HD 114762
HD 114762 is a binary star〔 system approximately away in the constellation Coma Berenices. It consists of a yellow-white F-type main-sequence star and a red or brown dwarf companion approximately distant.〔 Both are low-metal subdwarfs. A telescope or strong binoculars are needed to view the primary. had been used by scientists as a "standard star", one whose radial velocity is well established, but with the discovery of exoplanet its usefulness as a standard has been called into question.〔

In 1989, a substellar object, , was found orbiting by Latham, ''et al''., using Doppler spectroscopy,〔 but its existence was not confirmed until 1991 by Cochran, ''et al''.〔 By 2012, its status as an exoplanet was confirmed.〔〔 It has a mass of at least , though this will be refined as its inclination is determined. Its orbital distance and revolution is similar to that of Mercury, though it has twice the eccentricity.〔
