Uranus is the seventh planet from the Sun, and it's the third largest planet in our solar system – about four times wider than Earth. Uranus is a very cold and windy planet. It is surrounded by faint rings, and more than two dozen small moons as it rotates at a nearly 90-degree angle from the plane of its orbit.
Uranus' atmosphere is mostly hydrogen and helium, with a small amount of methane and traces of water and ammonia. The methane gives Uranus its signature blue color. While Voyager 2 saw only a few discrete clouds, a Great Dark Spot, and a small dark spot during its flyby in 1986 – more recent observations reveal that Uranus exhibits dynamic ...
At ultraviolet and visible wavelengths, Uranus's atmosphere is bland in comparison to the other giant planets, even to Neptune, which it otherwise closely resembles. [23] When Voyager 2 flew by Uranus in 1986, it observed a total of 10 cloud features across the entire planet.
The upper atmosphere of Uranus is the source of the far ultraviolet (90–140 nm) emissions known as dayglow or electroglow, which, like the H 3 + IR radiation, emanates exclusively from the sunlit part of the planet.
18 sty 2017 · Uranus owes its vibrant blue-green hues not from unusual oceans but from an upper atmosphere flush with methane, which absorbs the sun's red light and scatters blue light back to our eyes.
8 lis 2024 · Uranus is an ice giant (instead of a gas giant). It is mostly made of flowing icy materials above a solid core. Uranus has a thick atmosphere made of methane, hydrogen, and helium. Uranus is the only planet that spins on its side. Uranus spins the opposite direction as Earth and most other planets. Time on Uranus
