The major moons of Uranus are airless bodies. For instance, Titania was shown to possess no atmosphere at a pressure larger than 10–20 nanobar. [42] The path of the Sun in the local sky over the course of a local day during Uranus's and its major moons' summer solstice is quite different from that seen on most other Solar System worlds.
The retrograde moons are grouped into the Carme, Ananke and Pasiphae groups. Saturn has 146 moons with known orbits; 66 of them have received permanent designations, and 63 have been named. Most of them are quite small. Seven moons are large enough to be in hydrostatic equilibrium, including Titan, the second
The moons of the trans-Neptunian objects (other than Charon) have not been included, because they appear to follow the normal situation for TNOs rather than the moons of Saturn and Uranus, and become solid at a larger size (900–1000 km diameter, rather than 400 km as for the moons of Saturn and Uranus).
The planet Uranus and its five biggest moons may not be the sterile worlds scientists have long thought.
Astronomers have discovered a new moon orbiting Uranus — the first spotted in nearly 20 years — and two new moons around Neptune.
Three-decade old data may have just led scientists to make a new discovery about Uranus.
Umbriel, along with another Uranian satellite, Ariel, was discovered by William Lassell on October 24, 1851. [10] [11] [12] Although William Herschel, the discoverer of Titania and Oberon, claimed at the end of the 18th century that he had observed four additional moons of Uranus, [13] his observations were not confirmed and those four objects are now thought to be spurious.
A new study from NASA recently announced that four of Uranus’s five biggest moons may have liquid water oceans beneath their surface. The 4 Major Moons of Uranus May Have Underground Oceans ...
