This is incorrect.

The speed required for an object to go into space and orbit the Earth (orbital velocity) is about 28,000 km/hr (17,500 mph) at low earth orbit.

It's not impossible to have two objects in LEO traveling in opposite directions. Not sure what you think, but 56,000km/hr is fast enough to do unstoppable damage if they were to collide.
