Plots of exoplanet density and radius. Top: Density vs. Radius. Bottom: Diffusity=1/Density vs. Radius. Units: Radius in Jupiter radii (RJup). Density
Plots of exoplanet density and radius. Top: Density vs. Radius. Bottom: Diffusity=1/Density vs. Radius. Units: Radius in Jupiter radii (RJup). Density in g/cm3. Diffusity in cm3/g. These plots show that there are a wide range of densities for planets between Earth and Neptune size, then the planets of 0.6 RJup size are very low-density and there are very few of them, then the gas giants have a large range of densities.

An exoplanet or extrasolar planet is a planet outside the Solar System. The first confirmed detection of an exoplanet was in 1992 around a pulsar, and the first detection around a main-sequence star w
