Is it possible to have a 'figure 8' orbit around the Earth and the Moon? I'm looking for a non-decaying orbit that will not require significant rocket fuel to maintain, unlike the orbits used in the Apollo missions which (I think, not 100% sure) would decay if it was maintained for more that one orbit.
I'm looking for an orbit that can be used for lunar cyclers, so that one lobe of the figure-8 is around the Earth, and the other lobe is around the moon.
For such an orbit, what are the criteria required? What are the different apogees and perigees? What velocities will be involved at different points in the orbit? Where will such an orbit be specifically spaced?
- Is it possible to have an orbit around the earth and moon - This question covers only the very basics and is (unnecessarily in terms of my question) broad.
- synchronized orbit between Earth and the Moon - This question is specific to a stationary orbit; I'm not specifically looking for one of those.
In addition to my above question(s), is it possible for such an orbit to be always facing sunlight, similar to a heliosynchronous dawn/dusk orbit?
