To find what you would weigh in the gravitational field of another planet, multiply your weight on Earth times the gravitation factor listed in the table below.
Example: I weigh 90 pounds on Earth. On Mercury, I would weigh:
90 pounds X 0.38 = 34.2 pounds
On Neptune, I would weigh:
90 pounds X 1.12 = 100.8 pounds
To find your age according to the length of another planet's year, divide your age in Earth years by the period of revolution (in Earth years) of the planet listed in the table below.
Example: I am 13 Earth years old. In Mercury's orbit, I would be:
13 years ÷ 0.241 = 54 years old
In Neptune's orbit, I would be:
13 years ÷ 164.8= 0.079 years old
| Celestial Object | Gravitational Pull (Compared to Earth) | Period of Revolution (Compared to Earth) |
| Mercury | 0.38 | 0.241 Earth years |
| Venus | 0.91 | 0.615 Earth years |
| Earth | 1.0 | 1.0 Earth year |
| Mars | 0.38 | 1.88 Earth years |
| Jupiter | 2.36 | 11.9 Earth years |
| Saturn | 0.91 | 29.5 Earth years |
| Uranus | 0.89 | 84.0 Earth years |
| Neptune | 1.12 | 164.8 Earth years |
| Pluto | 0.06 (?) | 248.5 Earth years |
