Exoplanete Gliese 1214 b - Gliese 1214 b (or GJ 1214 b) is a super-Earth exoplanet orbiting the star Gliese 1214 in the constellation Ophiuchus, whose discovery was announced on 16 December 2009. It is located about 40 years from the Sun. It is the third discovered exoplanet whose size is smaller than that of a gas giant and the first on which water could be present in large quantities given its size and estimated mass. It could be the first ocean planet discovered. Gliese 1214 b is an extrasolar planet that orbits the star Gliese 1214. The parent star is 13 parsecs (approximately 40 light - years) from the Sun, in the constellation Ophiuchus. The planet was discovered in December 2009. It is classified as a super - Earth because it is larger than Earth but has a mass and radius significantly less than those of the gas giants in the Solar System. After COROT - 7b, it is the second such planet to be known and is the first of a new class of planets with small size and relatively low density
