Atmosphere of Uranus - Wikipedia
The atmosphere of Uranus is composed primarily of hydrogen and helium. At depth, it is significantly enriched in volatiles (dubbed "ices") such as water, ammonia, and methane.

2018年2月28日 · The seventh planet in the solar system — and the largest of the ice giants — Uranus has an atmosphere more comparable with Neptune than with Saturn and Jupiter. Known as ice giants, the two...
Uranus - Wikipedia
Uranus has the third-largest diameter and fourth-largest mass among the Solar System's planets. Based on current models, inside its volatile mantle layer is a rocky core, and surrounding it is a thick hydrogen and helium atmosphere.
Uranus - Canadian Space Agency
The atmosphere surrounding the interior of the planet is mostly hydrogen and helium. Despite having the second fastest winds in the solar system (after Neptune), Uranus's atmosphere looks quite calm. Very few clouds are observed in its light blue atmosphere.
The Atmosphere of Uranus - Oxford Research Encyclopedias
As a cold, hydrogen-dominated, intermediate-sized, slowly rotating, and chemically enriched world, Uranus could be the closest and best example of atmospheric processes on a class of worlds that may dominate the census of planets beyond our own solar system.
Uranus/Neptune - University of Oregon
The atmosphere of Uranus is composed of 83% hydrogen, 15% helium, 2% methane and small amounts of acetylene and other hydrocarbons. Methane in the upper atmosphere absorbs red light, giving Uranus its blue-green color.
