It was inconspicuous enough not be included in the Draper catalog (HD). The Hipparcos satellite also did not study it, so its true distance is poorly known. The distance measured by the Gaia spacecraft of 268 light years rules out a suggested companion star, LP 731-076, being its true binary star companion.[12][1]It also has a similar radius to Sirius A Stellar characteristicsThe star is very enriched with metals, being about three times as metal-rich as the Sun. Planets are common around such stars, and BD-10°3166 is not an exception. In 2000, the California and Carnegie Planet Search team discovered an extrasolar planet orbiting the star. Planetary systemIn 2000, the California and Carnegie Planet Search discovered a hot Jupiter-type extrasolar planet that has a minimum mass less than half that of Jupiter's, and which takes only 3.49 days to revolve around BD-10°3166.[15] {{OrbitboxPlanet begin| table_ref = [15] }}{{OrbitboxPlanet | exoplanet = b | mass = >0.458 ± 0.039 | period = 3.48777 ± 0.00011 | semimajor = 0.0452 ± 0.0026 | eccentricity = 0.019 ± 0.023 | radius = 1.03 }}{{Orbitbox end}} See also
