HD 87883 is star in the northern constellation of Leo Minor. It is too faint to be viewed with the naked eye, having an apparent visual magnitude of 7.56.[2] The star is located at a distance of 59.7 light years from the Sun based on parallax,[1] and is drifting further away with a radial velocity of +9.3 km/s.[4] It has an absolute magnitude of 6.27.[5]
This is an ordinary K-type main-sequence star with a stellar classification of K0V.[3] It has a modest level of chromospheric activity,[5] and is rotating with a period of 38.6 days.[5] The star is smaller than the Sun, with 82% of the mass of the Sun and 76% of the Sun's radius. The age of this star is 9.8 billion years, compared with 4.6 billion years for the Sun. It is radiating 32% of the luminosity of the Sun from its photosphere at an effective temperature of 4,980 K.[5]
In August 2009, this star was found to have a planet via the radial velocity method. The orbital solution shows it to be a Super-Jupiter body in an elliptical orbit with a period of Script error: No such module "convert". and a typical separation of Script error: No such module "val".. A relatively high deviation on the model fit suggests there may be an additional planetary companion in a close, perturbing orbit of the star.[5] The orbital parameters of the known planet do not preclude the existence of an Earth-mass planet with a dynamically-stable orbit in the habitable zone.[8] Since its orbit is relatively face-on, its true mass deviates significantly from its minimum mass, at Script error: No such module "val"..[6][9]
