WebThe object's distance from the planet's center is also important. The escape velocity from the Earth is about 11.3 kilometers (7 miles) per second. Orbital velocity is the speed needed to stay in orbit. At an altitude of 242 kilometers (150 miles), this is about 17,000 miles per hour. This is just a little less than full escape velocity.
