"This visualisation shows more than 500 exoplanets discovered before October 2015 (about 1/4 of all exoplanets yet discovered), arranged according to their temperature and density, showing the incredible variety of the extraterrestrial worlds.
Various known classes of exoplanets are shown on the graphic, such as Super-Earths, Hot Jupiters, Hot Neptunes, water worlds, gas dwarfs or superdense diamond planets.
All visualisations are based on the estimated radius and temperature of the planet, however other factors, such as density, age or stellar metallicity were also taken into consideration."
