HD 156846 b

HD 156846 b is an extrasolar planet located approximately 160 light-years away in the constellation of Ophiuchus, orbiting the star HD 156846. It has one of the most eccentric planetary orbits known. The high eccentricity of this planet's orbit is probably attributable to the presence of a red dwarf companion star. The average distance of the planet from HD 156846 is 0.99 AU, nearly identical to the distance of Earth from the Sun. The distance ranges from 0.15 AU to 1.83 AU with a 360 day period. It is also very massive with at least 10.45 Jupiter masses. The mass is a lower limit because the inclination of the orbit is not known; if its inclination and hence true mass became known, it would probably be found to be a brown dwarf.
