This escape velocity calculator allows you to determine the minimum velocity for an object in order to escape gravitation on any planet using mass and radius. You can discover more information on the subject below the form.


Instruction: Please input only two fields from the three below!

Planet mass:*
Planet radius:*
Escape velocity:*

How does this escape velocity calculator work?

This is a useful tool for all those interested to compute escape velocity based on planet mass and radius or even discover any of these two by knowing the other one and the escape velocity value.

The escape velocity calculator allows you to choose from a series of measurement units for your convenience as well. And you can input any two of the three components of the escape velocity formula to retrieve the third.

Here is the formula used:

V = square root of 2*G*M/R  

Where

V represents escape velocity in m/s

M represents planet mass in kg

R represents planet radius in m

G is a constant: universal gravitational value = 6.6726 × 10-11 Nm2/kg2

What is escape velocity?

This is the speed that an object needs to reach in order to escape from the gravitational pull of a planet without any other propulsion. The kinetic energy in this case should be equal in magnitude with potential energy and there should be no friction resistance for the escape to be possible.
