are uranus and neptune gas giants?

A gas giant is a large planet composed mostly of gases, such as hydrogen and helium, with a relatively small rocky core. The gas giants of our solar system are Jupiter, Saturn, Uranus and Neptune.

Saturn: Saturn is the second largest of the gas giants; with a mean diameter of 120,536 km, it is just slightly smaller than Jupiter. However, it is significantly less massive than its Jovian cousin, with a mass of 569 x 1024 kg (or 569,000,000,000 trillion metric tons).

Let's take a look at how big Neptune is, and compare it to some other objects that you might be familiar with. Neptune is the 4th largest planet in the Solar System, after Jupiter, Saturn, and Uranus. It's much larger than the terrestrial planets: Mercury, Venus, Earth and Mars. The diameter of Neptune is 49,500 km.

Uranus is made of water, methane, and ammonia fluids above a small rocky center. Its atmosphere is made of hydrogen and helium like Jupiter and Saturn, but it also has methane. The methane makes Uranus blue. Uranus also has faint rings.

Unlike terrestrial planets whose composition is rocky, gas giants have a mostly gaseous composition, such as hydrogen and helium. They do have some rocky material, although this is most often found in the planet core. The four gas giants are (in order of distance from the Sun): Jupiter, Saturn, Uranus, and Neptune.

They are sometimes called gas giants because they are large and made mostly of gases. Small amounts of rocky materials are only found deep in the cores of Jovian planets. In the solar system, Jovian planets are located farther from the sun than terrestrial planets, and are therefore cooler.

Even if that weren't the case, the answer to your question would be no. There is no mechanism in the current Solar System which could cause the orbit of Neptune to move inside of that of Uranus....

The four gas giants in our solar system are Neptune, Uranus, Saturn, and Jupiter.

Gas giants are sometimes known as failed stars because they contain the same basic elements as a star. Jupiter and Saturn are the gas giants of the Solar System.

Uranus is slightly larger in diameter than its neighbor Neptune, yet smaller in mass.

Both Earth and Uranus have atmospheres. However, Earth's atmosphere is made up of oxygen, nitrogen and other gases, while Uranus' atmosphere is largely made up of hydrogen, helium and methane ice.

After Mars, there is an asteroid belt that separates the inner planets from the outer ones. The outer planets are called the jovian planets, meaning huge gas giant. These planets in order are Jupiter, Saturn, Uranus, and Neptune. ... Size is the most obvious difference between the inner and outer planets.

In short, since Saturn is colder than Jupiter at any particular altitude, its cloud layers occur deeper within it's atmosphere. Uranus and Neptune, due to their even lower temperatures, are able to hold condensed methane in their very cold tropospheres, whereas Jupiter and Saturn cannot.

Physical characteristics The planet is often dubbed an ice giant, since at least 80% of its mass is a fluid mix of water, methane and ammonia ice. Unlike the other planets of the solar system, Uranus is tilted so far that it essentially orbits the sun on its side, with the axis of its spin nearly pointing at the star.

The first is the fact that Uranus has no solid surface. It's mostly composed of ices: methane, water and ammonia. And then it's enshrouded by an atmosphere of hydrogen and helium. ... There's no process inside Uranus, like volcanism on Earth, that would give life inside the planet a form of energy.

Jupiter and Saturn are mostly comprised of Hydrogen and Helium, while Neptune and Uranus are mostly comprised of Methane. Even thought they are all called Gas Giants, Neptune and Uranus are much smaller than Jupiter and Saturn. (2) Jupiter's Great Red Spot The GRS rotates completely in six days.

The outer planets are called the jovian planets, meaning huge gas giant. These planets in order are Jupiter, Saturn, Uranus, and Neptune. Pluto comes after Neptune, but it is no longer considered a planet. It is now a dwarf planet. The outer planets are also called the gas giants because of their composition.
