It is a main-sequence star with a classification of G8 V. 82 G Eridani is slightly smaller and less massive than Sol, making it marginally dimmer in terms of luminosity; about 20% more luminous than Tau Ceti or Alpha Centauri B.



82 G. Eridani is a high-velocity star—it is moving quickly compared to the average—and hence is probably a member of Population II, generally older stars whose motions take them well outside the plane of the Milky Way.

Three planets orbit 82 G. Eridani. The mass range of these planets classifies them as super-Earths; objects with only a few times Terra's mass.
