HD 76700 is a star in the southern constellation of Volans. It is yellow in hue and is too faint to be visible to the naked eye, having an apparent visual magnitude of 8.16.[2] This object is located at a distance of 197 light years from the Sun based on stellar parallax.[1] It is drifting further away with a radial velocity of +39 km/s.[2]

Properties

This object is a G-type main-sequence star with a stellar classification of G6V,[3] which indicates it is generating energy through core hydrogen fusion. It is a metal-enriched star, showing a much higher metallicity than the Sun.[6] This may be explained by prior accretion of refractory-rich planetary bodies into the stellar atmosphere.[7] The mass of HD 76700 is very similar to (1.1 times) that of the Sun, but it is cooler and brighter (with an effective temperature of 5,694 K and luminosity of 1.69 Suns) and thus much older—around 6.9 billion years old.[4]

Planetary system

HD 76700 is orbited by a giant planet that was discovered in 2003 via the radial velocity method.[6] Designated HD 76700 b, this planet is orbiting very close to the star with a period of just four days.[8]
