Oct 15, 2003 #4 Phobos Staff Emeritus Science Advisor Gold Member 1,939 6 Gravity dictates the orbits of the planets around the sun (and as Janus said, the moons around the planets). By measuring those orbits, you can calculate the planet's gravity. See the link I provided in the other topic you started.
