How fast do you need to go to leave for good?
Escape velocity is the minimum speed at which an object's kinetic energy exactly equals the gravitational potential energy binding it to a body — go this fast (with no further thrust) and you'll never fall back.
Escape velocity grows with the square root of mass and shrinks with the square root of radius — this is why escaping a neutron star takes a meaningful fraction of light speed, while escaping the Moon takes barely 2.4 km/s.

Escape velocity: 11,185.727 m/s
An object needs to reach 11,186 m/s to escape this body's gravity permanently.
