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 ...
This list contains a selection of objects 50 and 99 km in radius (100 km to 199 km in average diameter). The listed objects currently include most objects in the asteroid belt and moons of the giant planets in this size range, but many newly discovered objects in the outer Solar System are missing, such as those included in the following ...
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. The 4 Major Moons of Uranus May Have Underground Oceans ...
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 ...
Size comparison of Earth and Uranus. Uranus's mass is roughly 14.5 times that of Earth, making it the least massive of the giant planets. Its diameter is slightly larger than Neptune's at roughly four times that of Earth. A resulting density of 1.27 g/cm 3 makes Uranus the second least dense planet, after Saturn.
