Weight on Other Planets Calculator

About the Weight on Other Planets Calculator

Your weight depends on the gravitational pull of the body you are standing on. While your mass stays the same everywhere, your weight — the force of gravity on your mass — changes dramatically across the solar system. On the Moon you would weigh only 16.5% of your Earth weight, while on Jupiter you would feel 2.5 times heavier.

Surface gravity depends on both a body's mass and its radius. Jupiter is 318 times more massive than Earth but its much larger radius means surface gravity is "only" 2.53 times Earth's. Conversely, a dense but small body like Io has surface gravity similar to the Moon despite being larger.

This calculator computes your weight on 15 bodies including all eight planets, the Moon, Pluto, and major moons like Europa, Titan, and Ganymede. It also estimates how high you could jump on each body based on your Earth jump height, provides a visual gravity comparison chart, and displays detailed planetary data for reference.

When This Page Helps

This calculator is useful whenever you want a quick, concrete comparison of how gravity changes your weight on different worlds. It also helps explain why low-gravity bodies make jumping easier and why massive planets like Jupiter feel so different from Earth even when they are made of the same kinds of materials.

How to Use the Inputs

1. Enter your weight or mass in kilograms, pounds, or Newtons.
2. Enter your jump height on Earth in meters (average is 0.5 m).
3. Select a body to highlight in the comparison chart.
4. Use preset buttons for common weights.
5. Review your weight and jump height on all 15 solar system bodies.
6. Explore the gravity comparison chart and planetary data tables.

Example Calculation

Tips & Best Practices

• Your mass in kg is the same as your weight in kgf on Earth (numerically).
• Jupiter's gravity would make it extremely difficult to stand up.
• On the Moon, you could jump about 6× higher than on Earth.
• Weight on a body depends on both its mass and radius.
• Ceres (the largest asteroid) has the lowest gravity in our list at 0.28 m/s².

Gravity And Weight

Weight is a force, so it changes with surface gravity even when mass stays the same. That is why the same person can feel light on the Moon and much heavier on Jupiter.

Why The Results Differ

A body with more mass does not always produce stronger surface gravity. Radius matters too, because gravity falls with the square of distance from the center. Large, low-density worlds can have gravity that is less dramatic than their size suggests.

Using The Jump Estimate

The jump-height estimate assumes the same takeoff effort. It is a simple way to visualize how lower gravity affects movement, but it does not account for atmosphere, terrain, or suit mass.

Frequently Asked Questions

• What is the difference between weight and mass?

  Mass is the amount of matter in an object (measured in kg) and is constant everywhere. Weight is the gravitational force on that mass (measured in Newtons or kgf) and changes depending on surface gravity.

• Which planet has the strongest gravity?

  Jupiter, with surface gravity of 24.79 m/s² (2.53 times Earth). Among rocky planets, Earth has the strongest gravity.

• How much would I weigh on the Moon?

  About 16.5% of your Earth weight. A 70 kg person would weigh about 11.6 kgf on the Moon.

• Could I jump higher on Mars?

  Yes — about 2.6 times higher. Mars gravity is 38% of Earth's, so the same leg force produces a higher jump.

• Why is Pluto included — is it a planet?

  Pluto is classified as a dwarf planet since 2006. We include it because it remains a popular target of curiosity, and its extremely low gravity (0.62 m/s²) provides an interesting comparison.

• Do astronauts on the ISS weigh zero?

  No — they are in freefall (constantly falling around Earth), creating the sensation of weightlessness. Actual gravity at ISS altitude (~400 km) is still about 89% of surface gravity.
