TRAPPIST-1e is an Earth-sized exoplanet orbiting the ultra-cool dwarf star TRAPPIST-1. Its location within the habitable zone—the region around a star where liquid water could exist on a planet’s surface—makes it notable. Scientists study this world to assess its potential for hosting conditions sui...
TRAPPIST-1f is an Earth-sized exoplanet orbiting the TRAPPIST-1 star. It resides within the habitable zone where liquid water could exist on its surface. Its larger size and lower stellar flux compared to our Sun may result in significant ice coverage. Scientists study this planet for potential sign...
TRAPPIST-1g is an Earth-sized exoplanet orbiting the TRAPPIST-1 star. Its notable size, approximately 1.13 times that of Earth, and location within the habitable zone make it a key target in the search for potentially life-supporting worlds. Scientists study this rocky planet to assess its atmospher...
TRAPPIST-1c is an Earth-sized exoplanet orbiting the ultracool dwarf star TRAPPIST-1. Located within the TRAPPIST system, it’s notable for its potential habitability due to its size and proximity to its star. The planet transits its star regularly making it a target for atmospheric study. Scientists...
TRAPPIST-1b is the innermost of seven Earth-sized planets in the TRAPPIST-1 system 39 light-years away, first announced in 2016; its tight orbit renders it far too hot for liquid water.
TRAPPIST-1h is the outermost of the seven TRAPPIST-1 planets, announced in 2017; it likely receives insufficient stellar flux for liquid surface water without a strong greenhouse effect.
