Gamma Leporis (γ Lep, γ Leporis) is a star that is located at a distance of about 29 light-years from Earth. Gamma Leporis lies in the south central part of the constellation Lepus, southeast of Beta Leporis and southwest of Delta Leporis. It has a common proper motion companion, AK Leporis, which is a variable star of the BY Draconis type.[9] The star is a member of the Ursa Major Moving Group.[5]
This star is larger than the Sun with 1.2 times the radius of the Sun and 1.3 times the Sun's mass.[5] Based upon its stellar characteristics and distance from Earth, Gamma Leporis was considered a high-priority target for NASA's Terrestrial Planet Finder mission.
