Sirius is actually a binary star: Sirius A, which is a white main-sequence star and which is accompanied by Sirius B, a white dwarf.Around 100 years ago it was suggested that Sirius may belong to the Ursa Major moving group. However, more recent analysis of the motion of the stars in this group, and particularly Sirius's age, ha cast doubt on that suggestion. It is now believed that Sirius may be part of the Sirius Supercluster.
No, because they are not. Sirius A and B are just two stars in a Galaxy of many billions of stars. Sirius is a few hundred million years old, younger than most of the stars in the Milky Way.
No. There is no such thing a a cold star. Sirius consists of two stars, both of which are hotter than the average star.
From Wikipedia: "The age of the system [Sirius is a double star] is estimated at around 230 million years." So, a fairly young star, at least if compared to typical stars, including our own Sun.
Sirius, which consists of both Sirius A and Sirius B is in the constellation Canis Major, which, if you are looking south, appears below and to the left of Orion. Sirius B itself is too dim to be seen from Earth; the vast majority of the light from Sirius is from Sirius A. Even then, as a binary system, the two stars are too close together for us to see them separately.
Sirius is a binary star system consisting of two stars, Sirius A and Sirius B. Both stars have magnetic fields, but the specific properties of their magnetism are not well understood. It is known that magnetic fields play a role in the interaction between the two stars, but further research is needed to fully understand the magnetism of Sirius.
They are stars.
The similarities between red, blue, and yellow stars are that they are all types of stars found in the universe. The main difference lies in their temperature and life cycle: red stars are cooler and older, blue stars are hotter and younger, and yellow stars like our sun are middle-aged. Each type of star also emits different colors of light due to their temperature.

No. Sirius consists of two stars. Sirius A is larger than the sun but is not a giant. Sirius B is a white dwarf,

The differences in spectrum are mainly due to: * Differences in temperature between the stars * Differences in chemical composition * Differences in relative movement (redshift / blueshift, due to the Doppler effect)
The son is a mid size star so it is similar to many, but it is definitely not the biggest.
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 a star (actually, a binary star), so none, as stars do not have moons. Either or both of the stars that comprise Sirius could theoretically have planets which have moons, but if so, we don't know about them yet.
