GJ 1132 b

(Gliese 1132 b)
(Earth-like extrasolar planet discovered in 2015)

GJ 1132 b (Gliese 1132 b) is an Extra Solar Planet orbiting star GJ 1132 (Gliese 1132), 12 Parsecs from Earth, and somewhat close to Earth-size, i.e., 1.6 Earth-masses and 1.2 Earth radius. It is a Transiting Planet detected by the MEarth Project. It was discovered in 2015.

It is of interest for sufficiently close to observe, and though not in the Habitable Zone, still cool enough (410 K) to retain an Atmosphere, which can be investigated using Transmission Spectroscopy.
