HD 114729 is a 7th magnitude star approximately 114 light years (35.0 parsec) away in the constellation of Centaurus. Like our Sun (G2V), it is a yellow dwarf (spectral type G3V). However, it is about 10% less massive than the Sun, but still twice as bright. That indicates a much greater age, perhaps over 10 billion years. HD 114729 is in a binary system with HD 114729 B. HD 114729 B has mass of 0.253 of the Sun.
In 2003 the California and Carnegie Planet Search team announced the discovery of a planet orbiting the star. This planet orbits twice as far away from the star as Earth to the Sun and orbits very eccentrically. It has mass 95% (0.840) that of Jupiter and 267 times the mass of Earth.
