- Kepler-452b is an exoplanet orbiting the G-class star Kepler-452. It was identified by the Kepler space telescope and its discovery was publicly announced by NASA on 23 July 2015. It is the first near-Earth-size planet discovered orbiting within the habitable zone of a star very similar to the Sun. It is the second-most Earth-like planet known to date, after Kepler-438b, although it is not known if Kepler-452b is rocky or a small gas planet.
The star is 1,400 light-years away from the Solar System; at the speed of New Horizons, the fastest spacecraft yet launched by humanity, it would take about 25.8 million years to get there.
