HD 87883 b
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
17 but does so at shorter intervals than other dwarf novae.
Two stars with planetary systems have been found. HD 87883 is an orange dwarf of magnitude 7.57 and spectral type K0V 18 parsecs distant from Earth. With a diameter three quarters that of Earth's sun, it is only 31 percent as luminous. It is orbited by a planet around 1.78 times the mass of Jupiter every 7.9 years, and there are possibly other smaller planets. HD 82886 is a yellow dwarf of spectral type G0
