9 Most Intriguing Earth-Like Planets
Earth-like Planets Kepler-438b Kepler-438b orbits a red dwarf star roughly 470 light-years from Earth. The planet is considered to be very similar to Earth in terms of radius and mass, but is likely not a habitable planet, according to astronomers. That's because, according to a 2015 study, Kepler-438b's parent star is extremely volatile, sending out "superflares" that are 10 times as powerful as anything recorded on the sun.
Confirmed small exoplanets in habitable zones (Kepler-62e, Kepler-62f, Kepler-186f, Kepler-296e, Kepler-296f, Kepler-438b, Kepler-440b, Kepler-442b).
Kepler-438b has an Earth Similarity Index of 0.88. Prior to its discovery, the two most Earth-like exoplanets known were Gliese 667Cc and Kepler-296e. This artistic rendering depicts an Earth-like exoplanet orbiting an evolved star that has formed a stunning planetary nebula; earlier in its life, this planet may have been like one of the eight newly discovered worlds orbiting in the habitable zones of their stars.
