How does the constellation change in a day?

If the answer is wrong, don't give it. Why do constellations go from east to west in one day?

On a clear moonless night, standing in an open place, you will see the stars twinkling in the dark sky. If you keep looking at the sky, you will find that the stars rise in the east, slowly sweep across the sky, and then set in the west, just like the sun rises and sets every day. In fact, this is also the result of the earth's rotation from west to east. Every day, except that stars can be seen orbiting the earth from east to west, every star rises from the horizon about 4 minutes earlier than the previous day. So at the same time every night of the year, we see different stars, and the position of the constellation is gradually moving westward. For example, the familiar Orion, 65438+ rises in the east at dusk in early February; Three months later, just after dusk, Orion has flashed in the southern sky; But by the end of spring, it was already dusk. With the progress of the season, the slow movement of the constellation to the west is the result of the earth's revolution around the sun. If we can see the stars during the day, then we will see the sun moving eastward between constellations. The sun moves eastward about 1 every day, which is equivalent to twice the diameter of the sun. In this way, it carried out a so-called "annual star-watching movement" on the celestial sphere within one year. Generally speaking, there are two kinds of motion phenomena of stars: one is the Sunday apparent motion caused by the rotation of the earth, which causes the stars to rise and set every night; The other is the annual apparent motion caused by the earth's revolution, which makes constellations appear and disappear with the seasons, and the hidden time also changes. The two should not be confused.
