The name "Sirius" is derived from the Ancient Greek Seirios ("glowing" or "scorcher"). The star has the Bayer designation Alpha Canis Majoris. 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, ...

Sirius (or Sirius A) is amain-sequence starof spectral type early A. Sirius B is one of the largest known white dwarf stars and is 10,000 times dimmer than Sirius. It’s so dim that astronomers couldn’t estimate its mass until 2005 by using data from theHubble Space Telescope. ...
The primary component is a white main sequence star of spectral type, A1V, named Sirius A. This star is the one visible to the naked eye. It has a radius of 1.7 times that of the Sun and is 25 times more luminous. In 1844, German astronomer Friedrich Bessel noticed that Sirius "...
