Solar systeme

Id Solar Systeme est id gravitation-ye bohndt planetar systeme os Sowel ed ios sanschan tournend we revolvend ambh id, kweter direct-ye au indirect-ye. Ex tod sanschan, ia largest sont ia oct planetes, id reste consistend smulker sanschan, kam ia penkwe nanplanetes ed id smulk sanschan ios Solar Systeme. Ex id sanschan in indirect orbit ambh Sowel - ia meuns - dwo sont larger quem id smulksto planete, Mercur. 
Id Solar Systeme wierdh 4,6 milliards yaren prever ex id gravitational collapse os gigant interstellar molecular nebh. Id vast majoritat ios masse ios systeme est skipen ab Sowel, menxu id majoritat ios reste est mathmounen in Jupiter. Ia quar smulker inner planetes, Mercur, Venus, Terra ed Mars, sont telluric planetes, consistend preter-ye rock ed metall. Ia quar uder planetes, Jupiter ed Saturn, sont gasgigants, consistend khaliban hydrogen ed helium; ia dwo udst planetes, Uranus ed Neptune, sont glehdjgigants, consistend khaliban substances samt nisbatan hog tahpoints comparen ad hydrogen au helium, kam wed, ammonia ed methane. Vasya oct planetes hant quasi circular orbits qua arehct un fictice platto disko kalen id Megagmo. 
Id Solar Systeme mathmount semschi smulker sanschan. Id asteroidenyeusmen, quod swehbht inter ia orbits om Mars ed Jupiter, mathmount khaliban sanschan compost, kam ia telluric planetes, ex rock ed metall. Trans Neptunes orbit swehbht id Kuiper yeusmen ed id disparsendisk, sont-ye populations os transneptune sanschan compost khaliban ex glehdja, ed trans ta uno nuper aunstohgen population sednoiden. Eni ta populations sont plur douzens do maghses decen om tusents os sanschan kafi large pro esus rundihn ab ir wi gravitat. Solg sanschan kweit ka nanplanetes. Identifiet nanplanetes include id asteroido Ceres ed id transneptune sanschan Pulto ed Eris. Ulter ta dwo iklimes, divers alya smulksanschan populations, includend cometes, gvondervs ed interplanetar duilnebhs, swehbhe leudher inter iklimes. Six iom planetes, ed minst-ye quar iom nanplanetes, ed maungs ex id smulker sanschan, sont orbit-ye begirt ab natural satellites, biadet kalen "meuns", kam besonters Terras Luna. Ielg iom uder planetes est ghohrdt ab planetara rings ex duil ed alya smulk sanschan. 
Id Solar Wind, un strohm om chargen particules dehnend ex Sowel, creet un burbule-like iklime in id interstellar milieu kalt id heliosphere. Id heliopause est id point ye-yod id pressem ex id solar wind est egal ei witer pressem ex id interstellar milieu; id oistrehct tiel id bors ios disparsendisk. Id Oort nebh, de-yod est mohnt id est id surce pro longperiode cometes, maghiet wehse ye edvas tusents dalger quem id heliosphere. Id Solar Systeme lyehct in id Orion Brakh, 26 000 luce-yares ud id centre ios Melgvia galaxia. 
==Asteroids ed meteorites==
Pleist asteroids wehse in id vast rewos oistrehcend inter ia orbits om Mars ed Jupiter, menxu ia meteroids sont spohrn towsraen. Oik asteroids hant sem pauk centens kilometern long radius, bet pleista sont maung-ye smulker. Pelu asteroids samkwehke ia carbonwenta chondrites, ed ir densitat est mukhtmel-ye lyter quem tod iom ordinar ghianshieks. 
Plur tusents asterioden, quom orbits buir hissaben samt yakinia, buir inventarn. Ia smulkst asteroids kwehke gnahvs ex collisions inter larger asteroids; sigwra exist maung sanschan quod ne buit dyohrct med photographic observation. 
Id orbit molten asteroids ed tod os Mars meisge, ed tod iom asteroids ios Apollo grupp ed tod os Terra meisge, we hatta penetre meis endo id inner Solar Systeme. Also, sem astronoms mehne od ia meteorites qua heihnt Terra sont quasi semper asteroidenfragments ios Apollo grupp lut unte collisions. Taghi asteroids ghehde hihes Terra au oino iom telluric planetes. Sont kalen "Terrameisgers". Alya asteroids, saycta "Troian planetes", sehkwnt we precedde Jupiter ye circa 60° binisbat ids orbit. Ta skaun-ye stable positions buir namdeht "Lagrange points". Ne est excluden an samlik duilswarms existe unte Lunas orbit, sehkwnd we preceddend id unte 60° (ta stets sont yando kalt ia Lagrange points L4 ed L5), bet iro presence ne hat est confirmet.
 Ia uder planets (in id aptergrund) Jupiter, Saturn, Uranus ed Neptune, binisbat ia inner planets Terra, Venus, Mars ed Mercur (in id prodgrund).
==Cometes==
Ia cometes, ex qua sems sont spectacular, gwehme ex exter iklimes, yando meg piern, ios Solar Systeme. Kwehkent habe, daydey, un oika kilometers long radius ed ses oiskipen ab uno mix ex glehdja ed duils. Id exacto chemic buhsa est, lakin, baygh-ye complexe. 
Kun un comete penetret id inner Solar systeme, id biht tadrijan warmt ab Sowel. Ids glehdja bisteume. Bihnt it sluna mier wakels os votatil material qua vahnt bihe transformen, sub id effect iom solar luce ed wind, do un dwaschaw om individualisen atoms, molecules ed ions (leit khaliban de elements kam carbon, nitrogen, oxygen au hydrogen ed combinations tom elements). Tod steumen sleut kathalika maung duils ia glehdja frostbohnd. Id comete se keinct it med un kaysar, wa coma. Ye proscher Sowel, ye do un longer swayp strehct tod kaysar, pfehrst-yod witerom Sowel. Mult complexe molecules buir decelen ab id spectroscopic analyse in ta cometar swayps. Ia ions ed duils present in id kaysar ne reagend exact-ye ye id sam weidos face id influence os Sowel, wardhent in druve dwo swayps : tod men ex gasa (au ions), seid ed moder, tod de ex duil, gehlb ed skamber. 
Pos nakus sien perihelium (sien orbitspoint prokwsto Sowel), id comete abpleuct kya dubes ios Solar Systeme, sien swayp semper orientet witerom Sowel. Ye dalger id gwaht, ye lyter bihnt ir activitat ed kaysar. Id vibiht un inert cometar eten tiel, maghses, sien niebsto pripleuk.
Astronoms enderkweite also ia "cortperiode cometes" (quos periode est sub 200 yars, kam id Halley comete, quod rireict Sowels vicinitat ye cada 76t yar) ed ia "longperiode" cometes, orbitisen meg elliptic-ye ed ops baygh inclinen unte id Megagmo.
 Ia sam planetes binisbat Sowel.
==Id Kuiper yeusmen==
Tod Kuiper yeusmen, ex id nam ios nederlandsgnahn astronom qui kwenchieusit ids existence in 1947. In 1992, dwo astronoms orbatend in id Haway tienmwenday, Jane Luu ed David Jewitt, aunstohg ids presto specimen, 1992 QB1. POn tod dien, circa tusent tos sanschan, namtios "transneptune", hat esto detect. 
Ir exact buhsa remant negnohht, sontghi meg pior pierna pro bihe analyset jixay-ye. Maghiet lites de un hybride sanschan, pwolasteroid pwolcomete, kam Chiron, tod plur centen kilometern plaut corpos, aunstohgen in 1977 kwehlend inter Saturn ed Uranus ed quod, proscher Sowel, wohng un kaysar. Id taiper taunghsto gnoht, Sedna, buit aunstohct in 2003 : inter 1300 ed 1800 km plaut, yani circa id dwidel os Luna, tod sanschanelement est taungher quem un asteroid bet smulker quem un planete. Periswehbht per sien orbit unte 10 000 yars, tiel 135 milliards km dalg ud Sowel.
Pluto, idso satellite Charon, ed kathalika Triton, Neptunes taunghsto satellite, gwehmient eti ois tod Kuiper yeusmen.
 Distance iom planetes (ne in ira respective meges !) binisbat Sowel.
==Origin ed evolution ios Solar Systeme==
Id Solar Systeme shayad gwehmt ois un fragment uns vast nebh ex interstellar gasa ed duils. Bi dusghapt sababs (maghses sekwos id explosion om nieber supernovas), tod nebulice hat inkapen collabe sub sien wi vyige. 
Sub id effect siens gravitational compaction, id nebulice hat tadrijan wardhto do un rotant plattihn disk, quer pressem, temperature ed densitat ieug ex id leizd tiel id centre. 4,6 milliards yaren prever, Sowel hat oistawt in id chaldst ed denssto central part ios nebulice. Pos id "daghen" iom nuclearen reactions in Sowels kerd, ids gwaydert hat minct ed id materiadisko quod periembh id hat srigascen. Ids gasic ambient hat solidascto do grans oiskipen, prokwem Sowel, ex ogwnsteug elements ed, dalger, ex divers glehdja. 
Per lelahsa os material, sub id effect om ir mutual collisions, ia grans hant gohnto smulk km-plaut (wa planetesimal) planetoids. Id natyehcen tos lelahsa hat ducen do id wardhen om sem circa 1000 km plaut planetar embryos. Ta planetar embryos, per ir mutual gravitational interactions, hant akapt iro crosct ed gohnt ia planetes. Id hol wardhen iom planetes hat jinkdoun per takriban 100 milliards yaren.
 Ex Sowel tiel id niebsto star : id Solar Systeme in un logarithmic maschtab om astronomic unitats (AU). 
==Id future ios Solar systeme==
Pos plu milliards yaren, Sowel habsiet exhausen sien hydrogen reserves ed mutawardhsiet. Id samel compacsiet in sien central ed bihsiet pelu meis volumineuso samt un ghemer surface temperature. Kun idso central temperature udchaldsiet 100 millions degreen, Sowel biaydhsiet sien helium. Id sessiet tun un rudho gigant, penkgims plauter quem nundiens, ed Terra sessiet un furnace. Quan idsa central iklimes sessient khaliban compost ex ia fusionproducts os helium, carbon ed oxygen, Sowel gnohsiet un nov instabilitatsprist. Kun habsiet exhaust sien hol nuclear dawti, ejecsiet brutal-ye sien vulbh, ed tod spandend gaskiaut gehnsiet un planetar nebulice. Sowels residual eten collapsiet pre forme un albh nan, quos erkwen siet decline lent-ye.
