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.
