Escape Velocity Calculator

Find the speed to escape a body's gravity.

Escape velocity 11,185.73
Escape velocity (km/s) 11.186

Formula: v = √(2GM ÷ r)

Step-by-step with your numbers:
1. Values used:
2. Body mass = 5.972e+24

4.
5. Escape velocity = 11,185.73
6. Escape velocity = 11.186km/s
Did we solve your problem today?

Escape velocity is the minimum speed to break free of gravity without further thrust.

The math behind it

v = √(2GM ÷ r), G = 6.674 × 10⁻¹¹.

Worked example

Earth → ~11,186 m/s (11.2 km/s).

FAQ

Independent of mass?

Yes — the escaping object's mass cancels out.
