BD−10°3166 is a K-type main sequence star approximately 268 light-years away in the constellation of Crater.
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.
[8][9] The star is very enriched with metals, being two to three times as metal-rich as the Sun.
[2] In 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.
