Dwarf planet Quaoar has a weirdly big ring of debris encircling it

Dwarf Planet Quaoar has a Ring

The debris in the ring should've formed a moon this far from the planet. Hasn't it heard of the Roche Limit?

Dwarf planet hosts a ring that’s unexpectedly far from the planet

At that distance, the ring should condense into a moon. Why hasn't it?

Planetary rings are observed not only around giant planets1, but also around small bodies such as the Centaur Chariklo2 and the dwarf planet Haumea3. Up to now, all known dense rings were located close enough to their parent bodies, being inside the Roche limit, where tidal forces prevent material with reasonable densities from aggregating into a satellite. Here we report observations of an inhomogeneous ring around the trans-Neptunian body (5000

Scientists shocked to find ‘ring’ that shouldn’t be in our solar system

A ring that scientists had thought couldn’t exist has been found around a planet in our Solar System.

Astronomers astonished by ring around frigid distant world Quaoar

The small distant world called Quaoar, named after a god of creation in Native American mythology, is producing some surprises for astronomers as it orbits beyond Pluto in the frigid outer reaches of our solar system.

Astronomers Discover Ring Around Distant Frigid Planet Near Pluto

The small distant world called Quaoar, named after a god of creation in Native American mythology, is producing some surprises for astronomers as it orbits beyond Pluto in the frigid outer reaches of our solar system. Researchers said on Wednesday they have detected a ring encircling Quaoar akin to the one around the planet Saturn. But the one around Quaoar defies the current understanding of where such rings can form - located much further away…
