Scientists have found a new planet like Earth in the universe, the nearest so far. The planet is named Proxima b. It is 4.2 light-years away from Earth. Like Earth orbits (围绕运行) the sun, Proxima b orbits the star Proxima Centauri. It is not too hot and not too cold on Proxima b. So scientists think there could be liquid water (液态水) on it. In the photo is an artist’s idea of what Proxima b looks like. TEENS
