Illustration of the hot rocky exoplanet TRAPPIST-1 b, the innermost of seven known planets in the TRAPPIST-1 system. TRAPPIST-1 b is slightly larger than Earth, but has around the same density, which indicates that it must have a rocky composition. The star, TRAPPIST-1, is an ultracool red dwarf (M dwarf).
