Gas Giants have mostly Hydrogen gas which is the lightest element, so in fact gas giants are in overall density the lightest of all the planets. Jupiter is 318 times the mass of the whole Earth, and roughly 99% of that mass is Hydrogen.
At their cores they may be very dense because of great pressure, but it is still mostly Hydrogen and not as dense as a rocky planet. Gas Giant densities may be very different from each other because along with the Hydrogen they may have more Helium or a larger core of ice and/or rock.
Neptune's overall density is 1.638 g/cm³ - 30% as dense as Earth
Jupiter's overall density is 1.326 g/cm³ - 24% as dense as Earth
Uranus's overall density is 1.27 g/cm³ - 23% as dense as Earth
Saturn's overall density is 0.687 g/cm³ - 12% as dense as Earth
Earth's overall density is 5.515 g/cm3
What else can I help you with?
What sort of surfaces do the inner planets have?
The inner, or terrestrial planets are more dense than the outer planets/gas giants/jovian planets. Through a process of differentiation we find inner planets to typically consist of a molten iron core and a less dense silicate crust.
What do the outer planets have that the inner planets do not have?
outer planets are gas giants whille inner planets are just rocky planets. that includes that outer planets have significant amount of mass than the inner planets
How are the inner and outer planets different?
There are a lot of differences between the inner and outer planets. First of all, they inner planets are also known as the "Rocky planets". THey are rocky, hence their name "Rocky planets". And the outer planets are also known as "Gas Giants." THey are mainly composed of gas, hence their name, "Gas Giants." Another difference is their mass. The outer planets have greater mass than the inner planets. In other words, they are heavier.The inner planets follow orbital paths which, like those of the outer planets,are centered on the sun. But the inner planets, without exception, are nearerto the sun than any of the outer planets are.
Why are the outer planets less dense?
They are made of less dense materials. While the inner planets are made primarily of rock, the outer planets are made mostly of hydrogen and helium.
Are the inner planets smaller than the outer planets?
Yes, the inner planets (Mercury, Venus, Earth, and Mars) are smaller than the outer planets (Jupiter, Saturn, Uranus, and Neptune). The outer planets are known as gas giants and are much larger in size compared to the inner terrestrial planets.

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.
Is this true or false that the inner plants are gas giants and the outer planets are rocky?
False. The outer planets are gas giants (although they have a solid core). The inner planets are 'rocky'.
What criteria are the planets placed into either the inner or outer groups?
Gas giants (for the outer planets), versus rocky planets.
Are outer planets denser than smaller planets?
No. The outer planets are gas planets, which are much less dense than the inner terrestrial planets.
Are the outer planets less dense?
They are made of less dense materials. While the inner planets are made primarily of rock, the outer planets are made mostly of hydrogen and helium.

How do the sizes of the inner planets compare to the sizes of the gas giant planets?
inner planets are small and outer planets are big and cold and gas giants.
