A large cannon, installed in the Moscow region, shoots at an angle of 45 ° to the horizon so that the projectile flies out of the atmosphere and becomes a satellite of the Earth. Will the shell hit the cannon again? Do not take into account the influence of the atmosphere.

Will not get there. The trajectory of the projectile crosses the surface of the Earth at the location of the gun. This means that, moving in its orbit, the projectile can hit the gun only from under the surface of the Earth, i.e., it will fall on the surface of the Earth in another place.
