The escape velocity is always 2–√2 times the orbital velocity. At the Moon’s distance from Earth its orbital velocity is 1.022 Km/s. The escape velocity at this distance is therefore 1.445 Km/s but this would have to be directed away from Earth.
At the Earth’s distance from the Sun, the escape velocity is over 41 Km/s.
Were the Moon to escape Earth, it would still be trapped in a heliocentric orbit, were it not to achieve this latter velocity.
