The James Webb Space Telescope has snapped a glowing new portrait of Uranus that showcases the ice giant’s typically hidden rings, moons, weather and atmosphere — features that were nowhere to ...
What’s known about Uranus could be off the mark. An unusual cosmic occurrence during the Voyager 2 spacecraft’s 1986 flyby might have skewed how scientists characterized the ice giant, new ...
A solar wind event squashed the protective bubble around Uranus just before Voyager 2 flew by the planet in 1986, shifting how astronomers understood the mysterious world.
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).
For two pairwise interacting point particles, the gravitational potential energy is the work that an outside agent must do in order to quasi-statically bring the masses together (which is therefore, exactly opposite the work done by the gravitational field on the masses): = = where is the displacement vector of the mass, is gravitational force acting on it and denotes scalar product.
S/2023 U 1's orbit exhibits nodal precession with an average period of about 5,000 Earth years and apsidal precession with an average period of about 5,100 Earth years. [ 3 ] S/2023 U 1 is part of the Caliban group, a cluster of retrograde irregular moons of Uranus that includes Stephano and the group's namesake Caliban . [ 5 ]
Alone but certainly unique, Uranus rotates at a nearly 90-degree angle and is surrounded by 13 icy rings. Images of which were captured in rich detail last year by the James Webb Space Telescope .
Verona Rupes is the tallest known cliff on Miranda, a moon of Uranus, and plausibly holds the record for the highest cliff in the Solar System.It was discovered by the Voyager 2 space probe in January 1986.
