HR 5256 is a solitary, K-type main sequence star located thirty-three light-years away in the constellation Ursa Major. It has an estimated 80% of the Sun's mass and 78% of the Sun's radius.[6] The space velocity components of this star are (U, V, W) = (−2, −10, −25) km/s.[4] HR 5256 will make its closest approach to the Sun in about 333,000 ± 16,000 years, when it will be at a distance of 3.9 ± 0.2 parsecs.[9]
