Description: TRAPPIST-1, also designated 2MASS J23062928-0502285,[9] is an ultra-cool red dwarf star[10][11] that is slightly larger, but much more massive, than the planet Jupiter; it is located 39.6 light-years (12.1 pc) from the Sun in the constellation Aquarius.[12][13] Seven temperate terrestrial planets have been detected orbiting the star, a larger number than detected in any other planetary system.[14][15] A study released in May 2017 suggests that the stability of the system is not particularly surprising if one considers how the planets migrated to their present orbits through a protoplanetary disk.
