Jupiter, Saturn, Uranus, and Neptune, which are often called "the gas giants".
Jupiter, Saturn, Uranus, and Neptune.
well its your mom and dad
An inner planet is mostly made of iron and has more mass than outer planets, outer planets are mostly made of gasses, makeing them have less mass. The inner planets are the planets between the asteroid belt and the sun
The "terrestrial planets" are Mercury, Venus, Earth, Mars.
Due to the Sun's strong gravity, the lighter gases would mostly stay in the Sun. The same happens - to a great extent - in the case of the larger planets.
The four outer planets (Jupiter, Saturn, Uranus, Neptune) are all gas giants composed mostly of hydrogen and helium. They are larger and less dense than the inner planets, with no solid surface. Additionally, they all have ring systems and multiple moons.
The outer planets are mostly composed of gasses and ice. The inner planets are mostly composed of iron and rocks. Hope you are a Twilight fan because those ooks are really good. Happy Science! now please enjoy the following ads!:
no 2nd Answer: While some of our large planets are made of gasses, Earth's moon, 'Luna', is mostly rocky.
Hydrogen, and helium. These are currently the most common elements in the Universe.
Well, if you take all the planets together, taking into account that Jupiter and Saturn are enormous and consist mostly of hydrogen and helium gasses, then you'd have to say that the planets are made mostly of hydrogen and helium gas. But if you are allowed to give separate answers for the different planets, you'd say that the four terrestrial planets are made mostly out of silicate (rocky) material with a core of nickel-iron alloy, that Jupiter and Saturn are made mostly of a mixture of hydrogen and helium gasses, and that Urnaus and Neptune are made mostly of hydrogen and helium gases with substantial cores of water ice.
Jupiter, Saturn, Uranus, and Neptune are often referred to as gas giants. They are composed mostly of hydrogen and helium, with no solid surface. These planets are also much larger in size compared to the terrestrial planets like Earth and Mars.
the gasses travel faster than the light. but why. the gasses are not rockyb
