Sirius
Many cultures have historically attached special significance to Sirius, particularly in relation to dogs. It is often colloquially called the "Dog Star" as the brightest star of Canis Major, the "Great Dog" constellation. Canis Major was classically depicted as Orion's dog. The Ancient Greeks thought that Sirius's emanations could affect dogs adversely, making them behave abnormally during the "dog days", the hottest days of the summer. The Romans knew these days as , and the star Sirius was called Canicula, "little dog". The excessive panting of dogs in hot weather was thought to place them at risk of desiccation and disease. In extreme cases, a foaming dog might have rabies, which could infect and kill humans they had bitten. Homer, in the "Iliad", describes the approach of Achilles toward Troy in these words:
cma (canis majoris) is so bright it is visible near the rising sun but is better known as Canis Major is a constellation which contains Sirius, the brightest star in the night sky how did this bright star gets its name? Its name is derived from the Greek word "Seirios" "glowing" or "scorching". can you name a few more bright stars? Sun, Spica etc can the former be viewed by the naked eye? The brightness of the Sun can cause pain from looking at it with the naked eye; however, doing so for brief periods is not hazardous for normal non-dilated eyes how was this bright star formed? It formed approximately 4.6 billion years ago from the gravitational collapse of matter within a region of a large molecular cloud. what are the different parts of its constitution? Core, Radiative zone, Tachocline, Convective zone, Photosphere any satellites used to study more about this body? NASA's Pioneers 6, 7, 8 and 9 ; Helios 1 and 2 probes with regards to the brightest star mentioned earlier in the conversation, how far is it from us? It is believed to have estimated the distance to Sirius at 27664 times the distance from the Earth to the Sun (about 0.437 light years, translating to a parallax of roughly 7.5 arcseconds).

Sirius [SEP] Etymology and cultural significance
The proper name "Sirius" comes from the Latin "Sīrius", from the Ancient Greek "Σείριος" ("Seirios", "glowing" or "scorcher"). The Greek word itself may have been imported from elsewhere before the Archaic period, one authority suggesting a link with the Egyptian god Osiris. The name's earliest recorded use dates from the 7th century BC in Hesiod's poetic work "Works and Days". In 2016, the International Astronomical Union organized a Working Group on Star Names (WGSN) to catalog and standardize proper names for stars. The WGSN's first bulletin of July 2016 included a table of the first two batches of names approved by the WGSN; which included "Sirius" for the star α Canis Majoris A.
