Why does the earth have life while the otherplanets(行星) don't? For one thing, the earth has justthe right temperature. As the third planet from thesun,the earth seems to be just the right distanceaway. The planets which are closer to the sun are sohot because their surfaces are ...
In particular, the C/O ratio is proposed to be a key determinant of the composition of solids that condense from disk gas and are incorporated into planets. Also, planets may leave chemical signatures on the photospheres of their host stars by sequestering heavy elements, or by being accreted...
So could it be that Earth really is unique? All living things on Earth are made of the same building blocks, long carbon-based molecules.所以地球真的是独一无二的吗？地球上所有的生物都有着相同的组成成分，即长碳基分子。Scientists now think that a large proportion of these molecules came fro...

This suggests that our Solar System isn't a typical planetary system, but a relatively rare one. When we look at planets around other stars, we see that planets of a similar mass to Jupiter are found in Earth's spot.这表明，我们的太阳系不是一个典型的行星系，而是一个相对罕见的行星系。
Each of the planets in our solar system has characteristics that set it apart from the others. Some are notable for their size, others for their temperature. Answer and Explanation:1 The planet Jupiter is known for a few different things, the most obvious of which is its sheer size. Jupite...
