HD 83443 b is an extrasolar planet approximately 134 light-years away[2] in the constellation of Vela. It was discovered in 2000 by the Geneva Extrasolar Planet Search Team led by Michel Mayor.[1] 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.[3]

The planet HD 83443 b is named Buru. The name was selected in the NameExoWorlds campaign by Kenya, during the 100th anniversary of the IAU. Buru means dust in the Dholuo language.[4][5]
