Why are there eclipses? Why are there solar and lunar eclipses

In a word, it is caused by the revolution of the earth around the sun and the revolution of the moon around the earth. When they move to a particular position, they cause solar and lunar eclipses.

The Earth, the Moon, and the Sun are rotating while still revolving, the Moon revolves around the Earth, the Earth revolves around the Sun, and a solar and lunar eclipse occurs when the Earth, the Moon, and the Sun turn to the same straight line.

Solar eclipse: The moon turns between the Earth and the Sun.

Lunar eclipse: The Earth turns between the Moon and the Sun.

When the Sun, Moon, and Earth are in a straight line, the Moon is a lunar eclipse if it is in the shadow of the Earth; If the Moon is in front of the Earth, it obscures the Sun, which is a solar eclipse.

Raw !! on the first floor

It's the first time I've heard of an annular lunar eclipse!!

An eclipse is a natural phenomenon in which the sun, the earth, and the moon happen to be or almost in the same straight line (the moon is between the sun and the earth), and the light from the sun to the earth will be partially or completely blocked by the moon, resulting in a solar eclipse. It should be noted that since the orbits of the Sun and the Moon in the sky are not in the same plane, but at an angle of about 5°, only if the Sun and the Moon are near the two intersections of the ecliptic and the white path, respectively, will have a chance to join in a straight line and produce a solar eclipse. The Moon blocks out the sun's rays, creating shadows on Earth and making some or all of the sunlight unacceptable to certain areas.

The extent to which an observer sees the sun is obscured depends on where they are relative to the moon's shadow. If an observer is in the penumbra (see diagram), they will see a partial solar eclipse, while those in the umbra will see a total solar eclipse.

Both solar and lunar eclipses are formed due to the linear propagation of light.

A solar eclipse occurs when the Moon orbits between the Sun and the Earth. At this time, for parts of the Earth, the Moon is in front of the Sun, and some or all of the light from the Sun is blocked, so it appears as if part or all of the Sun is gone. A lunar eclipse is when the Moon moves to the shadow part of the Earth, and the area between the Moon and the Earth will be blocked by the Earth's sunlight, and a piece of the Moon will be missing.

A lunar eclipse is a total lunar eclipse and a partial lunar eclipse when the earth blocks the sun's rays in the same straight line, causing the moon to become black in the clear night sky.

A solar eclipse occurs when the Moon turns halfway between the Earth and the Sun, and the three celestial bodies are in a straight line or near a straight line, and the Moon blocks the sun's rays.

In addition, a lunar eclipse occurs when the Moon turns to the side of the Earth facing away from the Sun, and the three celestial bodies are in a straight line or near a straight line, and the Earth blocks the sun's rays.

Both solar and lunar eclipses are formed due to the linear propagation of light. So-called"food"It refers to the astronomical spectacle in which a celestial body is completely or partially obscured by another celestial body or its dark shadow. When the Earth is in the middle of the Sun and the Moon, and the Sun's rays hitting the Moon are partially or completely blocked, there will be a lunar eclipse; When the Moon is directly between the Earth and the Sun, and the Sun's rays hitting the Earth are partially or completely blocked, there is a solar eclipse.

Solar eclipse. A solar eclipse, also known as a solar eclipse. In folklore, this phenomenon is called the Tengu Eclipse 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.

Lunar eclipse. A lunar eclipse, also known as a lunar eclipse. in the lunar calendar.

Ten. 5. 16. The Moon moves in the opposite direction to the Sun. At this time, if the center of the Earth and the Moon are roughly in the same straight line, the Moon will enter the Earth's umbra, resulting in a total lunar eclipse. Lunar eclipses occur at least twice a year around the world.

When the Moon travels between the Earth and the Sun, the sunlight is obscured by the Moon, and a solar eclipse occurs. Similarly, when the Earth is between the Sun and the Moon, a lunar eclipse occurs.

However, even if a solar eclipse occurs, it will not be visible from all parts of the Earth, only in the shadow area of the Moon's trembling. For this reason, during a solar eclipse, the observer may be in the penumbra range, and part of the sun is obscured, which is called a partial solar eclipse; Within the umbra, the Sun is completely obscured by the Moon, which is called a total solar eclipse; In the pseudoumbra range, the Moon cannot completely obscure the Sun, leaving behind a ring of light called an annular solar eclipse.
