Exoplanets are celestial bodies that meet the IAU's definition of a planet and orbit another star than Kerbol. Exoplanets can also be planets orbiting brown dwarf stars or planets wandering interstellar space. As of November 2016, many of the known Kopernicus packs have at least 1 exoplanet (whether it be in a separate solar system or a replacement to the Kerbol system), and a total of almost 100 exoplanets exist in the Kopernicus community. Some packs add in nothing but exoplanets. A few Kopernicus bodies that count as exoplanets are representations of real-life extrasolar worlds, some discovered by forum users (like Chantico).
