Context: Sirius is a star system and the brightest star in the Earth's night sky. With a visual apparent magnitude of 1.46, it is almost twice as bright as Canopus, the next brightest star. The name "Sirius" is derived from the Ancient Greek  ("Seirios"), meaning "glowing" or "scorcher". The system has the Bayer designation Alpha Canis Majoris ( CMa). What the naked eye perceives as a single star is actually a binary star system, consisting of a white main-sequence star of spectral type A1V, termed Sirius A, and a faint white dwarf companion of spectral type DA2, called Sirius B. The distance separating Sirius A from its companion varies between 8.2 and 31.5 AU., Earth, otherwise known as the world, is the third planet from the Sun and the only object in the Universe known to harbor life. It is the densest planet in the Solar System and the largest of the four terrestrial planets., Sirius Canada was a Canadian company, a partnership between Slaight Communications, the Canadian Broadcasting Corporation and Sirius Satellite Radio, which was one of three services licensed by the CRTC on June 16, 2005 to introduce satellite radio service to Canada., Christian radio is a category of radio formats that focus on transmitting programming with a Christian message. In the United States, where it is most established, many such broadcasters play popular music of Christian influence, though many programs have talk or news programming covering associated topics that can have an economic or a political angle to them., XM Satellite Radio (XM) was one of the three satellite radio (SDARS) and online radio services in the United States and Canada, operated by Sirius XM Holdings. It provided pay-for-service radio, analogous to cable television. Its service included 73 different music channels, 39 news, sports, talk and entertainment channels, 21 regional traffic and weather channels and 23 play-by-play sports channels. XM channels were identified by Arbitron with the label "XM" (e.g., "XM32" for "The Bridge")., Family Talk is a Christian focused talk radio channel on the SIRIUS XM Radio service Sirius channel 161 and XM channel 131 ( previously 170 ) . It replaced FamilyNet Radio 's SIRIUS XM feed on November 30 , 2010 . It was added to XM Radio Canada on April 1 , 2007 . The station remained on SIRIUS 161 until May 4 , 2011 when SIRIUS XM moved the station on both XM and SIRIUS to Channel 131 ., A Bayer designation is a stellar designation in which a specific star is identified by a Greek letter, followed by the genitive form of its parent constellation's Latin name. The original list of Bayer designations contained 1,564 stars., A white dwarf, also called a degenerate dwarf, is a stellar core remnant composed mostly of electron-degenerate matter. A white dwarf is very dense: its mass is comparable to that of the Sun, while its volume is comparable to that of Earth. A white dwarf's faint luminosity comes from the emission of stored thermal energy; no fusion takes place in a white dwarf wherein mass is converted to energy. The nearest known white dwarf is Sirius B, at 8.6 light years, the smaller component of the Sirius binary star. There are currently thought to be eight white dwarfs among the hundred star systems nearest the Sun. The unusual faintness of white dwarfs was first recognized in 1910. The name "white dwarf" was coined by Willem Luyten in 1922. The universe has not existed long enough to experience a white dwarf releasing all of its energy as it will take many billions of years., The Canadian Radio-television and Telecommunications Commission (CRTC) is a public organisation in Canada with mandate as a regulatory agency for broadcasting and telecommunications. It was created in 1976 when it took over responsibility for regulating telecommunication carriers. Prior to 1976, it was known as the Canadian Radio and Television Commission, which was established in 1968 by the Parliament of Canada to replace the Board of Broadcast Governors. Its headquarters is located in the Central Building (Édifice central) of Les Terrasses de la Chaudière in Gatineau, Quebec., FamilyNet is an American family-friendly cable television network in over 25 million cable and satellite homes. The network was founded in 1979 as the National Christian Network, and took the name FamilyNet in 1988 under the ownership of Jerry Falwell. It is currently owned by Rural Media Group, which also owns RFD-TV., The apparent magnitude of a celestial object is a number that is a measure of its brightness as seen by an observer on Earth. The brighter an object appears, the lower its magnitude value (i.e. inverse relation). The Sun, at apparent magnitude of 27, is the brightest object in the sky. It is adjusted to the value it would have in the absence of the atmosphere. Furthermore, the magnitude scale is logarithmic; a difference of one in magnitude corresponds to a change in brightness by a factor of , or about 2.512., Sirius Satellite Radio is a satellite radio (SDARS) and online radio service operating in North America, owned by Sirius XM Holdings., XM Radio Canada was the operating name of Canadian Satellite Radio Holdings Inc. (or "CSR"), a Canadian communications and media company, which was incorporated in 2002 to broadcast satellite radio in Canada. Following the merger of Sirius XM Radio in the United States, XM Canada and its competitor Sirius Canada reached a deal in late 2010 to merge into Sirius XM Canada, which was approved by the Canadian Radio-television and Telecommunications Commission on April 11, 2011 and completed on June 21, 2011., A binary star is a star system consisting of two stars orbiting around their common barycenter. Systems of two or more stars are called "multiple star systems". These systems, especially when more distant, often appear to the unaided eye as a single point of light, and are then revealed as multiple by other means. Research over the last two centuries suggests that half or more of visible stars are part of multiple star systems., Satellite radio is  according to "article 1.39" of the International Telecommunication Unions (ITU) ITU Radio Regulations (RR)  a "Broadcasting-satellite service"., FamilyNet Radio was a Christian radio station that airs on SIRIUS Satellite Radio channel 161. It was a part of the FamilyNet organizations. It supported the merging of SIRIUS and XM Satellite Radio., A star system or stellar system is a small number of stars that orbit each other, bound by gravitational attraction. A large number of stars bound by gravitation is generally called a "star cluster" or "galaxy", although, broadly speaking, they are also star systems. Star systems are not to be confused with planetary systems, which include planets and similar bodies., Ancient Greek includes the forms of Greek used in ancient Greece and the ancient world from around the 9th century BC to the 6th century AD. It is often roughly divided into the Archaic period (9th to 6th centuries BC), Classical period (5th and 4th centuries BC), and Hellenistic period (3rd century BC to the 6th century AD). It is antedated in the second millennium BC by Mycenaean Greek., Canopus, also designated Alpha Carinae ( Carinae, abbreviated Alpha Car,  Car), is the brightest star in the southern constellation of Carina, and the second brightest star in the night-time sky, after Sirius. Canopus's visual magnitude is 0.74, and it has an absolute magnitude of 5.71., Canis Major is a constellation in the southern celestial hemisphere. In the second century, it was included in Ptolemy's 48 constellations, and is counted among the 88 modern constellations. Its name is Latin for "greater dog" in contrast to Canis Minor, the "lesser dog"; both figures are commonly represented as following the constellation of Orion the hunter through the sky. The Milky Way passes through Canis Major and several open clusters lie within its borders, most notably M41., Subject: familytalk, Relation: instance_of, Options: (A) 1 (B) 25 (C) article (D) atmosphere (E) bridge (F) building (G) cable television (H) category (I) century (J) change (K) channel (L) christian (M) cluster (N) company (O) constellation (P) designation (Q) distance (R) dog (S) dwarf (T) eight (U) electron (V) energy (W) family (X) harbor (Y) letter (Z) magnitude ([) mass (\) matter (]) merge (^) message (_) multiple star (`) music (a) name (b) network (c) news (d) orbit (e) parliament (f) partnership (g) planet (h) point (i) programming (j) public (k) radio (l) radio station (m) regulatory agency (n) scale (o) sequence (p) service (q) single (r) sky (s) star (t) star cluster (u) star system (v) station (w) system (x) three (y) union (z) value ({) white dwarf
