Kinetic energy = 1/2 x mass x velocity squared.. A satellite drops out of orbit when slower than 17,000 mph. Probably slows to 10,000 mph before impact. 10,000 squared is a big number. If this hits us, it should make a crater about 50m to 100m wide based on the size of meteor crater.
By comparison, meteor crater in AZ is a mile wide and the meteor is predicted to be 50 meters in diameter.
If the crater from this satellite is any bigger, its not a satellite.
