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-1d is an Earth-sized exoplanet orbiting the TRAPPIST-1 star. It resides within the system's habitable zone, raising possibilities for liquid water on its surface. The planet’s rocky composition and size make it a subject of interest for astronomers studying potentially habitable worlds beyo...

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 an Earth-sized exoplanet orbiting the TRAPPIST-1 star. It’s notable as the most distant planet in this system and a key target for studying potentially habitable environments. Scientists investigate its atmospheric conditions and temperature to assess whether it could sustain liquid w...

TOI-700 d is an Earth-sized exoplanet discovered in 2020 using data from NASA's Transiting Exoplanet Survey Satellite (TESS). It orbits a nearby red dwarf star within its conservative habitable zone, a region where liquid water could theoretically exist on the surface. The planet is tidally locked t...

Kepler-20f is a near-Earth-sized exoplanet orbiting the sun-like star Kepler-20, located approximately 929 light-years from Earth in the constellation Lyra. Confirmed alongside Kepler-20e in December 2011 by NASA's Kepler space telescope, the planet has a radius roughly 1.03 times that of Earth, mak...

Kepler-20e is an extrasolar planet orbiting the sun-like star Kepler-20, located approximately 950 light-years away from Earth. Detected by NASA's Kepler space telescope, its discovery was officially confirmed in December 2011, marking it as one of the first identified Earth-sized exoplanets. The pl...

TOI-700 e is an Earth-sized exoplanet orbiting TOI-700, an M-dwarf star approximately 100 light-years from Earth in the constellation Dorado. It was identified using data from NASA's Transiting Exoplanet Survey Satellite (TESS) and announced in January 2023. The planet orbits within the star's habit...

Announced in 2019, HD 21749 c is an Earth-sized exoplanet discovered by NASA's TESS satellite, notable for being the first roughly Earth-sized planet found by the TESS mission.

TOI-700 b is an Earth-sized exoplanet discovered by NASA's TESS satellite in 2020, notable for being the innermost planet in a multi-planet system orbiting within a red dwarf star.
