Is sirius a star or planet?

The star Sirius is not a planet or even a single star but is in fact a binary star, or two stars that orbit each other. Together, these two stars are often called The Dog Star, as they are the brightest object in the constellation Canis Major - or The Big Dog. The stars, named Sirius A and Sirius B, orbit each other about 20 Astronomical Units (the distance from the Sun to the planet Uranus) that takes about 50 years to complete on orbit. Right now, they appear to be moving away from each other and will reach their maximum separation on the year 2019. At a distance of roughly 8.6 light years, the Sirius binary star system is actually relatively close to us. Sirius A (the larger of the two binary stars) is also extraordinarily bright, about 25 time brighter than our sun. These two factors make Sirius one of the top ten brightest stars in our night sky. While Sirius A is very large and bright, Sirius B (the smaller of the two binary stars) is significantly smaller than it's companion - about the size of our Earth. But even at it's small size, Sirius B still has nearly the same mass as our Sun. That much mass in such a tiny space means more surface gravity (about twice that of Sirius A) and more heat (about 2.5 times that of Sirius A). Just because it's small, doesn't mean it's not awesome. Sirius is considered a wintertime star, usually only seen between the months of December and March. It is part of the Winter Triangle asterism along with Betelgeuse and Procyon. So if you're in the Northern Hemisphere and the weather begins to turn cold, take a look into the southern night sky and find Sirius, The Dog Star!


Which star is the biggest star known?

The biggest star that we know of is a red hypergiant called: VY Canis Majoris at 2,100 times the size of our Sun. VY Canis Majoris is in the same constellation as Sirius (The Dog Star). The sun is the star with the largest apparent size because it is the closest. Sirius (The Dog Star) is a binary star and the brightest star in the sky, other than the sun.
