Tilted Rings of Small Planets express
Around distant icy bodies the size of a city, circling beyond Neptune, rings of dust and ice have been found. Small moons often whirl nearby. Mathematical analysis shows that a moon's gravity rocks the ring like a swing, making it tilt. Instead of lying flat in the body's equatorial plane (like at Saturn), the ring can stand at an angle.
This tilt betrays the presence of unseen moons: even if the satellite is too dim, its gravitational 'signature' can be read in the distorted rings. Future sky surveys using photometry (brightness measurements) and spectroscopy (light composition analysis) will test the calculations and may reveal dozens of such ringed planets.

Recent observations have confirmed the existence of rings around minor bodies in the outer Solar System. These objects may possess satellites as well. Here we analytically investigate the interaction between such rings and satellites. We show that the perturbations from the moons may efficiently lead to off-equatorial rings around minor bodies like trans-neptunian objects or centaurs. In particular, we derive criteria for the orbital elements under which such misaligned rings may exist. These considerations will be easily testable with the upcoming deep sky surveys.
Rings around small bodies are sometimes so thin that they can only be noticed by how they momentarily block the light of a distant star.
