What is the gravitational force on each of the planets, the moon, and the sun relative to Earth? |
If the gravitational force on Earth is taken as 1, the comparative forces are:
| Sun | 27.9 |
| Mercury | 0.37 |
| Venus | 0.88 |
| Moon | 0.16 |
| Mars | 0.38 |
| Jupiter | 2.64 |
| Saturn | 1.15 |
| Uranus | 0.93 |
| Neptune | 1.22 |
Weight comparisons can be made by using this table. If a person weighed 100 pounds (45.36 kilograms) on Earth, then the weight of the person on the moon would be 16 pounds (7.26 kilograms) or 100 x 0.16.
