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...
Kepler-186f is an exoplanet approximately Earth-sized orbiting the red dwarf star Kepler-186. It resides within its star’s habitable zone, meaning liquid water could potentially exist on its surface. This makes it notable as one of the first discovered planets similar in size to Earth and residing i...
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...
Kepler-1649c is an exoplanet roughly Earth-sized orbiting a red dwarf star named Kepler-1649. Its location within its star’s habitable zone—the region where liquid water could exist on the surface—makes it notable. Scientists study this super-Earth to assess the potential for habitability around M-d...
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 an Earth-sized exoplanet orbiting the ultra compact M-dwarf star TRAPPIST-1. Located 39 light-years from Earth, it’s notable as the closest planet to our solar system and one of seven similar-sized planets in a tightly packed arrangement. Scientists study this transiting planet to und...
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.
TOI-700 d is an Earth-sized exoplanet discovered by NASA's TESS satellite in 2020, notable for being one of the few potentially habitable worlds located in its star's habitable zone.
A near-Earth-sized planet in the Kepler-20 system confirmed alongside Kepler-20e in December 2011, with a radius slightly exceeding Earth's at approximately 1.03 Earth radii.
