Escape velocity formula calculator

Escape velocity formula calculator allows you to calculate escape velocity of an object, it need to free from the gravitational field of a planet in the solar system, or massive body with defined mass and radius.

Select a planet or enter mass and radius

  
Planet:
Escape velocity of Earth
Escape velocity (second cosmic velocity) is the minimum speed needed for an object to escape from the gravitational field of a planet or a massive body.
where M - mass of the planet, R - radius of the planet, G - Universal Gravitational Constant = 6.67408 x 10-11N*m2/kg2
