**HD 116243** is a single[8] [star](/source/Star) in the southern [constellation](/source/Constellation) of [Centaurus](/source/Centaurus). It has the [Bayer designation](/source/Bayer_designation) **m Centauri**, while *HD 116243* is the identifier from the *[Henry Draper catalogue](/source/Henry_Draper_catalogue)*.[7] This star has a yellow hue and is faintly visible to the naked eye with an [apparent visual magnitude](/source/Apparent_visual_magnitude) of +4.52.[1] It is located at a distance of approximately 244 [light years](/source/Light_year) from the [Sun](/source/Sun) based on [parallax](/source/Stellar_parallax),[2] and it has an [absolute magnitude](/source/Absolute_magnitude) of 0.01.[1] It is drifting further away with a [radial velocity](/source/Radial_velocity) of +13.3 km/s.[2]

This object is an aging [bright giant](/source/Bright_giant) star with a [stellar classification](/source/Stellar_classification) of G5IIb[3] With the supply of hydrogen at its [core](/source/Stellar_core) exhausted, it has expanded to 12 times the [radius of the Sun](/source/Radius_of_the_Sun). The star is radiating 89 times the [luminosity of the Sun](/source/Luminosity_of_the_Sun) from its enlarged [photosphere](/source/Photosphere) at an [effective temperature](/source/Effective_temperature) of 5,197 [K](/source/Kelvin).[2]
