Escape Velocity

Subway station "Rathaus", U 4, Hamburg, Germany.

 

Escape velocity "is the minimum speed needed for a free, non-propelled object to escape from the gravitational influence of a massive body, that is, to achieve an infinite distance from it. Escape velocity is a function of the mass of the object and distance to the center of mass of the object. (...).

The escape velocity from Earth's surface is about 11,186 m/s ( 40,270 km/h; 25,020 mph;)."
