Above, we see KOI 172.02, the most Earth-like planet found yet, and it’s actually about 1.5 times bigger than our blue planet, so it’s classed as a ’super-Earth‘. The planet is also following an orbit that is well within the habitable zone of a star that is rather similar to our Sun – means that the planet could feature liquid water and potentially oceans on its surface
