What is the size of Sirius?
Sirius is a binary star system consisting of two stars: Sirius A and Sirius B. Sirius A is the larger and more luminous star, with a diameter of about 1.7 times that of the Sun. Sirius B is a white dwarf star with a diameter of about 12,000 kilometers, roughly the size of Earth. The distance between the two stars is about 20 AU (astronomical units).
Is Sirius A considered a supergiant?
No. The diameter of Sirius A is about 1.7 times that of the sun. To be considered a supergiant a star must be at least 100 times the diameter of the sun.
Star that is bigger than the sun and the earth?
One example of a star bigger than the sun is Betelgeuse, which is a red supergiant star in the constellation of Orion. Its size is estimated to be around 1,000 times larger than the sun. The largest known star is UY Scuti, with a diameter thought to be about 1,700 times that of the sun. Both stars are significantly larger than Earth.
Who is the Brightest star other than sun?
Sirius is the brightest star in the night sky.
Is Sirius a low mass star?
It is, but at twice our suns mass, Sirius A is on the limit, of being an intimidate mass star. Sirius A will have a life cycle similar to that of our own star which is a low mass star, but burns hotter. Sirius B is a companion white dwarf star with a mass of around the same as our sun. Previously, it was thought to have been a star with a mass of around 5 times that of our sun, burning out more quickly than Sirius A.
Is Sirius brighter than the sun?
Yes it is much bigger.Probably 5 suns can fit in sirius.Not only is sirius bigger but it is much hotter as well.
Is sirius bigger than earth?
Yes. Sirius actually consists of two stars. The main object, Sirius A is not only bigger than Earth but is almost twice the diameter of the sun. The secondary star, Sirius B is a collapsed remnant of a star called a white dwarf. It is slightly smaller than Earth but far denser.
Is sirius larger than barnard?
Yes, Sirius is larger than Barnard's Star. Sirius, a binary star system, consists of Sirius A, which is about 2.1 times the mass of the Sun and has a diameter approximately 1.7 times that of the Sun. In contrast, Barnard's Star is a red dwarf with a mass only about 0.14 times that of the Sun and a much smaller diameter. Thus, Sirius is significantly more massive and larger than Barnard's Star.

Our solar system is centred round the Sun, which is our own star, while Sirius is a nearby star that is bigger and brighter than the Sun but a lot further away. Sirius can be found near the constellation of Orion, to the lower left of it when viewed from USA or Europe. It is the brightest of all the stars, but the planets Venus and Jupiter can be brighter at times.
Is Sirius A considered a supergiant?
No. The diameter of Sirius A is about 1.7 times that of the sun. To be considered a supergiant a star must be at least 100 times the diameter of the sun.
What size is the star Sirius?
Sirius is a double star; the larger of the pair is twice the mass of the Sun and about 1.7 times the Sun's radius. So it would be about 740,000 miles radius.. and would be about five times the Sun's volume.
How many times is the gamma star bigger than the sun?
