Planets - Calculate Escape Velocity

Calculator for the escape velocity of objects like rockets from Earth, Moon, Sun and planets, in km/h, m/s, mph and compared to each other. The escape velocity or second cosmic velocity is the speed an object needs at least to escape the gravity of a celestial body, to fly away from it without falling down or getting into an orbit. It is calculated as √2 * circular velocity.

Example: a space ship, which is orbiting Earth and then accelerates above 11.2 kilometers per second, will leave Earth in a hyperbolic trajectory.
