It would do some damage, just break, or depending on where it hit it could REALLY hurt.
The speed at which a satellite re-enters the Earth's atmosphere can vary, but it typically ranges from 17,000 to 25,000 miles per hour (27,000 to 40,000 kilometers per hour). This high speed is necessary to counteract the pull of gravity and maintain a stable orbit around the Earth.
Sputnik was the first satellite to orbit the Earth. It was Russian and transmitted a radio signal. It is possible that a earlier satellite could be in orbit, without any communications this would be the same as a cannon shell etc. So long as an object can reach orbit it will constantly drop towards the planet and because the planet is round the object will rotate around being pulled by gravity
Skylab fell out of orbit in 1979.
If the moon fell out of orbit, it would either crash into Earth or be slingshotted away into space, depending on the angle and speed of its descent. Either scenario would have catastrophic consequences for both the Earth's environment and life forms.
Sputnik was a "family name" for a series of Russian satellites. Sputnik 1 (the very first artificial satellite launched by the Russians) was in orbit in 1957, but only briefly. It was in a very low orbit, and it fell out of orbit and burned on re-entry shortly afterward, which is was designed to do. It had accomplished it's mission.
You would die
it would float
You might get hurt.
it would break
You would die.
you would get hurt then it would bounce off.
It would break. -____-
