SpletThe mean density of Mercury is 5.43±0.01 g cm −3 ( Anderson et al., 1987 ). This corresponds to a reduced (or uncompressed) density of 5.31 ( Kaula, 1986 ). The reduced density is the density a planet would have if it was not compressed, but was at high enough pressure to squeeze out all the pore spaces, ∼10 kbar ( Kaula, 1986 ). Splet17. feb. 2024 · If you look at my answer to the question: Mars sized planet with 83% Earth gravity? you will see I discuss this and the evolution of my thinking. In our solar system Earth has the highest density of all the planets, at 5.514 t/m $^\sf3$, then Mercury (5.427 t/m $^\sf3$), followed by Venus (5.243 t/m $^\sf3$).. Earth and Venus are what I call …

SpletThe simplest explanation for the density difference is that Mercury 's mass is about 70 % metal, compared with about 30 % for Venus and Earth. Mars has an observed density of 3.93, which converts to an uncompressed density of 3.74, distinctly less than any of the other terrestrial planets. SpletSolar System planets, can be based on the size, the mass, and the mean (or bulk) density. The radii of solar system planets can be derived from angular diameter measurements. …
