Discovered in 2012 by astronomers from CFHT and VLT, this rogue body was found in the AB Doradus moving group (ABDMG) at about 100 l.y. With a mass between 4-15 Mj and a surface temperature below 100°C, this body can be a rogue jovian-like exoplanet or more probably a very young and small dwarf brown star of T type (Tp < 900°C). Its atmosphere contains methane and water.

Alpha Centauri is a triple star system including a G2 star (A) of 1.09 Ms around which orbit a K1 star (B)of 0.9 Ms escorted by an exoplanet of 1.13 earth-mass at a distance of 6 million km only with a revolution in 3.24 days. Proxima Centauri, a red dward of M5 class and 0.1 Ms orbits at 13000 AU of star A.

GJ1214b is about 2.7 times Earth’s diameter and weighs almost seven times as much. It orbits a red-dwarf star every 38 hours at a distance of 2 million kilometres, giving it an estimated temperature of 230 degrees Celsius. It orbits in 38 hours at 2 million km around a red dwarf star of class M4.5 GJ1214b is about 2.7 times Earth’s diameter and weighs almost seven times as much. It orbits a red-dwarf star every 38 hours at a distance of 2 million kilometres, giving it an estimated temperature of 230 degrees Celsius.
