Abstract

We report on the discovery and validation of Kepler-452b, a transiting planet identified by a search through the 4 years of data collected by NASA s Kepler Mission. This possibly rocky $1.63 _ -0.20^+ 0.23 $ $R _ \ oplus $ planet orbits its G2 host star every $384.843 _ -0.012^+ 0.007 $ days, the longest orbital period for a small ($R _ \ rm P\ lt 2$ $R _ \ oplus $) transiting exoplanet to date. The likelihood that this planet has a rocky composition lies between 49% and 62%. The star has an effective ...
