Sirius, the brightest star in the night sky, is a binary star system consisting of Sirius A and Sirius B. Sirius A, a main-sequence star, has a life expectancy of about 10 to 20 million years, while Sirius B, a white dwarf, represents the remnant of a more massive star that has already undergone its life cycle. The combined lifespan of the Sirius system reflects the evolution of its components, with Sirius A being relatively young at around 200 million years old.
