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.
What else can I help you with?
Are the stars of Sirius accepted as the origin of the Milky Way yet?
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.
When will Voyager reach Sirius?

What are the similarities and differences between sirius and sirius b stars?
Sirius, also known as Sirius A, is a main-sequence star and the brightest star in the night sky, while Sirius B is its companion, a white dwarf. Both stars are part of the same binary system and share a common origin, but they differ significantly in their characteristics; Sirius A is larger, hotter, and more luminous than Sirius B, which has exhausted its nuclear fuel and is much smaller and dimmer. Their orbital dynamics are also distinct, with Sirius B having a highly elliptical orbit around Sirius A. Overall, they illustrate the evolutionary stages of stars within a binary system.
Is Sirius A a cold star?
No. There is no such thing a a cold star. Sirius consists of two stars, both of which are hotter than the average star.

What is the magnetism of a Sirius star?
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.
How many moons does Sirius have?
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.

Can we find sirius star in our solar system?
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.
