* The length of time it takes an object to complete one orbit around Earth. This depends on the object's orbital distance. For example:
* The Moon takes about 27.3 days to orbit Earth.
* The International Space Station orbits Earth in about 90 minutes.
* The physical distance of an orbit. This also depends on the specific orbit. For example:
* The Moon's orbit is about 384,400 kilometers in radius.
* The International Space Station orbits at an altitude of about 400 kilometers above Earth.
Please provide more context so I can give you a specific answer.
