Astronomers Have Found a Planet Like Earth Orbiting a Star Like the Sun

Three thousand light-years from Earth sits Kepler 160, a sun-like star that’s already thought to have three planets in its system. Now researchers think they’ve found a fourth. Planet KOI-456.04, as it’s called, appears similar to Earth in size and orbit, raising new hopes we’ve found perhaps the best candidate yet for a habitable exoplanet that resembles our home world. The new findings bolster the case for devoting more time to looking for planets orbiting stars like Kepler-160 and our sun, where there’s a better chance a planet can receive the kind of illumination that’s amenable to life.
