In 1986 the slow period of Uranian moon discoveries would be offset by a burst of discoveries. Making its flyby of the Uranian systemVoyager 2tripled the number of known moons all with diameters of between 16 and 96 miles (26 and 154 kilometers)according to NASA. These moons were Juliet...
They're calling for a mission to Uranus and its moons, as a number of Uranus' moons have displayed telltale signs of having internal liquid oceans and chemical compositions that could be favorable to life. Related: Extreme microbes in salty Arctic water could aid search for life on Mars ...

The individual ring particles were found to be of low reflectivity. At least one ring, the epsilon, was found to be gray in color. The moons Cordelia and Ophelia act as shepherd satellites for the epsilon ring. Uranus Statistics Discovered by William Herschel Date of discovery 1781 Mass (kg...

of a star behind the planet, the American astronomer James L. Elliot discovered the presence of five rings encircling the equator of Uranus. Four more rings were discovered in January 1986 during the exploratory flight of Voyager 22. In addition to its rings, Uranus has 15 satellites ('moons...
The cameras of the Voyager II spacecraft detected six small, previously unseen moons circling Uranus,which doubles to twelve the number of satellites now known as orbitingthe distant planet 选项: A、which doubles to twelve the number of satellites now known as orbitingdoubling to twelve the number...
Earlier in 1610, Galileo had discovered the four so-called “Galilean moons” of Jupiter: Io, Europa, Ganymede and Callisto. Although we now know that Jupiter has several dozen moons of varying shapes, sizes, and orbits, at the time the announcement of just four natural satellites had led ...
Astronomers have discovered two tiny moons orbiting Neptune and one circling Uranus, bringing the number of their known moons to 16 and 28 respectively. Uranus' new moon, the first detected around the ice giant in over two decades and possibly the smallest of its ilk, is just 5 miles (8 ...
Between Cordelia, Ophelia and Miranda are a swarm of eight smallsatellitescrowded together so tightly that astronomers don't yet understand how the little moons have managed to avoid crashing into each other. Anomalies in Uranus' rings lead scientists to suspectthere might still be more moons...
