Neptune's radius in earth radii

WebMay 27, 2014 · Planets of 1–4 R ⊕ are well modeled by a rocky core containing most of the mass plus a low-density envelope, if any, that enlarges the planet’s radius. Open in viewer. By contrast, the smallest planets (1–1.5 R ⊕) all have measured densities above 5 g cm −3, consistent with interiors of rock (silicate) and iron−nickel. WebApr 13, 2024 · The innermost planet, TOI 270 b, is likely a rocky super-Earth about 25% larger than Earth. It orbits the star every 3.4 days at a distance about 13 times closer than Mercury orbits the Sun. Based on statistical studies of known exoplanets of similar size, the science team estimates TOI 270 b has a mass around 1.9 times greater than Earth’s.
