C3 Centauri
Star in the constellation Centaurus
C3 Centauri is a suspected astrometric binary[8] star system in the southern constellation of Centaurus. It has an orange hue and is dimly visible to the naked eye with an apparent visual magnitude of +5.46.[2] The distance to this object is approximately 342 light years based on parallax.[1] It is a member of the Hyades Stream of co-moving stars.[9]
The visible component of this system is an aging giant star with a stellar classification of K2 III,[3] which indicates it has exhausted the supply of hydrogen at its core then cooled and expanded off the main sequence. At present it has nearly sixteen[1] times the girth of the Sun. It is radiating 96[1] times the luminosity of the Sun from its swollen photosphere at an effective temperature of 4,535 K.[1]
