Escape Velocity Calculator – Calculate Escape Velocity

Earth's escape velocity is 11.2 km/s (25,020 mph or 40,270 km/h). This is the speed a rocket needs at Earth's surface to escape Earth's gravity without further propulsion.

No. A feather and a rocket need the same escape velocity from the same planet. The planet's mass matters, not the escaping object's mass. Gravity pulls harder on heavier objects, but they also need more energy to accelerate - these effects cancel out.

With continuous propulsion, yes. Escape velocity is the speed needed for a ballistic (unpowered) trajectory. Rockets don't reach 11.2 km/s instantly - they accelerate continuously, burning fuel as they climb.

You'll either fall back down or go into orbit. Below escape velocity but above orbital velocity, you follow an elliptical path that eventually returns you to the starting point (unless you hit the planet first).

Gas giants like Jupiter are much more massive than Earth. Jupiter is 318 times Earth's mass. Even though it's also larger (which reduces escape velocity), the mass effect dominates. Jupiter's escape velocity is 60 km/s - over 5 times Earth's.
