Why are there solar eclipses Why do solar eclipses occur

It's because the sun is obscured, just kidding. In fact, because the Sun, the Earth and other planets are connected in a line, and the other planets block the sun's rays in the middle, so that the sun's rays cannot reach the Earth, so a solar eclipse occurs, and the other planets are mainly Mercury, Venus, and the Moon (thank you. ）

A solar eclipse is when the moon moves between the sun and the earth, and if the three are exactly in a straight line, the moon will block the sun's light from the earth, and the black shadow behind the moon will fall on the earth, and a solar eclipse will occur.

In folklore, this phenomenon is called the Tengu Eclipse Day (also known as the Tengu Swallowing Day). Solar eclipses only occur at the New Year, when the Moon and the Sun are conjunct. Solar eclipses are divided into partial solar eclipses, total solar eclipses, annular solar eclipses, and total annular eclipses.

You can't look directly at the sun when observing a solar eclipse, otherwise it will cause temporary blindness, and in severe cases, permanent blindness.

A solar eclipse is actually a physical phenomenon in which light travels in a straight line in the same homogeneous medium. When the sun, the earth, and the moon are basically in a straight line, and the moon is located between the sun and the earth, when the shadow of the moon falls on the earth, the moon covers the sun's rays, and the sun cannot be seen in the area within the shadow, this phenomenon is called "solar eclipse".

For a solar eclipse to occur, the Moon needs to be between the Sun and the Earth, and the three would have to be almost in a straight line. Only then will the shadow of the Moon be cast on Earth, allowing observers on Earth to see the phenomenon of the eclipse. However, the ecliptic and white planes are not coplanar, and there is an angle between them.

In addition, due to the gravitational perturbation of other celestial bodies, the yellow-white angle is not a fixed value, the minimum is, the maximum is, and the average is.

A solar eclipse is when the moon circles the earth and turns between the sun and the earth, if the sun, the moon, and the earth are exactly lined up or close to a straight line, the moon blocks the sunlight that shoots to the earth, and the black shadow behind the moon falls on the earth, and the solar eclipse phenomenon occurs. People in the shadow of the moon on the earth began to see the sun gradually weakening, the sun surface was obscured by a round black shadow, when the sky turned dark, all the brightest stars and planets could be seen in the sky, and after a few minutes, the sun gradually appeared from the edge of the moon's black shadow, and began to produce light and recircle.

Solar and lunar eclipses are typical examples of light propagating in a straight line in celestial bodies. It is not every time a solar eclipse occurs when the moon moves between the sun and the earth, and two conditions need to be met for a solar eclipse to occur. First, solar eclipses always occur on New Year's Day (the first day of the lunar calendar).

Eclipses are not guaranteed on all new suns, because the Moon's orbit (the white path) and the Sun's orbit (the ecliptic) are not in the same plane. The plane of the white and the plane of the ecliptic have an angle of 5°9. A solar eclipse can occur if both the Sun and the Moon move near the intersection of the white and ecliptic at the New Moon, and the Sun is at a certain angle from the intersection (eclipse limit), which is the second condition to be met.

Since the orbits of the Moon and the Earth are not perfectly circular, and the distance between the Sun and the Moon and the Earth is sometimes near and far, the shadow formed by the sun's rays being obscured by the Moon can be divided into umbra, pseudoumbra (formed when the Moon is far away from the Earth) and penumbra on the Earth. The observer is in the umbra range and can see a total solar eclipse; An annular solar eclipse can be seen in the pseudoumbra range; In the penumbra range, only a partial solar eclipse can be seen.

Because the moon obscures the sun's rays, a long shadow area is formed on the backlit side of the moon. When the Moon orbits between the Earth and the Sun (which must occur on the first day of the lunar calendar), and the three planets are exactly or nearly in a straight line, the Moon blocks our view of the Sun, and a solar eclipse occurs. Generally speaking, the most common scenario is that there are four solar and lunar eclipses in a year

Two solar eclipses and two lunar eclipses.
