Why does dwarf planet Quaoar have a ring? | Popular Science

Scientists have discovered a ring system around a small object beyond the orbit of Neptune, a surprising discovery in itself. But the observation comes with a mystery to boot: How is this ring system possible when, by all accounts, it shouldn't exist?

The ring in question orbits Quaoar, a small dwarf planet that lies more than 6.5 trillion miles from the sun—roughly 44 times the distance between Earth and our star.

Scientists discover ring around dwarf planet but can't explain it | TechSpot

The big picture: Aside from Saturn's iconic rings, several other planets also possess rings. Scientists still don't fully understand their properties or how they form, and a recent discovery seriously challenges what they thought they knew.

Dwarf planet Quaoar (pronounced "Kwawar") lies far out beyond Neptune in a region of orbiting solar system objects known as the Kuiper Belt.
