The major moons of Uranus are thought to have formed in the accretion disc, which existed around Uranus for some time after its formation or resulted from a large impact suffered by Uranus early in its history. [31] [32] This view is supported by their large thermal inertia, a surface property they share with dwarf planets like Pluto and Haumea ...
For the small outer irregular moons of Uranus, such as Sycorax, which were not discovered by the Voyager 2 flyby, even different NASA web pages, such as the National Space Science Data Center [6] and JPL Solar System Dynamics, [5] give somewhat contradictory size and albedo estimates depending on which research paper is being cited.
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. New study on moons of Uranus raises chance of life Skip to main content
Nine of Uranus’ 27 known moons can also be seen as blue dots, including some of the smaller ones that exist within the rings. ... One year on Uranus lasts around 84 Earth years, and for about a ...
A new study from NASA recently announced that four of Uranus’s five biggest moons may have liquid water oceans beneath their surface.
As the below graph demonstrates, the maximum absolute magnitude (total inherent brightness, abbreviated H) of moons we have detected around planets occurs at H = 18 for Jupiter, H = 17 for Saturn, H = 14 for Uranus, and H = 12 for Neptune. Smaller moons may (and most likely do) exist around each of these planets, but are currently undetectable ...
Trojan moons Calypso and Telesto (trojans of Tethys), and Helene and Polydeuces (trojans of Dione). These small moons share their orbits with Tethys and Dione, leading or trailing either. [180] [181] Outer large satellites Rhea, Titan, Hyperion, and Iapetus. [179] Titan is the only satellite in the Solar System to have a substantial atmosphere ...
