**HD 114837** is a suspected [binary star](/source/Binary_star)[7][3] system in the southern [constellation](/source/Constellation) of [Centaurus](/source/Centaurus_(constellation)). The brighter star is faintly visible to the naked eye with an [apparent visual magnitude](/source/Apparent_visual_magnitude) of 4.90.[1] It has a magnitude 10.2 candidate [common proper motion](/source/Common_proper_motion) companion at an [angular separation](/source/Angular_separation) of 4.2[″](/source/Second_of_arc), as of 2014.[3] The distance to this system, based on an annual [parallax shift](/source/Stellar_parallax) of 54.825[″](/source/Second_of_arc) as seen from Earth's orbit,[2] is 59.5 [light years](/source/Light_year). It is moving closer with a heliocentric [radial velocity](/source/Radial_velocity) of −64 km/s,[5] and will approach to within 21.8 ly in around 240,600 years.[11]

The primary component is an [F-type main-sequence star](/source/F-type_main-sequence_star) with a [stellar classification](/source/Stellar_classification) of F6 V Fe-0.4,[4] showing a mild underabundance of iron in its [spectrum](/source/Stellar_spectrum). It is about 3.4[9] billion years old with 1.14[7] times the [mass of the Sun](/source/Mass_of_the_Sun) and about 1.3[8] times the Sun's radius. This star is radiating 3.12[1] times the [Sun's luminosity](/source/Sun's_luminosity) from its [photosphere](/source/Photosphere) at an [effective temperature](/source/Effective_temperature) of 6,346 K.[9]
