Escape velocity (km/s) 11.186

Formula: v = √(2GM ÷ r)

Step-by-Step Breakdown

1. Values used:

2. Body mass = 5.972e+24

3. Radius = 6,371,000

5. Escape velocity = 11,185.73

6. Escape velocity = 11.186km/s

Did this calculator solve your problem today?

The math behind it

v = √(2GM ÷ r), G = 6.674 × 10⁻¹¹.

Earth → ~11,186 m/s (11.2 km/s).

Independent of mass?

Yes — the escaping object's mass cancels out.
