HD 202206 c is an extrasolar planet discovered on November 16, 2004, using long-term observation of a formerly unconfirmed second planet after the discovery of a brown dwarf (first companion) around the star HD 202206.
[2] The planet orbits 3.07 times further out and is 85% less massive than the first companion, having a semi-amplitude of only 42 m/s.
Its minimum mass is 2.44 times that of Jupiter and its diameter is likely roughly the same size as Jupiter's.
[2] Further observation of this system via astrometry revised this picture in 2017, showing that HD 202206 c is a brown dwarf or super-Jupiter, with a true mass 17.9 times that of Jupiter, in a circumbinary orbit around a pair of co-orbiting stars being viewed nearly face-on.
