The meaning of an eclipse in the constellation _ What does an eclipse mean?

The solar eclipse can be divided into five kinds of solar eclipse images, which are?

In our folk, the phenomenon of solar eclipse is called Tiangou food. In fact, the scientific principle of solar eclipse is that the moon moves between the sun and the earth. If the three are in a straight line, the moon will block the light from the sun to the earth, and the shadow behind the moon will just fall on the earth. At this time, the solar eclipse occurred. Then, the constellation knowledge will help you to answer it. Eclipses can be divided into five types.

When the total solar eclipse occurs, according to the position relationship between the moon and the sun, it can be divided into five kinds of solar eclipse images: 1, initial loss. The moon moves faster than the apparent speed of the sun. The moon caught up with the sun during the eclipse. When the eastern edge of the moon just "touches" the western edge of the sun, it is called the first loss, which is the first "circumscribed" and the beginning of the solar eclipse.

2. Eat well. About an hour after the initial loss, the moment when the eastern edge of the moon and the eastern edge of the sun "cut in" is called a lunar eclipse, which is the beginning of a total solar eclipse (or annular eclipse). For a total solar eclipse, the moon covers the whole sun at this time, and for an annular eclipse, the sun begins to form a ring. During the eclipse, the positional relationship between the shadow of the moon and the first inscribed circle of the sun also refers to the moment when this positional relationship occurs.

The eclipse occurred after the initial loss. Since the first solar eclipse, the moon has continued to move eastward, the part of the sun's circular surface covered by the moon has gradually increased, and the intensity and heat of sunlight have obviously decreased. When the eastern edge of the moon surface is inscribed with the eastern edge of the sun surface, it is called eclipse. The direction of the sky is opposite to that of the map.

3, eat very fragrant. It is the deepest eclipse moment of the sun, and the center of the moon moves to the nearest distance from the center of the sun; In the process of partial solar eclipse, when the sun is covered by the moon the most, the positional relationship between them; In the process of total solar eclipse and annular solar eclipse, when the sun is completely covered by the moon and the distance between the two centers is the closest, the positional relationship between them. It also refers to the moment when the above positional relationship occurs.

4, raw light. The moment when the western edge of the moon and the western edge of the sun "cut in" is called light, which is the end of the total solar eclipse; It usually takes only two or three minutes from eating to lighting, and the longest time is no more than seven and a half minutes.

For an eclipse, after the eclipse, the appearance of the moon continues to move eastward for the sun.

5. Last contact. About an hour after the birth of light, when the western edge of the moon "touches" the eastern edge of the sun, it is called the last contact. Since then, the moon has completely "left" the sun, and the eclipse is over.

Total solar eclipse and annular solar eclipse have the above five processes, while partial solar eclipse has only three processes: initial loss, extreme eclipse and last contact, without food and light.

Another explanation: during the solar eclipse, the positional relationship between the shadow of the moon and the second tangent plane of the sun also refers to the moment when this positional relationship occurs. The last contact was the end of the eclipse.
