Uranus's moons are divided into three groups: thirteen inner moons, five major moons, and ten irregular moons. The inner and major moons all have prograde orbits and are cumulatively classified as regular moons. In contrast, the orbits of the irregular moons are distant, highly inclined, and mostly retrograde.
Uranus has 28 known moons, including five major moons: Miranda, Ariel, Umbriel, Titania, and Oberon. The moons are sometimes called the "literary moons" because they are named for Shakespearean characters, along with a couple of the moons being named for characters from the works of Alexander Pope.
The planet Uranus has 27 known moons. Uranus’s five largest moons—Miranda, Ariel, Umbriel, Oberon, and Titania—range from about 240 to 800 km (150 to 500 miles) in radius. All were discovered telescopically from Earth, four of them before the 20th century. Ten small inner moons were found by Voyager 2 in 1985–86. An 11th tiny inner moon ...
Oberon and Titania are the largest Uranian moons, and were the first to be discovered – by William Herschel in 1787. William Lassell, who had been the first to see a moon orbiting Neptune, discovered the next two, Ariel and Umbriel. Nearly a century passed before Gerard Kuiper found Miranda in 1948.
May 2, 2023 · The 5 major and regular moons are in Uranus' equatorial plane and are the only moons of Uranus that are large enough to be spherical. All of the regular moons show impact craters and...
All of Uranus's inner moons (those observed by Voyager 2) appear to be roughly half water ice and half rock. The composition of the moons outside the orbit of Oberon remains unknown, but they are likely captured asteroids.
Jun 1, 2024 · Uranus has 27 known moons that are accompanied by at least 10 narrow rings. Generally, the rings are located closer to the planet than the moons. Some small moons orbit just outside the rings, while the largest moons orbit beyond the small moons, and other small moons orbit much farther out.
Jun 1, 2024 · Uranus’s five largest moons range from about 240 to 800 km (150 to 500 miles) in radius. All were discovered telescopically from Earth, four of them before the 20th century ( see below Observations from Earth ). Ten small inner moons were found by Voyager 2 in 1985–86.
Uranus is a very cold and windy planet. It is surrounded by faint rings, and more than two dozen small moons as it rotates at a nearly 90-degree angle from the plane of its orbit. This unique tilt makes Uranus appear to spin on its side.
Uranus has 27 known moons. While most of the satellites orbiting other planets take their names from Greek or Roman mythology, Uranus' moons are unique in being named for characters from the works of William Shakespeare and Alexander Pope.
