Neptune, for example, has an atmosphere made of hydrogen and helium (with just a tinge of methane), and it doesn’t really have a surface—or, at least, not what we think of as a surface.

A study suggests the ice giants Uranus and Neptune aren't quite as watery as previously thought. They may also contain huge amounts of frozen methane, potentially solving the puzzle of how they ...

Scientists have uncovered the secret ingredient fueling supercharged storms on Uranus and Neptune: methane. Uranus and Neptune are the outermost planets of the solar system and are known as ice ...

Atmosphere: Neptune's "surface" can therefore be said to be composed of about 80% hydrogen and 19% helium, with a trace amount of methane. The surface layer is also permeated by roving bands of ...
