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.
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.
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'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.
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.
May 2, 2023 · The seventh planet from the sun and the coldest planet in the solar system, Uranus has 27 known moons. These bodies are extraordinary in the solar system because they share the axial tilt of 98...
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.
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 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.
Jun 1, 2024 · Uranus, seventh planet in distance from the Sun and the least massive of the solar system’s four giant, or Jovian, planets. Uranus has more than two dozen moons, five of which (Umbriel, Miranda, Ariel, Titania, and Oberon) are relatively large, and a system of narrow rings.
