Although there is no well-defined solid surface within Uranus's interior, the outermost part of Uranus's gaseous envelope that is accessible to remote sensing is called its atmosphere. [18] Remote-sensing capability extends down to roughly 300 km below the 1 bar (100 kPa) level, with a corresponding pressure around 100 bar (10 MPa) and ...
Uranus's castration allowed the Titans to rule and Cronus to assume supreme command of the cosmos. [39] For this "fearful deed", Uranus called his sons "Titans (Strainers) in reproach" and said that "vengeance for it would come afterwards."
In the 1990s, it was determined that Uranus and Neptune were a distinct class of giant planet, separate from the other giant planets, Jupiter and Saturn, which are gas giants predominantly composed of hydrogen and helium. [1] Neptune and Uranus are now referred to as ice giants. Lacking well-defined solid surfaces, they are primarily composed ...
In the outer Solar System, hydrogen and helium are referred to as "gases"; water, methane, and ammonia as "ices"; and silicates and metals as "rocks". In this terminology, since Uranus and Neptune are primarily composed of ices, not gas, they are more commonly called ice giants and distinct from the gas giants.
This is why the later discovered bodies were also named accordingly. Two more bodies that were discovered later, and considered planets when discovered, are still generally considered planets now: Uranus, discovered by William Herschel in 1781; Neptune, discovered by Johann Gottfried Galle in 1846 (based on prediction by Urbain Le Verrier)
Uranus has been the butt of a lot of jokes (stop giggling). And it doesn't help that it's huge — roughly four times the size of Earth — or gassy with an atmosphere comprised partly of methane.
Voyager 2's visit to Uranus may have left us with the complete wrong impression of the ice giant for nearly 40 years, according to a new study. ... Engineering and Medicine called on NASA to make ...
He called the new planet the "Georgian star" (Georgium sidus) after King George III, which also brought him favour; the name did not stick. [45] In France, where reference to the British king was to be avoided if possible, the planet was known as "Herschel" until the name "Uranus" was universally adopted. [46]
