Insert the information in the form and the calculator will determine the escape velocity.

What is the escape velocity?

Escape velocity is the speed at which an object travels to break free either the planet's or moon's gravity and leave without any development of propulsion.

How to calculate escape velocity?

To calculate escape velocity you should use the following formula:
ve = √((2 * G * M) / r)
where:
ve = escape velocity
G = universal grevitational constant
M = mass of the body to be escaped from
r = distance from the center of the mass

Why use escape velocity?

The escape velocity is used in order to determine the speed at which the object should travel to break free from the planet's or moon's gravity.
