HD 87883 b is an extrasolar planet which orbits the K-type main sequence star HD 87883, located approximately 59 light years away in the constellation Leo Minor. It is a long-period planet, taking seven and a half years to orbit the star at the average distance of 3.60 AU. However, this planet orbits in a very eccentric path, which ranges distance from as close as 1.69 AU to as far as 5.51 AU. This planet was detected by radial velocity method on August 13, 2009.[1]
