Here's the real reason why they appear that way:
* stora avstånd: Stars are incredibly far away. The closest star to our Sun is Proxima Centauri, which is over 4 light-years away. That's a mind-boggling distance! Because they are so far, even though they move, their movement is too small and slow for us to notice without very precise instruments.
* Jordens rotation: The Earth spins on its axis, making it seem like the stars are moving across the sky. Denna rotation skapar en illusion av en himmelsk sfär, med stjärnorna som verkar stiga i öster, reser över himlen och ligger i väst.
* Earth's Orbit: In addition to the daily rotation, Earth also orbits the Sun. This yearly journey means the stars appear to shift slightly over time, but this change is very subtle and takes months to become noticeable.
So, while it looks like stars are stuck on the sky, they are actually constantly moving. We just don't see it because of our perspective and the incredible distances involved.
