Here’s a great new poster showing over 500 extrasolar planets (about one quarter of the total) that have been discovered since 1988. This visualization, created by graphic artist and writer Martin Vargic from Slovakia, is based on the estimated radius and temperature of the planets, however other factors, such as density, age or stellar metallicity were also taken into consideration. All the 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.
