83 Leonis Bb, also cataloged as HD 99492 b or abbreviated 83 Leo Bb, is an extrasolar planet approximately 58 light-years away in the constellation of Leo (the Lion). The planet was discovered in January of 2005 by the California and Carnegie Planet Search team, who use the Doppler spectroscopy method to detect planets. It is one of the smallest planets detected so far, having mass less than half that of Saturn. It orbits in a circular but a very close orbit around the star, completing one orbit in about 17 days.
