What is Earth's escape velocity?

Earth's escape velocity is approximately 11,186 m/s (about 40,270 km/h or 25,020 mph).

Does escape velocity depend on the object's mass?

No. Escape velocity depends only on the planet's mass and radius, not on the mass of the escaping object.

Escape Velocity Calculator

Formula

v_{e} sc a p e = s q r t (2 GM / r), w h er e G = 6.674 \times 1 0^{- 11} N \cdot m^{2} / k g^{2}, M i s ma ss, an d r i sr a d i u s .

Determine the escape velocity for any planet or celestial body. Earth's escape velocity is about 11.2 km/s; this tool lets you compute it for any mass and radius combination.

Common use cases:

Space mission planning
Comparing planetary gravity
Astrophysics education
