HD 83443 b is an extrasolar planet approximately 142 light-years away in the constellation of Vela. It was discovered in 2000 by the Geneva Extrasolar Planet Search Team led by Michel Mayor. It has a minimum mass comparable to Saturn, and its orbit is one of the shortest known, 1/25th that of Earth's. It takes only three days to complete one revolution around the star. This hot Jupiter is likely to be slightly larger than Jupiter in radius.
