The former was named the η ring. The latter were dubbed rings 4, 5 and 6—according to the numbering of the occultation events in one paper. [8] Uranus' ring system was the second to be discovered in the Solar System, after that of Saturn. [9]
Uranus is surrounded by rings and moons in the new Webb image. The central bright feature on the planet is Uranus' seasonal north polar cap. - NASA/ESA/CSA/ STScI
The largest is located twice as far from Uranus as the previously known rings. These new rings are so far from Uranus that they are called the "outer" ring system. Hubble also spotted two small satellites, one of which, Mab, shares its orbit with the outermost newly discovered ring. The new rings bring the total number of Uranian rings to 13. [162]
Satellite rings and gaps in the rings are named for scientists who have studied these features; drawings that show these names are also included in the pertinent Transactions volume. Names for atmospheric features are informal at present; a formal system will be chosen in the future.
Saturn is well known as the planet with rings, but it's hardly the only one. As it turns out, rings around planets aren't all that rare, and at least a few of the planets in our solar system have ...
Illustrations depict how Uranus' magnetosphere, or protective bubble, was behaving before Voyager 2's arrival (left) and during the spacecraft's flyby (right).
The two innermost moons, Cordelia and Ophelia, are shepherds of Uranus's ε ring, whereas the small moon Mab is a source of Uranus's outermost μ ring. [12] There may be two additional small (2–7 km in radius) undiscovered shepherd moons located about 100 km exterior to Uranus's α and β rings. [24]
Gertrude / ˈ ɡ ɜːr t r uː d / is the largest known crater on Uranus's moon Titania. A peak-ring impact basin, it is roughly 326–400 kilometers across, [1] [2] 1/5 to 1/4 of Titania's diameter. [a] Gertrude was first observed by the Voyager 2 spacecraft on its January 1986 flyby of the Uranian system.
