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.
Basically the same stars that are near us, since Sirius is quite close, as stars go.
Sirius does not have any known planets.
No. Stars are too hot to support life.
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.
Voyager 2 will pass near sirius in 296,000 years.
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 XM Stars Too was created on 2005-02-05.
No, it is not a dwarf star. It's fairly large as stars go, but nowhere near the largest. However, because it is both fairly large and fairly close, Sirius is one of the brighter stars in our sky.

No. Sirius consists of two stars. Sirius A is larger than the sun but is not a giant. Sirius B is a white dwarf,
No. Sirius is actually two stars. The main body, Sirius A, is a fairly large star, larger than the sun, but it is nowhere near the size of a supergiant. Sirius B is a white dwarf, a small, dense remnant of a star that is, int his case, slightly smaller than Earth.
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.

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.
There are 8 main stars. Sirius is the brightest.
Voyager 2 will pass near sirius in 296,000 years.
Some stars are hotter then the Sun such as Sirius and Rigel.
Neither. The Sun only appears bright because it is close. Sirius is far larger and brighter than our Sun. Our Sun is probably in the top 40% of all stars in the Milky Way, while Sirius is probably in the top 5%. But there are many other stars that are far brighter even that Sirius.
