1. What is the Weight on Planets Calculator?

The Weight on Planets Calculator estimates how much you would weigh on different planets in our solar system based on your weight on Earth and the surface gravity of each planet.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( weight_p \) — Weight on planet (N)
• \( weight_e \) — Weight on Earth (N)
• \( g_p \) — Gravity of the planet (m/s²)
• \( g_e \) — Earth's gravity (9.81 m/s²)

Explanation: Your weight changes on different planets because the force of gravity varies depending on the planet's mass and size.

3. Importance of Planetary Weight Calculation

Details: Understanding how weight varies across planets helps in space mission planning, scientific education, and satisfying general curiosity about our solar system.

4. Using the Calculator

Tips: Enter your weight on Earth in newtons (N), select a planet from the dropdown menu, and click calculate. All values must be valid (weight > 0).

5. Frequently Asked Questions (FAQ)

Q1: Why does weight change on different planets?
A: Weight is the force of gravity acting on your mass. Since planets have different masses and sizes, their gravitational pull differs.

Q2: Does my mass change on different planets?
A: No, your mass stays the same. Only the force of gravity (weight) changes based on the planet's gravity.

Q3: Why is Earth's gravity 9.81 m/s²?
A: This value is determined by Earth's mass and radius. It's the acceleration due to gravity at Earth's surface.

Q4: Which planet has the strongest gravity?
A: Jupiter has the strongest surface gravity in our solar system at 24.79 m/s² (about 2.5 times Earth's gravity).

Q5: Can I use this for moons or other celestial bodies?
A: The same formula works, but you would need to know the surface gravity of the specific moon or celestial body.
