about 20 timesEarth’sdistance from the Sun. Despite the glare of the bright star, the eighth-magnitude companion is readily seen with a large telescope. This companion star,Sirius B, is about as massive as the Sun, though much more condensed, and was the firstwhite dwarf starto be ...
Sirius is the brightest star in the 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 ("glowing" or "scorcher"). The star has the Bayer designation Alpha C...
With an apparent magnitude of -1.44, Sirius is the 1st brightest star in the entire sky (see: 50 Brightest Stars ). Its absolute magnitude is 1.45 and its distance is 8.6 light years.The Equinox J2000 equatorial coordinates are RA = 06h 45m 08.9s, Dec = -16° 42' 58"....
Some are of the opinion that the apparent magnitude of Sirius is partly due to the whiteness of its tint and its greater intrinsic brilliancy; and that the red stars, Aldebaran, Betelgeuze, and others, would appear much brighter than now if of the same color as Sirius; rays of red light...
Sirius A has a companion star, the white dwarf Sirius B, which rotates around their center of common mass once every 50 years. However, it is around 10,000 times fainter than Sirius A, which in turn accounts for much of the apparent brightness (-1.46 mag.) we see here back on Earth...
