Gliese 436 b was discovered in August 2004 by the planet-hunting-by-way-of-radial-velocity team of Dr.Paul Butler and Geoffrey Marcy of the Carnegie Institute of Washington and University of California, Berkeley, respectively. Unlike the ice on Earth, which is put into a solid state due to temperature, the ice on Gliese 436 b is in a solid state simply due to pressure. It has been determined that the world is made mostly of water so the high temperatures would make the atmosphere mostly steam but the higher pressures further down would compress the water into a super heated but solid state called "hot ice". The planet is about 4000 km larger in diameter than Uranus and 5000 km larger than Neptune and a bit more massive.
