The stars are moving very fast, but they are also very far away.To compare it on an earthly scale: Imagine a Formula 1 race car, which runs 350 km/h. That’s pretty fast. Imagine that the car is in a certain direction, that you close your eyes and open them again a minute later. Could the car still be found in the same direction? And if I tell you that this car is driving in Mexico City (and you are in the Netherlands)?
Something similar applies to the stars.Barnards Star (the star that shifts most to the sky, but is too light to see with the naked eye) is no less than 140 km/s (relative to the sun). This means that in 1 year he is 4,418,064,000 km away. However, he also stands almost 6 light years away from us, or about 56,406,054,240,000 kilometers. If we compare it again to that race car in Mexico City: In that one year the star moves as much to the sky as the race car does when he moves 720 metres. (and then I do not even count that those 140 km/s in reality is for the most part to us, and not 芒 鈧?虄opzij芒 鈧劉).
There are other answers given and here is a supplement.Everything you see is connected to each other.
All the stars you can see with the naked eye come from our galaxy (= Star system).With the naked eye we can see one other galaxy-Andromeda-but not his stars, I come back later.
Stars do not stand arbitrarily in the sky and do not move randomly through space, they are connected by gravity.Our Milky Way galaxy consists of a spiral, everything revolves around a center. Our relative position in relation to the other stars remains fairly similar. So it is no arbitrariness.
Galaxies are also tied back together through gravity in clusters and superclusters.Distances are also very large. Andre Engels already describes it and then takes a relatively close-up star.The Andromeda system is 2.5 million light years away from us and, incidentally, moves in a job that our kruist芒 鈧?娄 about about four billion years. So movement is not arbitrary and smaller because there is a connection between our movement and that of the stars.
Then finally.They are not at the same place in the sky. In The course of 1 night, even the Arctic star is not exactly on the same square… but they seem to be in the same place in relation to each other.
Everything is relatively:-)
Trust your senses.If they haven’t been in the same spot for years but thousands of years what we know from Astrolab, sextant sightings and historical star maps then you can safely assume that those speeds are conceived to make a theoretical mathematical model throbbing.
The redshift that is known to the Doppler effect of light can simply be the color of a star.Sun and Moon also have their own frequency spectrum.
