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 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 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 planet Uranus and its five biggest moons may not be the sterile worlds scientists have long thought.
There are 293 confirmed moons in our cosmic neighborhood. By studying these worlds, astronomers hope to learn about ancient asteroid collisions, space volcanoes, and the origins of life itself.
Astronomers have discovered a new moon orbiting Uranus — the first spotted in nearly 20 years — and two new moons around Neptune.
Uranus: 7th Planet: Herschel first reported the discovery of Uranus on 26 April 1781, initially believing it to be a comet. [17]: 11 January 1787 p: 15 February 1787 Titania: Uranus III Uranus I (1787–1797) Herschel. [18] [19] He later reported four more spurious satellites. [20] Oberon: Uranus IV Uranus II (1787–1797) o: 28 August 1789 [21 ...
Three-decade old data may have just led scientists to make a new discovery about Uranus.
