Kepler-20f. Computer artwork of the extrasolar planet Kepler-20f,which orbits the class G8 star Kepler-20 (not shown),around 950 light years from Earth. This planet is part of a system that contains four other planets all circling within a distance roughly equal to Mercury's orbit in our solar system. Kepler-20f is the closest object to the Earth in terms of size ever discovered,but with a surface temperature of 430 degrees Celsius it is too hot to host like as we know it | |
