Nobody knows because all we can see and measure is the top of its atmosphere. It might have a rocky core but that is speculation.
The gas giants - and this includes Uranus - DON'T have a surface you might walk on.
Uranus is a gas planet because it is one of the outer planets.
crappy
Uranus is a "gas giant" planet; we're not entirely certain that it HAS a "surface".
Uranus has a gas surface
No. The planet has no surface like the terrresterial planets do.
Uranus doesn't really have a surface. It is a huge ball of ice, liquid and gasses. No one has been able to land on the surface of Uranus because it is not solid enough to support weight.
Uranus's surface is made of frozen gases
The surface conditions of Uranus are not well understood, as it lacks a solid surface like Earth. It is mainly composed of gases such as hydrogen and helium, with an icy and rocky core. The upper atmosphere of Uranus is made up of clouds of ammonia, water, and methane.
Saturn's surface has not been proven to be smooth. One of Saturn's moons have been confirmed to be smooth and mirror like though.
The surface of Uranus is predominantly composed of gas, with no solid surface to stand on like Earth. It is covered by thick layers of clouds made up of gases such as ammonia, methane, and water vapor. These clouds give Uranus its blue-green color and create a somewhat hazy appearance.
Do you pay attention in school?
