# General effects (and narrative practicality) of a moon with an extreme elliptic orbit

This is more for fluff and illustrative exotica, but I'm keen on an idea where my new world has a moon that orbits elliptically, but has a fast inward close orbit followed by a longer round trip the other way. I just want a moon that rather than being observed waxing and waning, becomes distinctly smaller and then bigger to the point where it is a large presence in the sky.

As I say, it's more an aesthetic than practical notion. But if, in reality, such an orbit would start ripping oceans up and crushing forests, then I'll chuck a nebula into the sky or something... As usual, I've tried and failed to get my head round the "Astrophysics for dummies" blogs and articles that explains this stuff via wikipedia and such.

Any thoughts, views or opinions on whether any major physical impacts as a result of this phenomenon would massively effect a human settlement, would be really helpful.

• "Any thoughts, views or opinions on this" is an unbounded, subjective topic and may result in this being closed as primarily opinion-based or needs more focus. If you're concerned with the natural phenomena that may result from this type of orbit, I would strongly suggest changing your in-body question to indicate this. – Frostfyre Dec 20 '19 at 15:21
• Looks like all big moons in solar system have near-circular orbits. However, I don't know whether this is a law of orbital mechanics or just a tendency. – Alexander Dec 20 '19 at 19:38
• Big moon means big planet it is a moon of. Means big tidal influences. Means tidal circularization works faster. en.wikipedia.org/wiki/Tidal_circularization – puppetsock Dec 20 '19 at 20:29
• You could reasonably simplify this question into "how realistic is this" (with a reality-check flag), and based on the responses to that, think about asking for further ideas. As it stands, this question is too unfocussed. – Starfish Prime Dec 20 '19 at 20:36
