The outer planets (with the exception of the dwarf planet - Pluto) are called "gas giants" for two reasons - they are GIANT (in size/mass/gravity etc.) compared to Earth and the inner solar system "rocky" or "terrestrial" planets and are composed mainly of a gaseous atmosphere (with, its hypothesized, a small rocky core at the center).
because all of the outer planets or jovian planets are all big and it is made up of gas unlike the inner or terrestrial planets, they are made of rocks.
Because they are large planets that are made of gases.
well they have gas in them
gas giants.
Gas Giants :)
They are called the "outer planets." But also the "gas giants" because they all have thick atmospheres and no accessible surface.
False. The outer planets are gas giants (although they have a solid core). The inner planets are 'rocky'.
The outer planets are Gas Giants, also known as Jovian planets.
The outer planets are also called Jovian planets or gas giants. These planets include Jupiter, Saturn, Uranus, and Neptune. These outer planets are gaseous with no solid surfaces and only liquid cores.
Jovian planets or gas giants
The outer planets are sometimes called Jovian Planets or gas giants or for Uranus and Neptune (Ice Giants)
Gas giants.
They are all gas giants.
Gas giants.
The inner planets are rocky and the outer planets are gas giants.
