Escape Velocity Calculator

Formula : Ve = 2GMR 

Universal Gravitational Constant(G) = 6.6726 * 1011 Nm2/kg2

Enter the unknown value as ‘ x ‘

Escape Velocity(ve)= m/s
Planet Mass(M) = kg
Planet Radius(R) = m

x =


Escape Velocity Calculator is a free online tool that displays the escape velocity of the object. BYJU’S online escape velocity calculator tool makes the calculation faster and it displays the escape velocity of the object from the gravitational attraction in a fraction of seconds.

How to Use the Escape Velocity Calculator? 

The procedure to use the escape velocity calculator is as follows:

Step 1: Enter the planet mass, radius and x for the unknown in the input field

Step 2: Now click the button “Calculate the Unknown” to get the escape velocity

Step 3: Finally, the escape velocity of the object from the gravitational attraction will be displayed in the output field

What is Meant by the Escape Velocity?

In Physics, the escape velocity is defined as the minimum velocity or speed required to leave a planet or the moon. The escape velocity majorly depends on the mass and the radius of the celestial body. There is a difference between orbital velocity and the escape velocity. The orbital velocity is required to reach the planet orbit whereas the escape velocity is required to leave the orbit. The escape velocity formula is given by

V = √[2GM/R]


V is the escape velocity

R is the planet radius

M is the planet mass

R is the gravitational constant
