That the ε ring does have such a fine structure has been confirmed by many occultation observations. [18] The ε ring seems to consist of a number of narrow and optically dense ringlets, some of which may have incomplete arcs. [18] The ε ring is known to have interior and exterior shepherd moons—Cordelia and Ophelia, respectively. [27]
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]
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]
James Ludlow Elliot (June 17, 1943 – March 3, 2011) was an American astronomer and scientist who, as part of a team, discovered the rings around the planet Uranus. [2] [3] Elliot was also part of a team that observed global warming on Triton, the largest moon of Neptune. [4] [5]
Uranus is one of those worlds, and while its rings are so faint they weren't even spotted until the late 1970s, scientists have shown a great deal of interest in them.Now, a new observation ...
Uranus is the third-largest and fourth most massive planet in the Solar System. It orbits the Sun at a distance of about 2.8 billion kilometers (1.7 billion miles) and completes one orbit every 84 years. The length of a day on Uranus as measured by Voyager 2 is 17 hours and 14 minutes. Uranus is distinguished by the fact that it is tipped on ...
