25th Jul 2015: A Spin Around An Exoplanet Most Like Earth

This artistic animation depicts one possible appearance of the planet Kepler-452b, the first near-Earth-size world to be found in the habitable zone of star that is similar to our sun. The star, Kepler-452, is a G2-type star like our sun, with nearly the same temperature and mass. The planet's rotation is sped up.
