- HD_20782 abstract "HD 20782 is a 7th magnitude G-type main sequence star about 117 light-years away in the constellation of Fornax. HD 20782 is a part of a wide binary system with HD 20781, both stars host a planetary system. This is the first known case of planetary systems around both stars, the primary and secondary in the binary system. The companion is HD 20781. It has a very large angular separation of 252 arcsec, corresponding to 9080 AU at the distance of HD 20782. It is estimated to be 7.1 (± 4) billion years old, with a mass close to that of our Sun.An extremely eccentric extrasolar planet was announced around the primary star HD 20782 in 2006. In 2009 its orbit was narrowed down, and found to have the highest eccentricity of all known exoplanets, which distinction has stood as of 2012.And in 2011 two also-eccentric (but less so) Neptune-mass planets were announced around the secondary star HD 20781.".
