Omicron Coronae Borealis has one confirmed planet, believed to be, along with HD 100655 b, one of the two least massive planets known around red clump giants. [5] The planet was detected by measuring changes in radial velocity of the host star caused by gravitational perturbation of the orbiting object.
Omicron Persei (ο Persei, abbreviated Omicron Per, ο Per) is a triple star system in the constellation of Perseus. From parallax measurements taken during the Hipparcos mission it is approximately 1,100 light-years (330 parsecs ) from the Sun .
40 Eridani is the system's Flamsteed designation and ο² Eridani (Latinised to Omicron 2 Eridani) its Bayer designation.The designations of the sub-components – 40 Eridani A, B and C – derive from the convention used by the Washington Multiplicity Catalog (WMC) for multiple star systems, and adopted by the International Astronomical Union (IAU).
