BD-10°3166 is a K-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. 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.
