The outer planets, also known as gas giants (Jupiter, Saturn) and ice giants (Uranus, Neptune), have low densities primarily because they are composed mostly of light gases like hydrogen and helium, along with ices and other volatile compounds. Unlike the terrestrial planets, they lack solid surfaces due to their thick atmospheres, which transition gradually into their liquid or gaseous interiors. This composition and structure result in their lower overall density compared to the rocky inner planets.

Could you land on the outer planets?

No. The outer planets do not have solid surfaces. Those planets are made of gases held together by gravity.


What are the inner planets and the outer planets and how do the planets in the two groups differ?

The inner planets are Mercury, Venus, Earth and Mars. The outer planets (they are separated by the asteroid belt) are Jupiter, Saturn, Uranus, and Neptune. The outer planets are different than the inner planets because the outer planets are not solid. They are all made up of gas. However, the inner planets are rocky and hard.


The first four outer planets do not have solid?

All the outer planets probably have solid cores. However, they do not havewhat we call a solid surface.Incidentally, there are only four outer planets altogether.There are only 4 "outer planets". They do not have a solid surface.


What makes the inner planets different from the outer planets?

The inner planets are small and rocky, the outer planets are much larger and have no solid surface, they are called the gas giants.


What characteristics set the inner planets apart from the outer planet and name the outer planets?

The inner planets are all rocky planets, whereas the outer planets are gas giants. Pluto is the exception. The outer planets also make 99% of our planets and are outside the asteroid belt.


What do inner planets have that outer planets dont have?

the inner planets are hot and or warm. the outer planets have rings. they both have the asteriod belt in the middle. they both have4 planets. the inner planets are smaller, made of rock and are AWESOME!


Which is not true in the inner planets?

The inner planets are closer to the Sun compared to the outer planets, have solid rocky surfaces, and are smaller in size compared to the outer planets.


What 3 ways do inner planets differ from outer planets?

Inner planets are smaller and made of rock and metal, while outer planets are larger and predominantly made of gas and ice. Inner planets have few or no moons, while outer planets have numerous moons. Inner planets have solid surfaces, while outer planets do not have solid surfaces, instead having thick atmospheres.


Why are the inner planets solid while the outer planets are gaseous?

Bill Gates hired moon shovelers to transport all the solid matter to closer planets.


What is the difference between terrestial planets and outer planets?

terrestrial are planets that are the inner planets since there are made up of rock. but on the other hand. the outer planets are the gas giants. or the outer planets. they are made up of various gasses.


What outer planet has a solid core?

I guess that would be Mars, which has an orbit outside the Earth's orbit. The first four planets have solid cores, while the four outer planets are gas giants.


What is the outer planets not a gas giant?

Pluto is not a planet so you cant really say that all of the outer planets are made of gasses the inner planets are made of solid materials
