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("scorcher"), possibly because the star's appearance was associated with summer. The star has the Bayer designation α Canis Majoris (α CMa, or AlphaCanis 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 typeA1V, termed Sirius A, and a faint white dwarf companion of spectral type DA2, termed Sirius B.
Sirius is also known colloquially as the "Dog Star", reflecting its prominence in its constellation, Canis Major (English: Big Dog).[14] The heliacal rising of Sirius marked the flooding of the Nile in ancient Egypt and the "Dog Days" of summer for the Ancient Greeks, while to the Polynesians it marked winter and was an important star for navigation around the Pacific Ocean.
The 'Dog Star' is a common nickname for Sirius since it is the brightest star in the constellation Canis Major, which means the Big Dog. It is also known as Sothis and Alpha Canis Majoris. The ancient Egyptians called it Sopdet. It was an important star in their calender used in predicting the Nile floods.
Sirius is the brightest star visible in the night sky at absolute visual magnitude -1.42. The brightest component of this binary star is called Sirius A.
