NotesOne of the seven Earth-mass planets that orbit the cool red dwarf star TRAPPIST-1 in Aquarius, some 41 light years from the Sun. Of these planets, only TRAPPIST-1 h orbits farther from the star than TRAPPIST-1 g, but all seven planets follow very close orbits around TRAPPIST-1, and TRAPPIST-1 g completes each circuit of the star in a period of a little over twelve days.
