35 Comae Berenices
Star in the constellation Coma Berenices
35 Comae Berenices is a multiple star system in the northern constellation of Coma Berenices, located about 6° from the north galactic pole. It is faintly visible to the naked eye with an apparent visual magnitude of 4.93.[2] Based upon parallax measurements, it is located around 280 light years from the Sun.[1] The system is moving closer to the Earth with a heliocentric radial velocity of −6 km/s.[4]
This was found to be a wide binary by Struve in 1828,[3] but it has completed less than half an orbit since then and the orbital elements remain poorly constrained. It has an orbital period of 539±95 years and an eccentricity of 0.2±0.1.[5] The pair have been resolved into stellar classifications of an evolved G-type giant primary of class G5 III and an F-type secondary,[2] most likely main sequence with a class of F1 V.[3] The primary component is a spectroscopic binary[3] with a period of 7.9624 ± 0.0117 years and an eccentricity of 0.63.[4] A fourth component, 35 Com C, is located 29″ from the primary and may have a physical association.[3]
