Why are the inner planets solid, and the outer planets made of gas? Why do gas planets form first? Why do all gas planets have rings? Why do gas planets have rocky moons? Why are gas planets bigger than terrestrial planets? Why do gas planets have large atmospheres?
根据第六段第一行“Jupiter is the largest planet in our solar system. It is made of gas.”(木星是我们的太阳系中最大的行星。它由气体组成。)可知B项错误。C项,土星周围的光环由三种东西组成。根据第七段第一行“Saturn is surrounded by bigger rings than any other planet. They are made of ice...
At present only one of these planets has been found to transit the face of its parent star. Its radius is that of a slightly inflated gas giant. Models of the structure and evolution of these planets are beginning to show how clues to their evolutionary history may be encoded in their ...
High-resolution simulations reveal that when circumstellar disks in young star clusters collide, their gravitational forces create “tidal bridges” of gas, which collapse into PMOs. This explains why so many of these free-floating objects exist and why they often come in pairs. ...

Instead, they are made up of thick atmospheres. 4. Size and Structure: The outer planets are much larger than the inner planets. Their massive size contributes to their ability to hold onto large amounts of gas, which is why they are referred to as "giants." 5. Conclusion: Because they...
Mars is one of the fourterrestrial planets. Mercury, Venus, and Earth are the other three. All of the terrestrial planets are made up of rock and metals. The remaining planets are classified as the outer gas giants. What are Mars moons called?
