      This is because the moon and sun have different orbits, compared to Earth (where we are viewing the sun or moon from). The moon orbits around the Earth, which takes about a month for each orbit, so sometimes we can see the moon during the day. (The Earth rotates on its own axis too, so it depends on when everything ‘lines up’). Then, the Earth orbits around the sun, but because of the rotation on the Earth’s on axis, for half of each day we are facing away from the sun and can’t see it (during night time).

      I found this hard to describe, compared to how I picture it in my head, so I’m sorry if that doesn’t make sense! I bet there are some cool Youtube videos that show the Earth, sun and moon orbits 🙂

      Everything about space is, in my opinion, difficult to understand! I think Alexandra did a pretty good job of explaining.
      If you want a quick video showing why what you see in a book isn’t really the whole picture, and to illustrate why space objects are really confusing, have a look at this short video that attempts to show you how objects in our solar system rotate around each other whilst traveling through space.

      Pretty crazy!

      Great question, everything about space blows my mind. I think the explanation by Alexandra is great, and found the video Alex uploaded really interesting. I have learnt something from your question 🙂
