Why is it impossible for a lunar eclipse to happen? Why does the phenomenon of a lunar eclipse occur

Annular lunar eclipse! A lunar eclipse occurs when the Earth is between the Sun and the Moon, and the three spheres are essentially in straight line. Lunar eclipses are divided into umbral and penumbral eclipses, which are further divided into total and partial eclipses.

The difference between a total lunar eclipse and a partial lunar eclipse is not determined by the location of observation, but by whether the Moon enters the Earth's umbra in its entirety. During a total lunar eclipse, the entire Moon is within the Earth's umbra and thus loses direct sunlight from the Sun. During a partial lunar eclipse, the Moon is only partially within the Earth's umbra and thus partially loses its light.

Before and after a total eclipse, there is a one-month partial eclipse phase. Sometimes, because the center of the moon is too far away from the axis of the earth, the entire process of the lunar eclipse is a partial lunar eclipse process. The phenomenon of the moon entering the penumbra of the earth is called a penumbral eclipse, at this time the moon can still be seen on the earth, but the brightness is different, and in the custom, the penumbral eclipse is not considered a lunar eclipse.

If you look at the Sun from the Moon at this time, you can see a partial solar eclipse. The length of the Earth's umbra is about twice the average distance between the Moon and the Earth, and the diameter of the Moon is much smaller than the diameter of the Earth, so there can be no annular lunar eclipse. <>

The moon shines by reflecting the sun's rays. A lunar eclipse occurs when the Earth orbits between the Moon and the Sun, and the Earth blocks the Sun's light shining on the Moon.

Lunar eclipses occur less frequently, but since each eclipse is visible to people halfway around the world, there is a better chance of seeing a lunar eclipse. Lunar eclipses occur on average 1 2 times a year.

When the Moon moves to the shadow part of the Earth, the area between the Moon and the Earth will be obscured by the Earth's rays, and a piece of the Moon will be missing. The Sun, Earth, and Moon at this time happen to be (or almost) in the same straight line.

Lunar eclipses occur up to 3 times in a year, and sometimes none at all.

Hope it helps.

The moon itself doesn't glow and it's completely black when it enters the Earth's shadow.

What is the difference between a solar and lunar eclipse? What are the three celestial bodies involved in a solar and lunar eclipse? Which is the most common, solar or lunar eclipse? So, have you ever seen a lunar or solar eclipse? What's the difference between the two? Let's take a closer look at these two impressive celestial phenomena.

Because when the three planets of the sun, the earth, and the moon are in a straight line, the sun's light is partially blocked by the earth, or all of them, and there will be a lunar eclipse that we often see.

"On the tenth day of the lunar calendar.

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 and produce a total lunar eclipse. If only part of the Moon enters the Earth's umbra, a partial lunar eclipse occurs.

When the Moon enters the penumbra of the Earth, it should be a penumbral eclipse, but because its brightness is weakened very little and it is not easy to detect, it is not called a lunar eclipse, so the lunar eclipse is only a total lunar eclipse and a partial lunar eclipse.

There are only two types of lunar eclipses: total lunar eclipses and partial lunar eclipses.

Causes of lunar eclipses: When the Moon orbits to the shadow of the Earth, the area between the Moon and the Earth will be obscured by the Earth's rays, and a piece of the Moon will be missing. The Sun, Earth, and Moon at this time happen to be (or almost) in the same straight line.

This astronomical phenomenon is called a lunar eclipse.

A lunar eclipse is a natural phenomenon in which when the Sun, Earth, and Moon are exactly or almost in the same straight line (the Earth is between the Sun and the Moon), the light from the Sun to the Moon will be partially or completely obscured by the Earth, resulting in a lunar eclipse. During a lunar eclipse, the direction of the Sun and the Moon is 180° different from each other for the Earth, so the lunar eclipse must have occurred around the 15th day of the lunar calendar. It is important to note that since the orbits of the Sun and Moon in the sky (called the ecliptic and white paths, respectively) are not in the same plane, but are about 5° angles, only if the Sun and Moon are near the two intersections of the ecliptic and the white path, respectively, will have a chance to form a straight line and produce a lunar eclipse.

There are three types of lunar eclipses: partial lunar eclipses, total lunar eclipses, and penumbral lunar eclipses. A partial lunar eclipse occurs when the Moon enters only part of the Earth's umbra; And when the entire Moon enters the Earth's umbra, a total lunar eclipse occurs. As for the penumbral lunar eclipse, it means that the moon only passes over the penumbra of the earth, causing a very slight decrease in the brightness of the lunar surface, which is difficult to see with the naked eye, so it is not noticed.

When a lunar eclipse occurs, if the observer in the shadow of the Earth does not see the Moon at all, a total lunar eclipse has occurred.
