TRAPPIST-1 g is the sixth planet from its star in the TRAPPIST-1 system, a compact group of seven rocky planets that orbit an ultracool red dwarf about 40 light-years from Earth, in the constellation Aquarius. It is the largest of the seven, slightly bigger than Earth, and it completes an orbit in just over twelve days. It lies in the habitable zone, where a planet might hold liquid water, although the surface conditions are unknown. The orbits of the planets are in resonance, with their periods related by simple ratios, a pattern that suggests the system formed far out and migrated inwards. The planets are being studied with the James Webb Space Telescope.
