This seems like a good place to start off the Uranus and Neptune forum: with the next ice-giants mission.
I will admit to not knowing a whole lot about the Neptune Orbiter With Probes (NOWP), other than the fact that it's in the planning stages, and a few other details I've gathered from Wikipedia and various other Internet sources. Anyone care to get this one going with a bit more information? |

Possibly that the node crossings of the two orbits are offset from each other. E.g., imagine if Saturn's A rings were inclined 20 degress and B rings were inclined 160 degress. The A and B rings would be coplanar if the node crossings were the same. (If going by convention of using the ascending node, then node crossings are offset by 180 degrees.) But if the node crossings were offset, you would get the B rings twisted out of the plane of the A rings. The two rings will still come close at two points, but this is because their orbits are circular. With two elliptical orbits, particularly if they do not have resonant periods, objects in the two orbits could potentially never get close to each other.
