They are made mostly of hydrogen and helium.
The inner planets (Mercury, Venus, Earth and Mars) are rocky. It is the outer planets (Jupiter, Saturn, Uranus and Neptune) that are gas planets.
They are the outer planets, they are the biggest and they are also called the gas giants because they are all very gassy.
The gassy planets are much more massive than the inner planets, which means that have stronger more far-reaching gravitational fields. That in turn makes them more likely to capture odd collections of rock in the solar system.
Because of the Sun. Yes that's right. The heat from the Sun would make the gas giants unstable over a long period of time.
Mercury is a rock planet; it is solid. Any planet to the left of the asteroid belt (Mercury, Venus, Earth and Mars) are rock planets, or terrestrial planets, while any planet to the right of the asteroid belt are gaseous (Jupiter, Saturn, Neptune, Uranus).
well genuis, there are the "rocky planets" and the "gassy planets"
rocky
They are made mostly of hydrogen and helium.
Uranus and Neptune are bluish gas planets.
gassy planets are made of gas that is stuck together by gravity. Also the answer is in the question.
Jupiter and Saturn are the two gassy planets with lots of moons.
yes the rings are full of gassy rocks which orbit around the planet
No because the inner planets are made of rocky and hard substances and the outer planets are made of gassy lighter substances.
The inner planets (Mercury, Venus, Earth and Mars) are rocky. It is the outer planets (Jupiter, Saturn, Uranus and Neptune) that are gas planets.
No, they have no solid surface to land on and would just get sucked into the center of the planet due to the immense gravity.
No, it is not gassy.
Uranus and Neptune both have thick, gassy atmospheres that were formed by the left-overs of the formation of the planets.
