**C1 Centauri** is a single[8] [star](/source/Star) in the southern [constellation](/source/Constellation) of [Centaurus](/source/Centaurus). It has the [variable star designation](/source/Variable_star_designation) **V763 Centauri**, while *C1 Centauri* is the [Bayer designation](/source/Bayer_designation). The star has a red hue and is dimly visibly to the [naked eye](/source/Naked_eye) with an [apparent visual magnitude](/source/Apparent_visual_magnitude) that fluctuates around +5.64.[3] It is located at a distance of approximately 600 [light years](/source/Light_year) based on [parallax](/source/Stellar_parallax), and has an [absolute magnitude](/source/Absolute_magnitude) of −1.05.[3] It is drifting further away with a [radial velocity](/source/Radial_velocity) of +21 km/s.[2] At one time it was a candidate member of the [Zeta Herculis Moving Group](/source/Zeta_Herculis_Moving_Group) but has since been excluded.[9]

This object is an aging [red giant](/source/Red_giant) star on the [asymptotic giant branch](/source/Asymptotic_giant_branch)[4] with a [stellar classification](/source/Stellar_classification) of M3/4III.[5] Samus et al. (2017) classify this as a [slow irregular variable](/source/Slow_irregular_variable) of sub-type Lb and its brightness varies from magnitude +5.52 down to +5.82.[6] It was previously classified as a [semiregular variable](/source/Semiregular_variable) of sub-type SRb.[10] With the supply of hydrogen and helium at its [core](/source/Stellar_core) exhausted, the star has expanded until now it has 65 times the [radius of the Sun](/source/Radius_of_the_Sun). It is radiating 754 times the [luminosity of the Sun](/source/Luminosity_of_the_Sun) from its [photosphere](/source/Photosphere) at an [effective temperature](/source/Effective_temperature) of 3,761 K.[2]
