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 potentially rocky super-Earth planet discovered orbiting within the habitable zone of a star very similar to the Sun. Using the criteria of the Earth Similarity Index, it is the sixth-most Earth-like exoplanet known to date. The planet is about 1,400 light-years away from the Solar System; at the speed of the New Horizons spacecraft, about 59,000 km/h (37,000 mph), it would take approximately 26 million years to get there.
