The atmosphere of Uranus, like those of the larger gas giants, Jupiter and Saturn, is composed primarily of hydrogen and helium. At depth it is significantly enriched in volatiles (dubbed "ices") such as water, ammonia and methane. The opposite is true for the upper atmosphere, which contains very few gases heavier than hydrogen and helium due to its low temperature. Uranus's atmosphere is the coldest of all the planets, with its temperature reaching as low as 49 K.
The Uranian atmosphere can be divided into three main layers: the troposphere, between altitudes of −300[a] and 50 km and pressures from 100 to 0.1 bar; the stratosphere, spanning altitudes between 50 and 4000 km and pressures of between 0.1 and 10−10 bar; and the hot thermosphere (and exosphere) extending from an altitude of 4,000 km to several Uranian radii from the nominal surface at 1 bar pressure.[1] Unlike Earth's, Uranus's atmosphere has no mesosphere.
The troposphere hosts four cloud layers: methane clouds at about 1.2 bar, hydrogen sulfide and ammonia clouds at 3-10 bar, ammonium hydrosulfide clouds at 20-40 bar, and finally water clouds below 50 bar. Only the upper two cloud layers have been observed directly-the deeper clouds remain speculative. Above the clouds lie several tenuous layers of photochemical haze. Discrete bright tropospheric clouds are rare on Uranus, probably due to sluggish convection in the planet's interior. Nevertheless observations of such clouds were used to measure the planet's zonal winds, which are remarkably fast with speeds up to 240 m/s.
Little is known about the Uranian atmosphere as to date only one spacecraft, Voyager 2, which passed by the planet in 1986, has studied it in detail. No other missions to Uranus are currently scheduled.
nasty..kinda sour
Uranus (appropriately named!) and Neptune i believe!
Uranus mainly has a hydrogen and helium atmosphere, which also contains ices. The ices are frozen water, ammonia and methane. Although a lot larger than the earth, the gravity on Uranus is 0.886g, where one g is the earths gravity. This is due to the relatively low density of the planet.
Uranus actually does have clouds but they most likely do not consist of the same molecular constructs as clouds on Earth.
Uranus is the seventh planet from the Sun. It has the coldest atmosphere in the Solar System with methane in the uppermost atmosphere.
Uranus is mainly hydrogen and helium, but also contains a large amount of frozon ammonia and methane. Being a gas planet, it has no surface like earth, the atmosphere just gets thicker as you go futher in.
uranus uranus uranus
It is a gassy planet like Jupiter, Uranus, and Neptune
No, it's a planet.
Uranus
gases
Uranus... interestingly, most of Uranus's atmosphere rotates faster than the interior; the planet's fastest winds blow portions of the atmosphere around the planet in only 14 hours.Uranus.

No it is not breathable, because the planet is full of dangerous gases such as methane.
If you mean what is in its atmosphere, its methane, which is why the planet has a blueish-green tint.
No. There is no oxygen in Neptune's atmosphere
Both Uranus and Neptune have methane in their atmosphere which absorbs red light, allowing the blue hues to be reflected. Neptune is a lot more of a blue colour than Uranus, but Uranus has more methane in its atmosphere. Its though that other constituents in Neptune enrich its blue colour.
