Sun between Uranus rings

An artist’s conception of the Sun between Uranus’ rings.

Planet Uranus has faint rings. The inner rings are narrow and dark. The outer rings are brightly colored and easier to see.

The Uranian rings are composed of extremely dark particles, which vary in size from micrometers to a fraction of a meter. Thirteen distinct rings are presently known, the brightest being the ε ring. All except two rings of Uranus are extremely narrow – they are usually a few kilometers wide. The rings are probably quite young; the dynamics considerations indicate that they did not form with Uranus. The matter in the rings may once have been part of a moon (or moons) that was shattered by high-speed impacts.
