Lalande 21185 From Wikipedia the free encyclopedia. Lalande 21185: Here is a link to some basic data on this red dwarf star. Its mass is 46% that of the Sun, making it for a red dwarf positively obese. Lalande 21185, dim red dwarf M2V: Star mass, radii: 0.23, 0.35 x Sol: Notes:-Hypothetical planet location: 0.08 AU: Possible life: 5% . Lalande 21185 is a high proper motion star moving at about 5 arc seconds a year in an orbit perpendicular to the plane of the galaxy. Using data obtained from frequent observations of this star over the last 50 years, University of Pitsburgh astronomer George Gatewood recently announced that much of Lalande 21185's wobble is most likely due to an unseen planet with approximately 90% of the mass of Jupiter and an orbital period of 5.8 years.
