What is the escape velocity required for a rocket to leave Earth’s gravity?

The escape velocity required for a rocket or any object to overcome Earth’s gravitational pull and enter space is approximately 11.2 kilometers per second, which equals about 40,270 kilometers per hour. This velocity is the minimum speed needed to break free from Earth’s gravity without additional propulsion. Achieving escape velocity requires powerful rocket engines that generate enough thrust to counter gravity and atmospheric drag. While rockets do not always travel at a constant speed of 11.2 km/s, they reach equivalent total energy through staged propulsion. Escape velocity depends on the planet’s mass and radius and differs for other celestial bodies.
