Kepler-25b is an extrasolar planet orbiting the star Kepler-25, located in the constellation Cygnus.[5] It was discovered by the Kepler Space Telescope in 2012. Kepler-25b is one of the most massive planets ever found. if it had the equivalent of 1 extra Saturn mass, it would be considered a brown dwarf, as it has ≈12,7 Jupiter Masses. ≥13 Jupiter Masses is required for deuterium fusion.
