Gas giants are large planets that contain more than 10 times the mass of Earth, they are also known as the Jovian or Outer Planets. Their compositions are mostly gases, such as hydrogen, and small amounts of rocky material (mostly at their cores).

The order of the planets from closest to the Sun outwards is; Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and finally Neptune. The largest planet in the solar system is Jupiter, followed by Saturn, Uranus, Neptune, Earth, Venus, Mars with the smallest being Mercury.

2024年6月25日 · Explore 47 fascinating facts about planets in our solar system and beyond. From Mercury to Neptune, uncover the wonders of the universe.

2023年8月7日 · The outer planets of our solar system consist of Jupiter, Saturn, Uranus and Neptune; all four are gas giants made up primarily of hydrogen and helium, with thick gaseous outer layers and liquid interiors.

The outer planets are mostly made of gases like hydrogen, helium, methane, and ammonia. These worlds are massive and they have rings around them. One of the interesting facts about the outer planet is, that you can not stand on its surface as these are made of gases.

2014年4月23日 · In our Solar System, astronomers often divide the planets into two groups — the inner planets and the outer planets. The inner planets are closer to the Sun and are smaller and rockier....
