Planet mass–radius diagram. We present two newly discovered planets from the WASP survey for transiting planets, WASP-65b (red-filled square), and WASP-75b (blue-filled square). The grey points represent the known exoplanets in the Saturn and Jupiter mass regimes taken from exoplanet.org (23 May 2013) and complemented from the literature. Saturn and Jupiter are marked in the green-filled triangles, and are initialed. The continuous (cyan) lines represent equal density traces of 0.1, 0.5, 1.0, and 2.0 ρ_J, from left to right. WASP-65b lies in between the lower-density giant planets and the higher-density high-mass planets.
