A close-up view of the ε ring of Uranus. The ε ring is the brightest and densest part of the Uranian ring system, and is responsible for about two-thirds of the light reflected by the rings. [12] [21] While it is the most eccentric of the Uranian rings, it has negligible orbital inclination. [23]
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]
The normally faint inner and outer rings of Uranus shine in the latest image, including the planet’s closest yet incredibly dim and diffuse Zeta ring. Nine of Uranus’ 27 known moons can also ...
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 .
Most pictures of Uranus in textbooks show it as a bright blue, featureless ball. But the James Webb Space Telescope, the preeminent new observatory that senses light at invisible, infrared ...
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 ...
With the super-sharp optics system used at the W. M. Keck Observatory, de Pater and Hammel found an 11th ring around Uranus, a narrow sheet of rocky debris. The ring, the innermost of its siblings, is about 3,500 kilometers (2,200 mi) wide and centered about 39,600 kilometers (24,600 mi) from the planet's core.
Three-decade old data may have just led scientists to make a new discovery about Uranus.
