What is the difference between a lunar absences and a lunar eclipse, and the difference between a mo

A lunar eclipse is when the Earth blocks the light from the moon, so you can't see part of it.

The absence of the moon means that the sun cannot shine on the far side of the moon, so the other part cannot be seen.

The legendary lack of a moon is actually a type of lunar eclipse, which is called a partial lunar eclipse. It is a lunar eclipse phenomenon that occurs when the Moon is not very fully in the umbra zone of the Earth.

A lunar eclipse is a special astronomical phenomenon that refers to the fact that when the Moon moves to the shadow part of the Earth, the area between the Moon and the Earth will be blocked by the Earth's rays, and a piece of the Moon will be missing.

I think that a lunar eclipse is a type of lunar absence, and there are many possibilities for lunar absence.

<>1. The moon phase is the name in astronomy for the part of the moon seen on the earth illuminated by the sun. As the moon moves a large distance from west to east in the starry sky every day, its shape is constantly changing, which is called the moon phase.

2. A lunar eclipse is a special astronomical phenomenon, which means that when the moon moves to the shadow part of the earth, the area between the moon and the earth will be blocked by the earth because the sunlight is blocked, 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 can be divided into three types: partial lunar eclipses, total lunar eclipses, and penumbral lunar eclipses.

Lunar eclipses can only occur around the 15th day of the lunar calendar.

The main difference between a lunar eclipse and a moon phase is that the edges of the Earth's shadow are blurred in the lunar eclipse, while the moon phase is very clear.

The reason why the earth's shadows are blurred is because the edges of the shadows are like this. Standing in the sunlight, you look at your own shadow and you will also see that the edges of the head are blurred. And because the Moon has no atmosphere, the boundary between light and dark in the phases of the moon, that is, the morning and dusk lines on the moon, is extremely distinct.

In addition, the shape of the moon phase does not change noticeably overnight, while the shape of a lunar eclipse changes very quickly, and the difference can be seen in a few moments. Even if you have the same lunar eclipse, you will see different shadows when you stand in different geographical locations. For example, in eastern China, the moon has already sunk in the west at the beginning of the lunar eclipse, but for Europe, the moon has just risen at the same time.

Analysis: The phases of the moon are changes in the size of the bright parts of the moon seen due to the different positions of the observers.

A lunar eclipse is a phenomenon in which the bright parts that would otherwise be visible are obscured due to the obscuration of the Earth's shadow. These are two completely different astronomical phenomena.

a) Let's talk about the phases of the moon first:

1.When the Moon is exactly between the Sun and the Earth (the first day of the lunar month), the part facing the Earth happens to be the dark side of the Moon, and the observer on the Earth cannot see the bright part of the Moon in any case, which is the New Moon. This darkness is what it "should" be.

2.When the moon turns to the extension of the earth and the sun (the fifteenth day of the lunar month), the earth is facing the entire bright side of the moon, and the observer on the earth can see the entire bright disk-like moon, which is the full moon.

3.Upper and lower quarter moons: When the angle between the Earth, the Sun and the Moon is 90 degrees, the hemisphere of the Moon facing the Sun is still bright, but only half of it is facing the Earth, and observers on Earth can only see the half-light and half-dark phases of the moon.

This is the Quarter Moon. Others such as waning moon, gibbous moon, etc. are similar.

2) Lunar eclipse: When the moon is full, the earth is exactly between the moon and the sun, and at this time, the shadow of the earth may fall right on the moon, so that the moon, which should be bright, loses its light, which is a lunar eclipse.

It's okay now.,If you don't understand.,You can add my qq*** I'm teaching geography.,That's what I'm doing this day.。

The moon is seen by the name of the sun-illuminated part.

Different names mean different things and that's it.
