Unlike Newtonian Physics where mass is so important, other factors such as rotation, orbital speed, and distance from sun are important in understanding the gravity of different planets.
| Name | Gravity Speed in m/s2 | Diameter in km | Density in g/cm3 |
|---|---|---|---|
| Ceres | 0.27 (3% of earth) | 940 | 2.2 |
| Earth | 9.81 | 12,742 | 5.5 |
| Jupiter | 23.1 | 142,800 | 1.3 |
