Understanding Space Gravity
Your weight varies across planets due to differences in gravitational acceleration. This force depends on both the planet's mass and your distance from its center. While your mass remains constant, weight (mass × gravity) changes with location.
How Gravity Affects Your Weight
Weight varies by planet due to different gravitational forces. For example, you weigh less on the Moon and more on Jupiter. Gravity is calculated using the formula: Weight = Mass × Gravitational Acceleration.
Gravity Comparison Table
| Planet | Gravity (m/s²) | vs Earth |
|---|---|---|
| Mercury | 3.7 | 0.38× |
| Venus | 8.87 | 0.9× |
| Earth | 9.81 | 1× |
| Mars | 3.71 | 0.38× |
| Jupiter | 24.79 | 2.53× |
| Saturn | 10.44 | 1.06× |
| Uranus | 8.87 | 0.9× |
| Neptune | 11.15 | 1.14× |
| Earth's Moon | 1.62 | 0.17× |
| Pluto | 0.62 | 0.06× |
Frequently Asked Questions
Why does weight change on different planets?
Weight depends on gravitational force, which varies based on a planet's mass and size. Larger planets with more mass exert stronger gravitational pull.
Is this calculator accurate for moons?
This calculator focuses on planets. Moon gravity differs significantly (Earth's Moon: 1.62 m/s²). We'll add moon calculations in future updates!
How is this different from mass?
Mass measures matter quantity (constant everywhere), while weight measures gravitational force (changes with location).
Can humans survive Jupiter's gravity?
Jupiter's intense gravity (2.5× Earth's) would make movement extremely difficult and could cause cardiovascular strain for humans.
Why is Pluto included even though it's not a planet?
While Pluto is classified as a dwarf planet, we include it due to popular interest. Its gravity (0.62 m/s²) makes it an interesting comparison - you'd weigh just 6% of your Earth weight!
Can I calculate weight for other moons?
Our calculator currently focuses on Earth's Moon. Other moons like Titan (Saturn) or Europa (Jupiter) have different gravity values and may be added in future updates.
