BD-10°3166 b is an extrasolar planet approximately 268 light-years away in the constellation of Crater. This planet is a so-called "Hot Jupiter," a planet that orbits its parent star in a very close orbit. Distance to the star is less than 1/20th Earth's distance from the Sun. No transits by the planet have been detected, so the planet's orbital plane cannot be exactly aligned with our direction of view.[2]
