Escape Velocity Calculator for Jupiter
Estimate the escape velocity from the cloud tops of Jupiter using its mass and mean radius.
Calculate the escape velocity required for an object to break free from a celestial body's gravitational pull. Enter your Mass of the Celestial Body (M), Radius from Center of Mass (R) to get an instant escape velocity (m/s). Formula: sqrt((2 * 6.67430e-11 * m) / r).

How It Works
How It Works
This calculator finds the minimum speed needed for an object to completely escape a planet’s gravity without any further thrust. It uses a standard physics formula based on the planet’s mass and the distance from its center.
The formula calculates how strongly gravity pulls on an object and determines the speed required to overcome that pull. A more massive planet increases the escape velocity, while a larger radius decreases it.
- Uses the formula: sqrt((2 × G × M) / R)
- G is the gravitational constant (6.67430 × 10⁻¹¹)
- M is the mass of the planet in kilograms
- R is the distance from the planet’s center in meters
- Returns escape velocity in meters per second (m/s)
Understanding the Results
The result tells you the minimum speed an object must have to break free from gravity without falling back. If the object moves slower than this speed, gravity will eventually pull it back down.
Higher escape velocities mean stronger gravity. For example, larger and denser planets require much greater speeds to escape compared to smaller bodies like the Moon.
- Higher mass increases escape velocity
- Greater radius lowers escape velocity
- The value is measured in meters per second (m/s)
- No additional propulsion is needed once this speed is reached
- Applies to rockets, asteroids, or any object leaving the surface
Frequently Asked Questions
What is escape velocity?
Escape velocity is the minimum speed an object must reach to break free from a planet or celestial body's gravitational pull without any additional propulsion. Once this speed is achieved, the object will continue moving away indefinitely, assuming no other forces act on it. It does not depend on the object's mass.
When should I use this escape velocity calculator?
Use this calculator when you want to determine how fast an object must travel to escape the gravity of a planet, moon, or other celestial body. It is commonly used in physics problems, astronomy studies, and space mission planning. Simply enter the body's mass and the radius from its center.
What values should I enter for mass and radius?
Enter the total mass (M) of the celestial body in kilograms and the distance (R) from the center of mass in meters. For example, for Earth, use approximately 5.972 × 10^24 kg for mass and 6.371 × 10^6 meters for radius. Make sure both values are in the correct units for accurate results.
Does the mass of the escaping object affect the result?
No, the mass of the object escaping does not affect escape velocity. The formula depends only on the gravitational constant, the mass of the celestial body, and the distance from its center. This means a rocket and a small rock would require the same escape velocity from the same location.
Why does increasing the planet’s mass increase escape velocity?
A more massive planet has a stronger gravitational pull, which requires a higher speed to overcome. Since escape velocity is proportional to the square root of the planet’s mass, doubling the mass increases the escape velocity, but not by double—only by the square root of 2.
How does distance from the center affect escape velocity?
Escape velocity decreases as the distance from the center of mass increases. This means it takes less speed to escape from higher altitudes than from the surface. For example, spacecraft in orbit require less additional speed to escape Earth's gravity than objects launched directly from the surface.
