HD 114729 is a Sun-like star with an orbiting exoplanet in the southern constellation of Centaurus. Based on parallax measurements, it is located at a distance of 124 light years from the Sun. It is near the lower limit of visibility to the naked eye, having an apparent visual magnitude of 6.68<ref name=Anderson2012/> The system is drifting further away with a heliocentric radial velocity of 26.3 km/s.<ref name=Soubiran_et_al_2018/> The system has a relatively high proper motion, traversing the celestial sphere at an angular rate of Template:Val·yr−1.<ref name=Luyten1995/>
The spectrum of HD 114729 presents as an ordinary G-type main-sequence star, a yellow dwarf, with a stellar classification of G0 V.<ref name="Gray2006"/> It has a negligible level of magnetic activity, making it chromosperically quiet.<ref name="Butler2003"/> The star has about the same mass as the Sun, but the radius has expanded to 44% greater than the Sun's girth. It is radiating more than double the luminosity of the Sun from its photosphere at an effective temperature of 5,939 K. The size and luminosity suggest a much greater age than the Sun; perhaps around nine billion years.<ref name="Bonfanti2016"/>
HD 114729 has a co-moving companion designated HD 114729 B, with the latter having 25.3% of the Sun's mass and a projected separation of Template:Val.<ref name=Mugrauer2005/>
Planetary systemEdit
In 2003 the California and Carnegie Planet Search team announced the discovery of a planet orbiting the star.<ref name="Butler2003"/> This planet orbits twice as far away from the star as Earth to the Sun and orbits very eccentrically. It has mass at least 95% (0.840) that of Jupiter and thus a minimum of 267 times the mass of Earth.
