However, it is not part of the Ursa Major moving group. Instead, it is an evolved helium-burning star, about 124 light years away. It is a multiple star, orbited by a main sequence companion, Dubhe B, at a distance of about 23 astronomical units (AU), as well as a close pair, Dubhe C, at a distance of about 8000 AU. The traditional name comes from the Arabic for "bear", dubb, from the phrase ظهر الدب الاكبر‎żahr ad-dubb al-akbar "the back of the Greater Bear".
