What is the phenomenon that stars move in a line?

The phenomenon that the stars move in a row is called the star Sunday motion, which is caused by the rotation of the earth and the movement of the stars relative to the earth. So the rows of stars are actually an optical illusion caused by the rotation of the earth.

1. The concept of Sunday sports:

Also known as Sunday apparent motion, it describes the obvious apparent motion state of celestial bodies observed by observers on earth every day, especially in the near polar region. This is because the earth rotates around the axis, which makes all celestial bodies move around this axis (from the observer's eyes, it is around the North Star).

This circle is called Sunday circle, and it takes 23 hours, 56 minutes and 4.09 seconds to complete a circle (that is, a whole sidereal day). Sunrise and sunset of the sun and the moon are also the embodiment of Sunday sports.

2.？ The concept of the earth's rotation:

Refers to the movement of the earth rotating around its own axis. The rotation of the earth is one of the basic movements of the earth, which makes day and night appear alternately and leads to the change of sunshine and time on the earth.

The rotation axis of the earth refers to an imaginary line passing through the north and south poles of the earth. The time required for the earth to rotate once is called the earth rotation cycle, also known as the Earth Day or the day and night cycle. The rotation period of the earth is about 24 hours, which is what we usually call a day.

The reasons for the relocation are as follows

1. Planet or satellite:

A long string of stars in the night sky may consist of multiple planets or satellites. These celestial bodies move along their respective orbits under the action of the earth's gravity, resulting in the phenomenon of star movement.

2. Apparent motion of stars;

Due to the rotation and revolution of the earth, the position of stars in the night sky will change, which is called the apparent motion of stars. This kind of movement causes the position of the stars in the sky to change, forming a long string of stars.

3. Meteor shower:

When comets or asteroids enter the earth's atmosphere, the heat generated by high-speed motion and air friction will make them burn and form a meteor shower. These meteors look like a long string of stars moving in the night sky.

4. artificial satellite:

A long string of stars in the night sky may also be made up of artificial satellites. These satellites orbit the earth, leaving light trails in their orbits, forming the effect of a long string of stars.

5. Optical illusion:

Sometimes, we may see a long string of stars moving, but in fact this is just our visual illusion. This illusion may be caused by eye adaptability, atmospheric refraction or other optical phenomena.
