HD 202206 c is a planet discovered on November 16, 2004 by using long-term observation of formerly unconfirmed second planet after the discovery of brown dwarf (first companion) around the star.

The planet orbits 3.07 times further out and have 7.13 times less massive than first companion, making semi-amplitude much lower at only 42 m/s. The mass is 2.44 times Jupiter and roughly the same size in radius as Jupiter. The orbital resonance of planet with brown dwarf is 5:1. The eccentricity of planet is higher than all of the planets and dwarf planets in our solar system except Eris, which has eccentricity of 0.44.
