Scientists have discovered a new Earth-like planet (行星). It is 4.2 light-years (光年) away and could be the nearest to us so far. The planet, named Proxima b, orbits (环绕运行) the star Proxima Centauri. It is not too hot and not too cold on Proxima b. It means that water could flow (流动) on its surface. The photo is an artist’s idea of what the planet looks like. TEENS |  |
