G 196-3 is a red dwarf with an apparent magnitude of 11.8 mag in the constellation Ursa Major. In 1998 Rebolo et al discovered. a substellares object (probably a brown dwarf ) of spectral type L2, which is very likely gravitationally bound to that star and is denoted by G 196-3 B. A rough estimate is likely its mass in the range of 25 Jupiter masses lie. The angular distance of the two objects is 16 " at a position angle of 209 °.
