| dbo:abstract | HD 202206 c (بالإنجليزية: HD 202206 c) الذي يرمز له بالرمز HD 202206c، هو كوكب خارج المجموعة الشمسية، وكوكب حول نجم ثنائي، في كوكبة الجدي (كوكبة)، يتبع . (ar) 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. This was the first circumbinary planet to be found around a main sequence star. 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. The orbital resonance of the planet orbiting the brown dwarf is 5:1. The eccentricity of the planet is higher than that of all the planets and dwarf planets in the Solar System except Eris, which has an eccentricity of 0.44. 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. (en) HD 202206 c es el planeta del sistema de la estrella HD 202206, una estrella de la constelación de Capricornus, a 151 años luz del sistema solar. Tiene 2 veces la masa de Júpiter. Orbita a 2,55 ua de su estrella, en resonancia orbital 5:1 junto a HD 202206 b, una enana marrón con una masa de 17 veces la de Júpiter, orbitando a 0,83 UA de HD 202206, pero se comporta como un planeta. Es un planeta circumbinario, orbita a dos estrellas en lugar de una. (es) HD 202206 c adalah sebuah planet luar surya yang terletak sekitar 150,13 tahun cahaya dari Bumi. Planet ini ditemukan pada tahun 2004 dengan menggunakan metode kecepatan radial. HD 202206 c memiliki massa sebesar 17,9 massa Jupiter.

(ko) HD 202206 c é um planeta extrassolar descoberto em 16 de novembro de 2004, através da observação de longo prazo de um segunto planeta, cuja existência não era anteriormente confirmada, após a descoberta de uma anã marrom (primeira companheira) orbitando a estrela HD 202206. Este planeta perfaz sua órbita a uma distância de 3.07 vezes maior e é 7.13 vezes menos massivo que a primeira companheira, possuindo uma semi-amplitude de apenas 42 m/s. Sua massa corresponde a 2.44 planetas Júpiter e seu diâmetro se aproxima do de Júpiter. A ressonância orbital do planeta orbitando a anã marrom é de 5:1. A excentricidade do planeta é maior do que aquela de todos os planetas e planetas anões de nosso sistema solar, exceto Éris, que possui uma excentricidade de 0.44.
