HD 187085 is a yellow–hued star in the southern constellation of Sagittarius. It is too faint to be visible to the naked eye, having an apparent visual magnitude of +7.225.[2] The star is located at a distance of approximately 1,010 light years from the Sun based on parallax,[1] and is drifting further away with a radial velocity of +18 km/s.[4]
This is an ordinary G-type main-sequence star with a stellar classification of G0V,[3] which means it is generating energy through core hydrogen fusion. It is younger than the Sun with an estimated age of 2.7 billion years and is spinning with a leisurely rotation period of around 21 days. The star is 27% larger and 19% more massive than the Sun.[2] It is radiating 2.3[1] times the luminosity of the Sun from its photosphere at an effective temperature of 6,117 K.[2]
In 2006, an extrasolar planet was announced orbiting HD 187085, with a minimum mass slightly below that of the planet Jupiter. It is orbiting the host star with a period of around 2.8 years.[6] The orbit overlaps the habitable zone of this star.[7] In 2009, the presence of an infrared excess was announced, suggesting a debris disk orbits the star.[8]
