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. The outer planets are further away, larger and made up mostly of gas. The inner planets (in order o...
比如说,太阳系里的行星(planets in our solar system),它们是怎么形成的,它们的大小、质量、温度(size, mass, & temperature),等等 尽管有很多知识都忘了,但是我觉得它们非常有趣。 Oh yeah, definitely. I remember that when I was a primary school student, I read a lot aboutstars and galaxiesfrom so...
No one expects there could be life on any of the other planets in our solar system. 没人相信在太阳系内的其他星球上存在生命。 Jupiter, Saturn, Uranus, and Neptune are made up of gases. All of these planets are also ve...
Someday, in 62 the outer planets of our solar system, humankind will want to do 63 send small probes that merely fly rapidly by them. In time, we will want 64 spacecraft that will go 65 orbit around these alien planets, land robots on their moons, and even return rock and soil sampl...
Discover the outer planets of our solar system. Learn the outer planet definition, the difference between inner and outer planets, and outer planet...
This volume gives an integrated summary of the science related to the four giant planets in our solar system. It is the result of an ISSI workshop on 芦A comparative study of the outer planets before the exploration of Saturn by Cassini-Huygens禄 which was held at ISSI in Bern on January...
8.In our Solar System, some of it was captured by the outer planets before it was lost. 9.They are the first cirrus clouds seen on an outer planet. 它们是首次在外行星上发现的卷云. 10.The planet is twice as large as the earth and is the smallest exoplanet ever found. ...

Yeah, I remember back in the science class during my primary school years, we were introduced to the nine planets in the solar system: Mercury –the smallest one among the nine, Venus, Earth of course, Mars, and there’s Jupiter, Saturn, Uranus, Neptune, and what’s the last one? Oh...
In our Solar System, which consists of eight planets total, there are four inner and four outer planets, with the asteroid belt between them. The inner, or Earth-like planets, include Mercury, Venus, Earth and Mars, and are not to be confused with inferior planets, which are those closer...
