What is the phenomenon of "stars turning into barrels"?

"The stars move" means that the position of the constellation is constantly changing every year. In spring, Virgo appears in the east and Taurus sinks to the west. In summer, Scorpio rises at a low altitude in the southeast and Leo sinks to the west. In autumn, Aquarius appears in the east and Scorpio sinks to the west. In winter, Taurus rises and Aquarius sinks again. In fact, the earth revolves around the sun along its own elliptical orbit, which leads to the phenomenon that stars turn around. Astronomers have measured thousands of stars with precision instruments and found many similar facts, which prove that this is a phenomenon caused by the revolution of the earth. When the earth moves in orbit, its position is constantly changing. The revolution of the earth is very regular, with a period of one year.
