These rings display a previously unnoticed wavy pattern, suggesting that they're being pulled at by two tiny moons.
"These patterns may be wakes from small moonlets orbiting exterior to these rings," the researchers write in their paper on the pre-print site arXiv.org.
So why didn't Voyager 2 see these moons as it zipped past?
The researchers suggest these moons are so tiny, and also so dark, that they would have blended into the background for the spacecraft. Being "dark" means they barely reflect any light, as is the case with most of the moons in the area, and also Uranus's dark rings.
The icy extraterrestrial body, which was supposed to have become dislodged from its orbit by now is gradually changing its trajectory and moving towards the sun from within the Oort cloud into the Kuiper belt, something that has never been seen before.
Researchers believe that L91’s trajectory is influenced by another mysterious body lurking in the outer reaches of the solar system, the unknown giant Planet Nine, aka Planet X.
Although L91 orbits our solar system’s sun, it never comes closer than 50 astronomical units, and at its farthest extreme it is a whopping 1,430 AU away. Each AU equals the distance between the Sun and Earth.

Again in connection with the 2 previous threads by mikesingh and Terrapop... should I stop wearing my tinfoil hat? Why is this old Planet X/Niburu thing keeps popping up?

I don't think we have to worry.
