Photos: A look at NASA's discovery of Earth 2.0

Kepler solar system

Kepler-452b orbits a star that is much like the Sun and resides in the Kepler-186 solar system. The planet itself is about "60% larger than Earth, with a surface gravity 2x that of Earth, and a slightly better than even chance of being a rocky planet, with an atmosphere likely thicker than Earth's, and possibly with active volcanoes," states NASA. It has a 385 day orbit, which means it's a distance from its main star that is suitable for the existence of liquid water as well.
