A team of astronomers led by the Center for Astrophysics | Harvard & Smithsonian has discovered a rare object far beyond Neptune, from a class known as trans-Neptunian objects, that is moving in rhythm with the giant planet. This object, called 2020 VN40, is the first confirmed body that orbits the sun once for every ten orbits Neptune completes.

This discovery helps scientists understand how objects in the outer solar system behave and how they got there. It supports the idea that many distant objects are temporarily "caught" in Neptune's gravity as they drift through space.
