... Space Shuttle to reach a low Earth orbit. How long an orbit takes depends on how high above the Earth the orbit is. For low Earth orbit (about 200 miles above the Earth) it takes about 90 minutes to complete a full orbit. Some orbits are further away and that means it takes them a longer time to orbit around the Earth. There is one special orbit where it takes a full day to orbit around ...

... family of displaced, highly non-Keplerian planetary orbits suitable for the task. The stability proper- ties of this family of orbits and the effect of orbit perturbations are investigated with a sub-group of passively stable orbits identified. Requirements for mirrors utilizing these passively stable orbits are also assessed and ...
