Lambda Ring
A narrow and relatively faint planetary ring surrounding Uranus, located approximately 50,024 kilometers from the planet's center.
The Lambda ring, originally designated 1986 U1R, was discovered through observations made by NASA's Voyager 2 spacecraft during its January 1986 encounter with Uranus.
It is situated between the Delta and Epsilon rings and measures approximately 2 kilometers in radial width.
Unlike many of Uranus's dense classical rings, the Lambda ring contains a more diffuse concentration of particles and dust.
Observations have revealed variations in particle density, including localized concentrations or clumps of material distributed along the ring.
A faint additional dust structure has also been identified just inward of the main Lambda ring.
The Lambda ring demonstrates that even extremely narrow planetary rings can possess irregular internal structures and nonuniform distributions of material.
