HD 75289 b is an extrasolar planet orbiting the star HD 75289 in Vela constellation.
It has a minimum mass half that of Jupiter, and it orbits in a very short orbit completing one circular revolution around the star in three and a half days.
[1] By studying the starlight scientists have concluded that the planet must have an albedo less than 0.12, rather low for a gas giant.
This planet was discovered by the Geneva Extrasolar Planet Search team using Doppler spectroscopy.
