Weight on Other Planets Calculator
Have you ever wondered how much you would weigh on Mars, the Moon, or Jupiter? This calculator lets you instantly compare your Earth weight across planets, moons, stars, and even extreme cosmic objects like neutron stars and black holes.
Enter your Earth weight and see how much you would weigh on planets, moons, and extreme space objects.
How Weight Changes on Different Planets
Your mass stays the same everywhere in the universe, but your weight changes depending on gravity. Every planet, moon, or star has a different gravitational pull.
For example:
- The Moon has weak gravity, so you would weigh much less there.
- Jupiter has very strong gravity, so you would weigh much more.
- Mars has lower gravity than Earth, making movement feel lighter.
This is why astronauts can jump higher on the Moon than on Earth.
Why Gravity Changes Your Weight
Weight is created by gravity pulling on your body. Stronger gravity increases your weight, while weaker gravity reduces it.
The calculator uses Earth’s gravity as the reference point and compares it with:
Some objects, such as neutron stars and black holes, are included for scientific comparison and imagination only because humans could not survive there.
Weight on the Moon vs Earth
The Moon’s gravity is only about 16.5% of Earth’s gravity. That means if you weigh:
- 100 kg on Earth
- You would weigh only about 16.5 kg on the Moon
This weaker gravity allowed Apollo astronauts to move differently during lunar missions.
Weight on Mars
Mars has about 38% of Earth’s gravity. Many people are curious about Mars because future human missions may eventually travel there.
If you weigh:
- 70 kg on Earth
- You would weigh about 26.6 kg on Mars
You would still have the same body mass, but you would feel much lighter.
Weight on Jupiter
Jupiter is the largest planet in the Solar System and has much stronger gravity than Earth.
If you weigh:
- 70 kg on Earth
- You could weigh more than 160 kg on Jupiter
The stronger gravitational pull would make movement far more difficult.
Weight on Extreme Space Objects
This calculator also includes scientific comparisons for objects with extreme gravity:
White Dwarf Star
A white dwarf is an incredibly dense leftover core of a dead star. Gravity there is extremely powerful.
Neutron Star
Neutron stars are among the densest known objects in the universe. Their gravity is billions of times stronger than Earth’s.
Black Hole
Near a black hole, gravity becomes so intense that even light cannot escape. The values shown are simplified educational comparisons.
Frequently Asked Questions
Does my weight really change on other planets?
Yes. Your weight changes because each planet has different gravity. However, your mass stays the same everywhere.
Why do I weigh less on the Moon?
The Moon has much weaker gravity than Earth. That is why astronauts could jump higher and move more slowly during Moon missions.
Which planet would make me weigh the most?
Jupiter would make you weigh the most because it has the strongest gravity among the planets in this calculator.
Which place would make me weigh the least?
Pluto and the Moon would make you feel much lighter than Earth because their gravity is very weak.
Is weight the same as mass?
No. Mass is how much matter your body contains. Weight is the force of gravity pulling on that mass.
Can I use pounds instead of kilograms?
Yes. The calculator supports both kilograms and pounds, so users from different countries can easily compare their weight.
Can humans survive on a neutron star or near a black hole?
No. Neutron stars and black holes have extreme gravity. They are included only for scientific comparison and imagination.
Why is Jupiter’s gravity so strong?
Jupiter is the largest planet in the Solar System. Its huge mass creates a much stronger gravitational pull than Earth.
