It is possible there are other planets, slightly further from the star, that have yet to be discovered by astronomers, but they are likely too far away for liquid water to form. To illustrate what this means from our perspective: the Voyager 1 spacecraft is currently travelling away from Earth at a speed of The Planetary Science Journal Tag: Science. It was discovered by the Scottish astronomer Robert Innes in Except… in August astronomers announced they had confirmed the presence of a planet orbiting the diminutive star , and moreover it's very roughly the same mass as Earth , orbiting Proxima in its habitable zone.
