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 ...
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 sizes and masses of many of the moons of Jupiter and Saturn are fairly well ... There has not yet been an orbiter around Uranus or Neptune for long-term study of ...
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 ...
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.
Confirmed as Uranus XXI, it was named after the drunken jester Trinculo in William Shakespeare's play The Tempest. Trinculo is the second smallest of Uranus' 28 moons after Ferdinand and is approximately only 18 km wide. Animation of Trinculo's orbit around Uranus.
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 ...
