Escape Velocity Calculator
Compute the minimum speed needed for an object to escape a celestial body's gravitational pull.
CalcSimpler Examples
- Earth ⇒ 11,186 m/s
- Moon ⇒ 2,376 m/s
- Mars ⇒ 5,027 m/s
FAQ
What is escape velocity?
The speed needed to break free from a body's gravity without further propulsion.
Does rotation matter?
This simple model ignores planetary rotation and atmosphere.
Additional Information
- Calculated using Newton's law of universal gravitation and assumes no atmospheric drag.
- Escape velocity decreases with altitude as distance from the center increases.
- Real spacecraft reach escape speed gradually through sustained propulsion, not an instant burst.
- Using precise planetary mass and radius values improves accuracy for specific bodies.
