names = HIP 23889 bHD 33283 b is an
exoplanet orbiting aroundHD 33283 . Themass of the planet is about 1/3 that ofJupiter or about the same asSaturn . However, the planet orbits very close to thestar , taking only 18 days to complete its orbit with average speed of 86.5 km/s. Despite of this, its orbit is chaotic, bringing as close as 0.075 AU to as far away as 0.215 AU.See also
