NASA’s space observatory Kepler may have discovered a new Earth-like planet, a rocky world orbiting a Sun-like star at almost the exact same distance Earth orbits our own Sun: Kepler 452b! Here is an artist’s impression of exoplanet Kepler-452b, which is likely to be rocky, just as Earth is. SETI Institute/Danielle Futselaar.
Kepler-452b is an exoplanet orbiting the Sun-like star Kepler-452 about 1,400 light-years (430 pc) from Earth in the constellation Cygnus. It sometimes quoted to be an Earth 2.0 or Earth’s Cousin based on its characteristics; known sometimes as Coruscant by NASA, also known by its Kepler Object of Interest designation KOI-7016.01. It was identified by the Kepler space telescope, and its discovery was announced by NASA on 23 July 2015. However, a study in 2018 by Mullally et al. implied that statistically, Kepler-452b has not been proven to exist and must still be considered a candidate. It is the first potentially rocky super-Earth planet discovered orbiting within the habitable zone of a star very similar to the Sun.
