“The TRAPPIST-1 system, located about 41 light-years away, is the richest single laboratory for studying temperate terrestrial planets, hosting seven roughly Earth-sized planets, of which several lie in or near the habitable zone. Planets d, e, and f are the most-discussed habitable-zone members, with e generally considered the most likely to sustain surface liquid water given an appropriate atmosphere. The system's value comes from its…”
