BD-17°63 b is an extrasolar planet located approximately 112.5 light-years away in the constellation of Cetus, orbiting the 10th magnitude K-type main sequence star BD-17°63. This planet has a minimum mass of 5.1 MJ and orbits at a distance of 1.34 astronomical units from the star. The distance ranges from 0.62 AU to 2.06 AU, corresponding to the eccentricity of 0.54. One revolution takes about 656 days.[1]
This planet was discovered on October 26, 2008 by Moutou et al. using the HARPS spectrograph on ESO’s 3.6 meter telescope installed at La Silla Observatory in Atacama desert, Chile.
