HD 126614 is a trinary star^[14] system in the equatorial constellation of Virgo. The primary member, designated component A, is host to an exoplanetary companion. With an apparent visual magnitude of 8.81,^[7] it is too faint to be seen with the naked eye. The system is located at a distance of 239 light years from the Sun based on parallax measurements,^[1] but is drifting closer with a radial velocity of −33 km/s.^[8]
