Interesting Facts

GJ 1214b, also known as Gliese 1214b, is 42 light years from Earth and was discovered in November 2009.

GJ 1214b is classified as a water-world, and is the only example of such a planet yet to be discovered.

Its low mass suggests that unlike Earth GJ 1214b may only have a small amount of rock in its composition.

It is thought GJ 1214b once orbited in the habitable zone around its host star, which may have allowed life to exist in its warm oceans.

GJ 1214b is now a hot world with temperatures around 200C (392F)

Despite being hot its high atmospheric pressures would stop its oceans from boiling.

Water on GJ 1214b would now have a very strange consistency and would seem very alien to us, as a result of high temperatures and atmospheric pressure it would be more like thick hot ice or alternately acting more like a gas than a liquid
