Gliese  180 (often shortened to GJ 180), is a red dwarf star, known to have two planets Gliese 180 b and Gliese 180 c. It is located approximately 40 light-years away from Earth.

According to the Planetary Habitability Laboratory (PHL) in Puerto Rico, both worlds in the system may be classifiable as potentially habitable planets. Planet Gliese 180 b and Gliese 180 c have masses of 6.4 and 8.3 Earth masses, respectively. However, Dr Mikko Tuomi, of the UK’s University of Hertfordshire, whose team identified the planets, disagreed, stating:

"The PHL adds some sort of an “extended HZ”, which I, frankly, do not know how it’s calculated, but that adds some areas of potential habitability to the inner and outer edges of the HZ as we have defined it. They included the inner companion of the GJ 180 system (planet b) that we consider too hot to be potentially habitable.”
