11 Leonis Minoris (11 LMi) is a star system 37 light years away from Earth, in the constellation Leo Minor. The primary star is a yellow dwarf (main sequence) star of spectral type G8V, which is slightly more massive but slightly dimmer than our sun. The primary is an RS Canum Venaticorum type variable star and its brightness varies by 0.04 magnitudes.
There is also a secondary star, a red dwarf star much dimmer than the primary. It orbits in a highly eccentric orbit ranging from roughly 4 AU to 63 AU from the primary.
