BD-10°3166 is a G-type main sequence star approximately 218 light-years away in the constellation of Crater. 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. A recent photometric distance measurement gives an approximate distance of 218 light years. Although the estimate is only crude, it is probably good enough to exclude a suggested companion star, LP 731-076, being its true binary star companion.
The 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 planetorbiting the star.
In 2000, the California and Carnegie Planet Search discovered an extrasolar planet that has minimum mass 0.458 times that of Jupiter, which orbits at 0.0452 AU, taking only 3.49 days to revolve around BD-10°3166. This class of planet is called hot Jupiter.
