Gaseous planets have very large masses and so a strong gravitational field.
The terrestrial planets in order from the thickest to thinnest atmospheres Venus, Earth, Mars, and Mercury. Since the gas giants are almost entirely made of gas, it is difficult to determine where the atmospheres end.
Because the inner planets are made of rock but the outer planets are made of gas(except for Pluto).
Gasses and ice . (:
All the inner planets are rocky or terrestrial planets.
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.
A planet could not be made of fire, but there are probably planets in the universe that are entirely covered in lava. These would usually be very young planets.
Neptune is one of several planets made up almost entirely of ice, so technically, yes it is.
No. Saturn is one of the "gas giant" planets, which means it is made up entirely of gases, some of which condense due to the planet's tremendous gravity.
Life probably does not exist on any of the known planets (except earth). But if life does exist on one of those planets, it would probably be on Mars. Venus is way too hot, Mercury does not have an atmosphere, and the other four planets are made up almost entirely of gas.

there are 9 planets
the inner planets made up of rocks while the outer planets are made up of gases and liquids.
All the planets are made of "matter" and that has "mass".
Because the inner planets are made of rock but the outer planets are made of gas(except for Pluto).
these planets are small rock solid planets.
I think the question is probably about "light elements".The inner planets are relatively warm and small. This means they have notbeen able to keep the lightest elements, hydrogen and helium, as gases.
Type your answer here... all planets are made of gasses
