Relations between the spectral type of main-sequence stars (represented by effective temperatures) and the innermost orbital distance for a rocky planet to stay unmelted. Red dots are Kepler-released planet candidates as of April 2011 (Borucki et al. 2011). From left to right, the black markers correspond to planets that have or may have rocky surfaces: 55 Cnc e, Kepler-10 b, Corot-7 b, Kepler-18 b, Kepler-20 e, Kepler-11 b, Kepler-20 f, Mercury, Kepler-22 b and Earth.
