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. T hey are made of ice, dust and rock."(土星被比其他任 何行星大些的环所包围。
二、 阅读理解A There are eight planets (行星) in our solar system. Here is what you need to know about them.Mercury (水星) is the smallest planet in our solar system. It is the closest planet to the Sun. It is hot during the day. It is freezing cold at night.Venus (金星) is ...
Why are the inner planets solid, and the outer planets made of gas? What is the difference between terrestrial and Jovian planets? How is metallic hydrogen created on Jupiter? How did the asteroid belt between Mars and Jupiter form?
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 ...
Largely composed of gases like hydrogen and helium, the gas planets are thought to have solid or semi-solid cores, possibly of rock, although they're relatively small compared to the planet itself. The gas planets exist in the outer solar system because this region is cooler which allows the...
In the solar system, there are eight planets that orbit the sun. Earth is the third planet from the sun. It is 150 million kilometres away from the sun. Earth is between Venus and Mars. The first four planets are small and rocky. The next four are big and mainly made of gas.When ...

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...
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. ...
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?
