What is the common name for the star Sirius

Dog Star
Sirius (/ˈsɪriəs/) is the brightest star (in fact, a star system) 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 Σείριος (Seirios), meaning "glowing" or "scorcher".

The system has the Bayer designation Alpha Canis Majoris (α 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.[24]

Sirius appears bright because of both its intrinsic luminosity and its proximity to Earth.

At a distance of 2.6 parsecs (8.6 ly), as determined by the Hipparcos astrometry satellite the Sirius system is one of Earth's near neighbors.

Sirius is gradually moving closer to the Solar System, so it will slightly increase in brightness over the next 60,000 years. After that time its distance will begin to increase and it will become fainter, but it will continue to be the brightest star in the Earth's sky for the next 210,000 years.
