Sirius–The Binary Star: Our Namesake
Sirius is the brightest star in the sky and the sixth nearest
star to Earth, at a distance of 8.6 light-years. Sirius, also known as
the Dog Star, is the prominent star in the Canis Major constellation.
Sirius actually consists of two stars, known as a binary star
system. The brightest of the two, named Sirius A, is a main-sequence
star with twice the mass of our Sun. Sirius B has evolved from a a
main-sequence star into a dense white dwarf, the result of having
consumed all of its nuclear energy. The Sirius star system is between
200 and 300 millions years old, compared to our Solar System at 4.5
billion years old.
