It is about four times further away from the Earth than the Moon ever gets and orbits the Sun at the same rate as the Earth. It is a … WebThe Earth moves at 30 km/s so from an orbit the same as Earth's you would need a 6 km/s impulse. But it takes 11 km/s to escape the Earth's gravitational pull from LEO, so you really need only sqrt (11 2 + 6 2 ) speed from LEO. That's 12.7 km/s, and since you're already going 7.8 km/s in LEO, you need a 4.9 km/s impulse.
