“Sweet Moon,” William Shakespeare wrote in “A Midsummer Night’s Dream,” “I thank thee for thy sunny beams; I thank thee, Moon, for shining now so bright.” Centuries later, the moons of Uranus pay homage to the famous playwright. While most satellites orbiting other planets take their names from ancient mythologies, Uranus’ moons are unique in […]
May 2, 2023 · Exploring Uranus' moons can reveal how ocean worlds may form and remain active, defining the extent of the habitable zone in the solar system. As a result, a future mission to explore Uranus and ...
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.
Uranus - Moons, Rings, Atmosphere: 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. They are estimated to be between about 10 and 80 km (6 and 50 miles) in radius, and they ...
Spotting the post-Voyager moons is an impressive feat. They're tiny – as little as 8-10 miles (12-16 km) across, and blacker than asphalt. And of course, they're about 1.8 billion miles (2.9 billion km) away from the Sun. All of Uranus's inner moons (those observed by Voyager 2) appear to be roughly half water ice and half rock.
Moons. Moons. 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. All of Uranus' inner moons appear to be roughly half water ice and half rock.
Uranus is the seventh planet from the Sun, and it's the third largest planet in our solar system – about four times wider than Earth. The diameter at its equator is 31,763 miles (51,120 kilometers). 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 ...
