Is there water or ice on Neptune?

Neptune is composed mainly of gases, such as hydrogen, helium, and methane. It is believed to have a small rocky core, but the outer layers consist of icy materials like water, ammonia, and methane. However, the extreme pressures and temperatures on Neptune would prevent water from existing in liquid form.

Neptune is a gas giant. It is also sad to have ice, a term scientists use in terms of water, methane, and ammonia which usually occur as solids in the outer solar system. It is not exactly ice as we know it.

yes because, it's the second farthest from the sun and it has vivid colors the landscape
