Gamma Leporis (γ Lep / γ Leporis) is a multiple star system which is located at a distance of about 29 light-years from Earth and consists of 2 or 3 stars: Gamma Leporis A, Gamma Leporis B and possibly Gamma Leporis C.
Gamma Leporis lies in the south central part of the constellation Lepus, southeast of Beta Leporis and southwest of Delta Leporis. The system is a member of the Sirius group. Based upon its stellar characteristics and distance from Earth, Gamma Leporis is considered a high-priority target for NASA's Terrestrial Planet Finder mission.
