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.
Sirius is larger than Algol. Sirius is a binary star system with Sirius A being the larger star with about twice the mass of the Sun, while Algol is a triple star system with the main star being smaller than Sirius A.
High mass.
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).
Sirius is actually a binary star system, which means there are two stars (A & B).Sirius A is 25 times more luminous that our Sun. It is estimated to be twice as large as our Sun.It is a type A star and is thus classified as a between Sub Giant and Giant.Sirius B is a white dwarf and has the mass of the Sun but the size of the Earth.Both stars are spherical in shape.
Sirius's fate might be peaceful; just ejecting it's outer red giant layers to make a planetary nebula. It is 2.02 times the mass of the Sun. However, Sirius has a white dwarf companion. On Sirius B's death, Sirius A might have formed. At the other end, Sirius B might destroy Sirius A. White dwarfs have very strong gravity, and if it is close enough, Sirius B might steal material from Sirius A. When a white dwarf stealing mass from the parent star has enough mass to create iron, the iron triggers a Type 1a supernova. If this happens to Sirius B, Sirius A could either be destroyed by the immense force of the explosion, or become a runaway star, travelling faster than even Barnard's Star. If this is the case, Sirius A might eat smaller stars or crash and burn into a larger star. If it heads towards us if this happens, we would be doomed.
Sirius B is a white dwarf. So it is low mass compared to other stellar remnants.
Yes, Sirius is about twice as massive as our sun, making it a medium mass star. It is quite a bit brighter, however, and is the second brightest star in our sky.
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.
Sirius is larger than Algol. Sirius is a binary star system with Sirius A being the larger star with about twice the mass of the Sun, while Algol is a triple star system with the main star being smaller than Sirius A.
Yes, Sirius is about twice as massive as our sun, making it a medium mass star. It is quite a bit brighter, however, and is the second brightest star in our sky.
Sure - the two attract each other. In the case of a double star - as Sirius A and Sirius B - both revolve around their common center of mass.

No, Sirius is not an asteroid. Sirius is a binary star system consisting of the brighter star, Sirius A, and its companion, Sirius B, which is a white dwarf star. It is the brightest star in the Earth's night sky.
Polaris - the current North star is a multiple star system., consisting of the main star and smaller companions. The main star Alpha Ursae Minoris is a bright star, a 6 solar mass supergiant and it is a main sequence star. Orbiting very close to this main star is a white dwarf of roughly 1.5 solar masses. This is not a main sequence star. Orbiting further out is the third companion, a 1.39 solar mass star. This is a main sequence star. There are also two more distant components (α UMi C and α UMi D) - Polaris is thought to be part of an open cluster - I do not know if these later two stars are main sequence or not.
A white dwarf is the remnant of a low to medium mass star.
