ExoPlanets: GJ 15 A c by 𝙽𝙵𝚃 𝙿𝚑𝚘𝚎𝚗𝚒𝚡

GJ 15 A c is a gas giant 36 times the mass of Earth, and appears to have roughly a 20-year orbit around its cool and small parent star. While its temperature is not known, it's likely to be quite cold in this distant, possibly icy orbit, loosely comparable to the orbit of Saturn around our Sun.
