50554 , and HD 59686 . Another noteworthy star is Mekbuda (ζ Gem), a supergiant with a radius that is 60 times solar, making it approximately 220,000 times the size of the Sun . U Geminorum is a dwarf nova type cataclysmic variable discovered by J.R. Hind in 1855. [2] Deep-sky objects To look at Gemini is to look away from the Milky Way ; as a result, there are comparatively few deep-sky objects of note. The Eskimo Nebula and Medusa Nebula , Messier object M35 , and Geminga are those that attract the most attention. The Eskimo and Medusa nebulae are both planetary nebulae , the one approximately 2,870 light years away and the other 1,500 light years distant.

M35 is an open star cluster which was discovered in the year 1745 by Swiss astronomer Philippe Loys de Chéseaux . And Geminga is a neutron star approximately 550 light years from Earth . Other objects of note are NGC 2129 , NGC 2158 , NGC 2266 , NGC 2331 , NGC 2355 , and NGC 2395 . Mythology Gemini as depicted in Urania's Mirror , a set of constellation cards published in London c.1825. In Babylonian astronomy , the stars Castor and Pollux were known as the Great Twins (MUL.MASH.TAB.BA.GAL.GAL). The Twins were regarded as minor gods and were called Meshlamtaea and Lugalirra, meaning respectively 'The One who has arisen from the Underworld' and the 'Mighty King'. Both names can be understood as titles of Nergal, the major Babylonian god of plague and pestilence, who was king of the Underworld.

[3] In Greek mythology , Gemini was associated with the myth of Castor and Pollux , collectively known as the Dioscuri . When Castor died, because he was mortal, Pollux begged his father Zeus to give Castor immortality, and he did, by uniting them together in the heavens. Visualizations Diagram of H.A. Rey 's alternative way to connect the stars of the constellation Gemini. A pair of twins are shown holding hands. The constellation contains 85 stars visible to observation on Earth without a telescope. [4] [5] Gemini is dominated by Castor and Pollux , two bright stars that appear relatively close together, encouraging the mythological link between the constellation and twinship. The twin above and to the right (as seem from the Northern Hemisphere) is Castor, whose brightest star is α Geminorum (more commonly called Castor); it is a second magnitude star and represents Castor's head. The twin below and to the left is Pollux, whose brightest star is β Geminorum (more commonly called Pollux); it is of the first magnitude and represents Pollux's head.

Furthermore, the other stars can be visualized as two parallel lines descending from the two main stars, making it look like two figures. H.A. Rey has suggested an alternative to the traditional visualization that connected the stars of Gemini to show a pair of twins holding hands. Pollux's torso is represented by the star υ Geminorum , Pollux's right hand by ι Geminorum , Pollux's left hand by κ Geminorum ; all three of these stars are of the fourth magnitude. Pollux's pelvis is represented by the star δ Geminorum , Pollux's right knee by ζ Geminorum , Pollux's right foot by γ Geminorum , Pollux's left knee by λ Geminorum , and Pollux's left foot by ξ Geminorum . Gamma Geminorum is of the second magnitude, while Delta and Xi Geminorum are of the third magnitude. Castor's torso is represented by the star τ Geminorum , Castor's left hand by ι Geminorum (which he shares with Pollux), Castor's right hand by θ Geminorum ; all three of these stars are of the fourth magnitude.

Castor's pelvis is represented by the star ε Geminorum , Castor's left foot by ν Geminorum , and Castor's right foot by μ Geminorum and η Geminorum ; ε, μ, and η Geminorum are of the third magnitude. The brightest star in this constellation is Pollux. Gemini in the history of astronomy In Meteorologica (1 343b30) Aristotle mentions that he observed Jupiter in conjunction with and then occulting a star in Gemini. This is the earliest known observation of this nature. [6] A study published in 1990 suggests the star involved was 1 Geminorum and the event took place on 5 December 337 BC. [7] When William Herschel discovered Uranus on 13 March 1781 it was located near Eta Geminorum . [8] In 1930 Clyde Tombaugh exposed a series of photographic plates centred on Delta Geminorum and discovered Pluto .

[9] Equivalents In Chinese astronomy , the stars that correspond to Gemini are located in two areas: the White Tiger of the West (西方白虎, Xī Fāng Bái Hǔ) and the Vermillion Bird of the South (南方朱雀, Nán Fāng Zhū Què). Astrology Main article: Gemini (astrology) As of 2008 [update] , the Sun appears in the constellation Gemini from June 20 to July 20. In tropical astrology , the Sun is considered to be in the sign Gemini from May 22 to June 22, and in sidereal astrology , from June 16 to July 15.

Wednesday, June 20, 2007 Born on the 30th day of May, I happen to be a Gemini. Let me start my blog by identifying what it means to be a Gemini... Gemini , is one of the constellations of the zodiac known as "the twins". It is part of the winter sky, lying between Taurus to the west and the dim Cancer to the east, with Auriga and the near-invisible Lynx to the north and Monoceros and Canis Minor to the south. The Gemini program is named for it.

However, when right leaning, one of the twins resides in the Milky Way, and the other outside it, a situation making it appear that one of the twins is stealing the cattle, and the other is observing. In this situation, together with the area of the sky that is deserted (now considered as the new and extremely faint constellations Camelopardalis and Lynx), and the other features of the area in the Zodiac sign of Gemini (i.e. Orion, Auriga and Canis Major), this may be the origin of the myth of the cattle of Geryon, which forms one of The Twelve Labours of Heracles. Astrology In tropical astrology it is associated with the decorated floral profusion of late spring and early summer. In sidereal astrology it is associated with the constellation Gemini and the Greek myth of Castor and Pollux . Gemini is associated with the classical element Air, and thus called an Air Sign (with Libra and Aquarius ). It is also one of the four mutable signs (along with Virgo, Sagittarius, and Pisces ). Its polar opposite is Sagittarius . It is the domicile of Mercury .

Each astrological sign is assigned a part of the body, viewed as the seat of its power. Gemini rules the nervous system, the lungs, the hands and arms. The symbol for Gemini is the twins . Gemini are communicators of the Zodiac . They are also the nonconformists of the Zodiac . Graphic visualization The stars of the constellation Gemini can be connected in an alternative way, which graphically shows a pair of twins holding hands.

That is not firm yet. There are no plans now for the Aries solid fuel rocket, besides using it as a technology reference for commercial rocket developers.What will the Ares and Orion spacecraft be used for, now that Obama has canceled the Constellation Program?Ares I probably won't be built. The same applies for Ares V, though some people in the Congress are pushing for a similar heavy lift launcher. Under the compromise plan, Orion was supposed to be re-purposed as a "lifeboat" for the International Space Station, but Lockheed Martin wants to finish it with its own money and launch it atop a Dealta IV Heavy launcher: 鈥?/a> meaning the closer to the middle the more like that sign he/she would be and what about after the center of the constellation has been passed?? why so for this?? Thanks for your answers!Would the closer a persons sun to the middle of a constellation ....make him/her more like that sign?Actually, that's not really true. All signs have three decans within them, taken from the three signs of the same element, and they go in order. For example Libra is divided into the Libra, Aquarius, and Gemini decans.

So, a Libra born in the Libra decan (Sept 23- Oct 2nd) is more "Libra-like" than say, a Libra born in the Aquarius decan, though all are definitely Libras. With every sign, the first 8-10 days or so are the most like their "textbook sun sign" if no other factors are involved. However what you might be feeling is the fact that a person born in the middle of his/her sign has a large probability of also having a Venus or Mercury sign placed in the same sign as their Sun. For example my girlfriend has a middle sign birthday (Pisces decan of Scorpio) and has a matching Venus and Mercury. I am born closer to the cusp (Sag/Scorp) though not ON the cusp, and have Sagittarius sun and Mercury, but I have a Scorpio Venus. This is how I would put it. Being born in the beginning of a sign gives you the "core values" of that sun sign.

Being born in a different decan, but with other planets in the sun sign, gives you styles of expressing yourself that are most like your sun sign--though you you may display more core values of your general element(water, air, earth,fire). ^_^Would the closer a persons sun to the middle of a constellation ....make him/her more like that sign? No.Would the closer a persons sun to the middle of a constellation ....make him/her more like that sign?Superstitious nonsenseWould the closer a persons sun to the middle of a constellation ....make him/her more like that sign? no, I think, its actually the closer to the start. I know for the ascending signs and moon sign, the smaller the degree, the bigger the influence, so i assume its the same for sun sign.Would the closer a persons sun to the middle of a constellation ....make him/her more like that sign?There are things called decanates in astrology - the first ten degrees of a sign is the strongest and purest of the sign.

For example scorpio would be a pure scorpio if the sun was in the first 10 degrees, the second ten degrees would be a scorpio with a tinge of pisces and the last ten degrees would be a scorpio with a tinge of pisces 鈥?/a>Would the closer a persons sun to the middle of a constellation ....make him/her more like that sign? Actually, it's the beginning of the sign...it's simple mathematics... When something is moving forward, it has more momentum...the pressure is more full force. Thats why the first decante of pisces is pisces as well.. It's like a train whistle, when it's coming at you it's getting louder, it has more strength adn momentum behind it...the middle is loudest, but it's also closer to fading out... 6 External links [edit] Notable Deep Sky Objects Gemini contains only one Messier Object, Open Cluster M35.

[edit] Astrology The Western astrological sign of Gemini forms part of the tropical zodiac (May 21 - June 20) and of the sidereal zodiac (June 15 - July 16). Note that according to the IAU, the sun enters the constellation at June 21 and leaves it at July 21. However, these dates are based on the currently defined borders of Gemini which were purely drawn for navigational purposes without consideration for use by astrology. In tropical astrology it is associated with the decorated floral profusion of late spring and early summer. In sidereal astrology it is associated with the constellation Gemini and the Greek myth of Castor (or Kastor) and Pollux.

Gemini is associated with the classical element Air, and thus called an Air Sign (with Libra and Aquarius). It is also one of the four mutable signs (along with Virgo, Sagittarius, and Pisces). Its polar opposite is Sagittarius. It is the domicile of Mercury. Each astrological sign is assigned a part of the body, viewed as the seat of its power.

The association of the two bright stars Castor and Pollux with twins goes back to Mesopotamia. Like all 88 modern constellations, the boundaries of Gemini were defined by the IAU (International Astronomical Union) in 1930.How was the constellation gemini discovered?Constellations aren't discovered, they are defined. They are arbitrary groupings of stars, and every culture has defined it's own, few of them have anything in common. We use the Greek constellations normally, so you're probably looking for 'it was DEFINED by the Greeks'. Examples?Do you know of any galaxies that can be found in more than one constellation?No, you have it backwards. The stars we see as formations called constellations all belong to the Milky Way Galaxy. Distant galaxies are catalogued separately and are NOT a part of any constellation.

The human eye was responsible for conjuring up the various patterns. Only stars qualify as members of a constellation, and ALL stars visible to the naked eye reside within our Milky Way. For the record, our classic constellation count is 88. But that's not the same as the Chinese, Egyptian, Norse. Navajo, Lakota Sioux, Inuit, Korean, Aztec, Inca or Dogon, to name only a few. Whether or not a galaxy can be found within the boundaries of a specific constellation is moot. You really need to consult "Messier Objects", New General Catalogue (NGC), and others to get a handle on the many, many locations of galaxies in the night sky. The Hubble Space Telescope has given us a good estimate of 172 billion galaxies scattered out there. Whare would you like to start? BTW, how many times are you going to ask variants of this same question, dude?Do you know of any galaxies that can be found in more than one constellation?Most galaxies are very small in angular size. There are undoubtedly a few minor examples which fall exactly on constellation boundaries, but they are merely oddities.

The only galaxy large enough to span more than one galaxy is the Milky Way, which winds through a couple of dozen constellations. [Edit] I just did a count, and the Milky Way runs hrough about 33 constellations. The Large Magellanic Cloud is split between two constellations, Mensa and Dorado, but the Small Magellanic Cloud is confined to Tucana.Do you know of any galaxies that can be found in more than one constellation?NGC 3321 , type Sb galaxy @ RA: 10h 38m 50.55s Dec: -11掳 38' 55.2" in the constellation Sextans is an extended object measuring 2.511'鈥?1.25', the center of which is only .08' from the boarder of Hydra. It necessarily over laps. It has a companion, NGC 3322 which likely does the same but I can find no info on it. It is a double constellation hopper.Do you know of any galaxies that can be found in more than one constellation?

If a galaxy were to sit right on the border between two constellations it could be in two. Since they are extended objects this is possible, but I can't think of any where it actually is the case. On a star map, what are the longitude and latitude co-ordinates of the constellation Cancer? Please help! I've looked all over the net and I would like, if possible, a straight forward answer. Thanks! :DOn a star map, what are the longitude and latitude co-ordinates of the constellation Cancer?Right ascension 9 h Declination +20掳On a star map, what are the longitude and latitude co-ordinates of the constellation Cancer?About the simplest way I've found for locating the (approximate) center of Cancer - either on most star maps or in the sky. is to draw an imaginary line from Pollux (in Gemini) to Regulus (in Leo). The center of Cancer is pretty much at the center of that imaginary line.

M44 (the lovely 'Beehive Cluster') can be found at RA 8.37, Dec+20.10On a star map, what are the longitude and latitude co-ordinates of the constellation Cancer?Lat long coordinates are land based points and do not change. However - news flash - the world is turning. The constellations are not in a static position. the long-lat....if you took one at a given moment would change. That's why you can't find it that way. The constellation has to be found relative to where other stars or constellations are.

Question: Which constellation, that lies between Taurus to the west and the dim Cancer to the east, with Auriga and Lynx to the north and Monoceros and Canis Minor to the south, is associated with the myth of Castor and Pollux, collectively known as the Dioscuri?
Answer: Gemini
