AK Leporis is a variable star in the southern constellation of Lepus the hare. It has an apparent visual magnitude of 6.141,[1] so, according to the Bortle scale, it is faintly visible from rural skies at night. This star forms a visual double with Gamma Leporis—the two have an angular separation of 97, making them difficult to separate with the naked eye even under the best conditions.[2] Both Gamma Leporis and AK Leporis are members of the Ursa Major Moving Group of stars that share a common motion through space.[3]

This is a BY Draconis variable star that undergoes slight brightness variations due to stellar activity. Differential rotation causes changes to the periodicity of the variation depending on the latitude of the activity.[4] X-ray emission has been detected from AK Leporis, and it is located at or near a radio source.[5]

Infrared observation of this star shows a large excess at a wavelength of 24 µm. This may be explained by the proximity of Gamma Leporis to the line of sight, or there may be a red dwarf companion or a dust disc. There is no excess observed at 70 µm.[6]
