A Planemo or Super Jupiter 4 times Jupiter's mass orbiting a brown dwarf 172 ly away. The planemo is possibly the first "planet" imaged and orbits 40 AU. A disk around the Brown Dwarf was known, but recently a disk around the Planemo was also detected. It is believed to be glowing hot from a recent collision with a Uranus sized planet. The planemo probably didn't form the way planets do, but rather, in the same manner as binary stars do. It is only 10 MYO and still contracting and radiating heat. Its cloud top temperature is above 2000F, making it possible rock and iron rain might form. Its rotational period is estimated to be around 11 hours, about the same as Jupiter.
