This artist's concept depicts one possible appearance of the planet Kepler-452b, the first near-Earth-size world to be found in the habitable zone of a star that is similar to our sun. | NASA/JPL-Caltech/T. Pyle

This Rocky Exoplanet Is the Most Likely to Support Life

Of the thousands of known exoplanets, Kepler-452b has the most ideal combination of UV light exposure and conditions for liquid water.

This size and scale of the Kepler-452 system compared alongside the Kepler-186 system and our solar system. Kepler-186 is a miniature solar system that would fit entirely inside the orbit of Mercury. | NASA/JPL-CalTech/R. Hurt
