Are the constellations all the same in shape?
Also, the stars in the same constellation rarely have anything to do with each other, but visually they are very close and the distance from us is very different.
The shape of the constellation is not immutable. Although these stars seem to have been fixed in the same position for the past 3000 years, in fact they have been moving relative to the sun at a speed of up to 10 kilometers per second.
Because they are too far away from us, it is difficult for us to observe the change of their position unless there are 30 thousand years. Because of this action, 50,000 years later, bucket handle of the Big Dipper will bend his hips even more than today. Although the shape of the constellation will change with time, we probably won't change the name of the constellation because of it.
In addition, according to the different seasons and the time when individual constellations reach zenith, the 88 constellations are roughly divided into four groups, namely, spring constellations, summer constellations, autumn constellations and winter constellations.
Why do the starry sky change in spring, summer, autumn and winter? This is because when the earth revolves around the sun, the side facing away from the sun is the starry sky we can see in the season that night. As the earth rotates around the sun, it gradually changes its position, so the starry sky in the background slowly changes.
