Is it because the earth is too far away from the sun that the four seasons of the earth and the phases of the moon change? If you have any questions, please give me your advice 1. The volume of the sun is 1300000 times that of the earth. Can I think that: If the sun is at zero distance from the earth (if it doesn't vaporize the earth), will there be no day and night change, no four seasons change, and no moon full or clear? Because the sun can shine on almost every corner of the earth and the moon all the year round, that is, all the surface of the earth and the moon is in the extreme day all the year round Now, the reason why the four seasons change is that the sun is so far away from the earth that it almost turns into a parallel light and has no angle Is that right? 2. There is another problem Suppose that there is only one sun and one earth in the vast universe, then we adjust the distance between them from zero to infinity, will there be such a change: the earth is full bright at first, and then the dark part gradually increases until it is completely dark? Is this assumption correct?

First, if the earth is close enough to the sun, there should be no day and night, because even refraction is enough to make the earth bright. Of course, there will be no four seasons. There will be tens of thousands of high temperatures on the surface of the earth. How can there be four seasons? As for the moon's roundness, I feel that under such strong light, if people can really survive, meat

When the earth, the moon and the sun are in the same line, the tide is at its maximum. What is the phase of the moon?
Please draw a schematic diagram of the position of the sun, the earth and the moon, see how many possibilities there are, then analyze the phase of the moon and write it out!
Come on!!
If it's good, there will be extra points!!
But don't answer!!

At this time, the moon phase is called Shuo, that is, the moon can not be seen all day
At this time, the projections of the sun, the earth and the moon are on the same straight line
Sun Moon earth

What is the relationship between the sun, the moon and the earth

The earth revolves around the sun, the moon revolves around the earth, but the sun revolves around the center of the galaxy ~! In the solar system, the huge sun is unique, all the planets, including the earth, their total mass is less than one thousandth of the mass of the sun ~ therefore, it has a huge gravity, the earth and other lines
