Neptune and Uranus are only about 15% hydrogen and helium.

Most of their mass comes from heavier gasses, such as methane, ammonia, and water.

As a result, Neptune and Uranus is much more dense than Jupiter.

What gas is in the atmosphere of Uranus and Neptune?

Helium makes up most of Neptunes atmosphere, and some within Uranus. It is this helium that gives Neptune it's blue hue.


Which or the following planets is similar to Uranus in terms of its size and mass?

Neptune is the planet most similar to Uranus in terms of size and mass. Both are classified as ice giants, with Uranus having a diameter of about 50,724 kilometers and Neptune measuring approximately 49,244 kilometers. Their masses are also comparable, with Uranus being about 14.5 times the mass of Earth and Neptune being around 17 times Earth's mass. This similarity in size and composition is why they are often studied together in planetary science.
