HD 87883 b is an extrasolar planet which orbits HD 87883, a K-type star on the main sequence, approximately 59 light years from Earth in the constellation of Leo Minor. It is a long-period planet, taking 8.23 years to orbit the star at the average distance of 3.77 AU in a very eccentric path, which ranges distance from 1.06 AU to 6.48 AU. It was detected by the radial velocity method on August 13, 2009.[2]
Astrometry of HD 87883 has determined an orbital inclination of either 16.8° or 163.2°, depending on whether the solution is prograde or retrograde. This, combined with the minimum mass, gives a true mass of 6.31 MJ (Jupiter masses).[1]
