With what speed should a stone be thrown from the surface of a cosmic body in order for it to fly off an infinitely large distance (in the absence of other cosmic bodies in the vicinity)?

This speed is called the second cosmic speed. It is found from the ratio determined by the equality of the kinetic and potential energies of the body in the gravitational field of the cosmic body. The second space velocity for the Moon is 2.4 km / s, the Earth is 11.2 km / s, Jupiter is 61 km / s, the Sun is 620 km / s, and the white dwarf is 5200 km / s.
