Elements on Neptune's surface

Answer 1

Elements found on Neptune include:

Molecular hydrogen (H2) - 80.0%

Helium (He) - 19.0%

Methane (CH4) - 1.5%

Hydrogen Deuteride (HD) - 192ppm

Ethane (C2H6) - 1.5ppm

Ammonia ice

Water ice

Ammonia hydrosulfide

Answer 2

Neptune's surface is predominantly composed of icy materials such as water, methane, and ammonia. These elements form various compounds that give Neptune its bluish color. Additionally, there may be traces of carbon-based molecules and other organic compounds, although the exact composition is still being studied.

Answer 3

It is much like Uranus and the other giant planets, with a thick atmosphere of hydrogen, helium, methane, and ammonia, a relatively low density, and a rapid period of rotation.

Answer 4

Neptune is a gas planet, meaning it has no real surface. It does have a small rocky core in the middle. The surface of the planet is often riddled by extremely strong storms.
