What is Uranus' atmosphere mainly composed of?

Answer 1

Uranus is another member in the family of gas planets of the solar system. First, it has methane mixed in with the hydrogen and helium that make up most of the giant planets. Methane gives Uranus its unusual color. Second, Uranus appears to have a core, or center, of melted rock, which changes into an ocean made up of water, ammonia and other elements. Finally, the ocean changes into the blue-green cover of clouds. Scientists believe that the layers of the planet are not separate, like those of an onion, but gradually blend with one another.

Answer 2

The atmosphere on the planet of Uranus is made up mostly of helium and hydrogen. Uranus is also one of the coldest planets.
Uranus has methane in its atmosphere which is why it is blue and it also has hydrogen and helium. Also ammonia
Really cold and made of 82% hydrogen with 15% helium, and a few other gases.
It has a gassy atmosphere.

Answer 3

2.3% methane, 82.5% hydrogen, 15.2% helium, and a very small amount of other gases.

Answer 4
