NASA's Kepler Mission Discovers Kepler-16b, A Planet Orbiting Two Suns
Kepler-452b is an exoplanet orbiting the Sun-like star Kepler-452 about 1,400 light-years from Earth in the constellation Cygnus. It was identified by the Kepler space telescope, and its discovery was announced by NASA. However, a study in 2018 by Mullally et al. implied that statistically, Kepler-452 b has not been proven to exist and must still be considered a candidate.
