 There are several thousand satellites that are still orbiting the Earth that are dead. When a satellite dies, it doesn't just fall out of the sky. It's still got orbital velocity, just like the moon. It doesn't need an engine to stay up, right? And so there's plenty of dead satellites up there. And when you launch a satellite, the way you get it into orbit is with a rocket. And the upper stage of the rocket that pushes the satellite to orbital velocity has got orbital velocity too. And so it ends up in orbit. And so there's several thousand leftover rocket stages.
