Kepler-452b (whiles nicknamed Yird 2.0 or Yird's Cousin[6][7] based on its chairacteristics; kent whiles as Coruscant bi NASA,[8] an aa kent bi its Kepler Object o Interest designation KOI-7016.01) is an exoplanet orbitin the Sun-lik starn Kepler-452 aboot 1,400 light-years (430 pc) frae Yird in the constellation Cygnus. It wis identified bi the Kepler space telescope, an its discovery wis annoonced bi NASA on 23 Julie 2015.[2] It is the first potentially rocky super-Yird[4] planet discovered orbitin within the habitable zone o a starn very seemilar tae the Sun.[9]
