TRAPPIST-1 b is the innermost of seven Earth-sized planets orbiting TRAPPIST-1, an ultracool red dwarf about 40 light-years away in Aquarius. It was found by astronomers using the TRAPPIST telescopes in Chile and Morocco, which detected it passing in front of its star, together with two other planets, in a discovery published in Nature. The planet orbits in only about a day and a half and is probably very hot. Observations by the James Webb Space Telescope measured the heat from its day side and indicated that it has little or no thick atmosphere. This was an important test of whether rocky planets around such small stars can keep an atmosphere.
