Kepler-452b (a planet sometimes quoted to be an Earth 2.0 or Earth's Cousin.
based on its characteristics; also known by its Kepler Object of Interest DESIGNATION KOI-7016.01) is an exoplanet orbiting the Sun-like star Kepler-452 about 1,402 light-years (430 PC) from Earth in the constellation Cygnus. 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.
