Sirius

Sirius is the brightest star in the night sky. While it is coming directly towards us, Sirius creates an axis of rotation with Earth relative to the stellar background. Because of this, of all the stars in the sky, only the annual heliacal rising of Sirius exactly matches the length of our solar year, 365.25 days. The Ancient Egyptians were somehow aware of this unique relationship between our system and Sirius and marked the heliacal rising of Sirius as the first day of their calendar year.This star can be located at a right ascension of 6h 22m 8.92s and a declination of -16°42' 58. Sirius belongs to the spectral class B3-B5 and has an absolute magnitude of -3.95. Sirius is distanced at 8 1/2 light years away from Earth.
