Are they as high up that it could start orbiting?

1. No

2. Orbit is more about speed than height. You have to get high enough that the atmosphere doesn't aggressively degrade your velocity, but the key is to hit ~8km/s, although that number changes depending on your altitude.

edit: 30km/s -> 8km/s

30 km/s is ~the speed at which Earth orbits the Sun. For orbiting Earth you just need a mere <8 km/s.

Orbiting has more to do with velocity than altitude.

jvanderbot|1 year ago

Specifically, you need to be moving approx 10 km/s which 22,000 mph or mach 30.

Ahh yes, of course! I guess they are not high enough for geo stationary orbit?
