HD 212301 is a binary star system in the south circumpolar constellation of Octans. This star is also called HIP 110852. With an apparent visual magnitude of 7.76, it is too faint to be visible to the naked eye. The system is located at a distance of 177 light years from the Sun based on parallax, and is drifting further away with a radial velocity of +4.7 km/s. It has an absolute magnitude of 4.06. A hot jupiter candidate exoplanet was discovered orbiting the primary, based on radial velocity observations taken in 2003 and 2005.
