Eli5| Is orbit distance optional?

211 viewsOtherPhysics

Let me explain, I know the speed something orbit the planet is like 1,800 miles per hour, but is that like for a specific distance??? Could you go faster but at a lower orbit? Or Vice versa Slower at a much higher (or at this point further) orbit?

Yeah exactly, the further away from a planet you are the slower you can move and stay in orbit – for example, the international space station orbits close to earth at 4.8 miles per second, while the moon (much much further away) orbits at only ~0.64 miles per second.

It also has a further distance to go, which adds up to why it takes the moon a month to complete a single orbit while the ISS does roughly every 90 minutes.
