Splet24. jul. 2015 · Since gravity falls with the square of the distance, at the surface of the world, one would be x times further from the center of mass than they would be on the surface of Earth, so dividing the x 3 by x 2, gives us x times earth gravity at the surface of the alien world. Thus, all other things being equal, gravity seems to scale linearly with ... 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. SpletRemember, the volume of a spherical planet is equal to 4.19 r 3, and the density is equal to the mass divided by the volume. You learned about planet densities in Week 2.
