Existence once disputed Kepler-452b A world about 60% wider than Earth, circling a star very much like our Sun → Kepler-22b Twice Earth's width, in the habitable zone of a Sun-like star, and possibly covered by a single ocean → Biosignature claims disputed K2-18b A world between Earth and Neptune in size, where JWST found methane, and the most argued-about planet in the search for life → 55 Cancri e A super-Earth so close to its star that a year lasts under 18 hours, and its surface may be molten → Proxima Centauri b The nearest planet beyond the Solar System, lit by a dim red star that often flares → TRAPPIST-1 Seven Earth-sized worlds circling an ultra-cool red dwarf, all closer to it than Mercury is to the Sun → Iron rain debated WASP-76b A giant planet so hot that iron may evaporate on its dayside and fall as rain at night → TrES-2b A gas giant blacker than coal, glowing only a faint, dull red → KELT-9b A planet hotter than some stars, so hot that it is boiling away into space → Nature uncertain J1407b Rings so vast they eclipsed a star for nearly two months →
