Re: What-If 0058: "Orbital Speed"

Thank you Mikeski! I should have looked up how high a geostationary orbit is (about 6 times the radius of the earth, to my surprise) and thought about it. Wikipedia has a nice to-scale picture of satellite heights on the "Medium Earth orbit" page.

Re: What-If 0058: "Orbital Speed"

I don't understand this. Geostationary satellites orbit at the same speed the earth revolves. So if you launch one of them, why would you need to gain any speed in addition to the speed you already have from being on the surface of the earth?
