- HD_20868_b abstract "HD 20868 b is an extrasolar planet located approximately 159 light-years away in the constellation of Fornax, orbiting the 10th magnitude K-type subgiant star HD 20868. This planet has a minimum mass of 1.99 times more than Jupiter and orbits at a distance of 0.947 AU. This planet takes 380.85 days or 12.5 months to revolve around the star with an eccentricity of 0.75, one of the most eccentric of any known extrasolar planets. At periastron, the distance is 0.237 AU and at apastron, the distance is 1.66 AU.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.".
