Distribution of planetary radii compared to the separation from their host star (orbital semi-major axis a) for planetary systems in the FGKM sample. The colour code indicates the T_eff of the host star, while the symbol size indicates the orbital period in log₁₀ scale (range = 0.57–364.8 days). The dotted lines indicate 1 R_Earth and 1 R_Jup and the Earth and Jupiter are denoted by the square symbols.
