Mass-radius diagram for low mass planets showing the position of CoRoT-7b with Mp = 4.73 ± 0.95 M⊕ (Haywood et al. 2014) and the derived the radius for the selected sample, Rp = 1.585 ± 0.064 R⊕ (blue). We show the position of Earth and Venus (diamonds) for comparison. The solid lines show the mass and radius for planets with different compositions according to the models of Zeng & Sasselov (2013).
