How Solar Eclipses Are Formed 5, How Solar Eclipses Are Formed

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. There are three main types of solar eclipses: total solar eclipses, partial solar eclipses, and annular solar eclipses. Solar eclipses occur on the principle that parts of the Earth are obscured by the shadow of the moon.

The eclipse must occur on the New Year's Day, the first day of the lunar calendar. This is because only on that day will the Moon appear on the line between the Sun and the Earth, so that it is possible for the Moon to block the Sun and form a solar eclipse. Similarly, a lunar eclipse must occur on the 15th day of the lunar calendar.

The process of a solar eclipse can be divided into five phases, and only a total solar eclipse has the whole process, while a partial solar eclipse and an annular solar eclipse have no eclipse and no light. First Loss: The first outward cut between the Sun and the Moon, the moment when the west side of the Sun's photosphere just cuts into the east side of the Moon.

Eclipse: The first inward insection between the Sun and the Moon, when the Sun's photosphere is completely obscured by the Moon. Food:

The moment when the center of the Moon is at the least distance from the center of the Sun. Radiance: The second incision between the Sun and the Moon, when the Sun's photosphere has just emerged from the west side of the Moon.

Round: The second exosection between the Sun and the Moon, the moment when the Sun's photosphere has just completely left the back of the Moon. The first loss, the eclipse, the light and the circle are respectively called the first.

I. II.

Third, the fourth contact.

Occurs when the Moon orbits between the Sun and the Earth, when for parts of the Earth, the Moon is in front of the Sun, so some or all of the light from the Sun is blocked.

Sun, Moon Earth.

This arrangement creates a solar eclipse.

The moon, the sun, and the earth coincide in one line.

Solar eclipse formation: The moon is located between the earth and the sun, and the three are in the same straight line, at this time the moon blocks the sun's light, and the solar eclipse phenomenon occurs at this time.

A solar eclipse is a natural phenomenon that does not occur every day and only occurs under certain conditions. So how are solar eclipses formed? Let's give you a specific introduction.

01 Solar eclipse mainly refers to the movement of the moon to the middle of the sun and the earth, if the three are on a parallel line, the moon will block the light of the sun to the earth, and the black shadow behind the moon falls on the earth, that is, the moon runs to the middle of the sun and the earth, then the sun is blocked from the earth, which is the solar eclipse phenomenon.

02 When the sun's rays are completely or partially blocked by the moon, we see different scenes, so solar eclipses are divided into partial solar eclipses, total solar eclipses, annular solar eclipses, and total annular eclipses.

03 The Moon itself is much smaller than the Sun, and when it runs in a straight line and the Moon is close to the Earth, the Moon's shadow, that is, the shadow that falls on the Earth's surface, is just wide enough to cover the entire Sun. Seeing the Sun completely obscured on Earth is a total solar eclipse.

04 The Sun and the Moon only partially coincide, and the observer falls in the penumbra of the Moon, and the observer will see that part of the Sun is covered by the Moon's shadow, but the other part continues to glow, that is, the sunlight is partially obscured, which is a partial solar eclipse.

05 The moon itself is much smaller than the sun, and when it runs in a straight line and the moon is far away from the earth, it does not completely block the sun's rays, causing the center of the sun to be partially dark and the edges are still bright, which is an annular solar eclipse.

The formation of a solar eclipse is mainly the movement of the moon to the middle of the sun and the earth, when the three are in a straight line, the moon will block the light of the sun to the earth, and the black shadow behind the moon will fall on the earth, and the phenomenon of "solar eclipse" will occur at this time. In simple terms, solar eclipses are formed because light travels in a straight line in the same homogeneous medium.

How a solar eclipse is formedA solar eclipse, also known as a solar eclipse, is a natural phenomenon in which the Earth and the Sun are in a straight line, with the Moon in the center. The premise for this phenomenon is that the Moon is a satellite of the Earth and revolves around the Earth; And the earth revolves around the sun. In this case, the sun, the moon, and the earth will be in a straight line.

Solar eclipses are mainly divided into total solar eclipses, partial solar eclipses, annular solar eclipses, and total annular eclipses. When observing a solar eclipse, you need to be careful not to look directly at the sun, otherwise it will cause temporary blindness, and in severe cases, even permanent blindness.

The moon does not always move between the sun and the earth to have a solar eclipse, and two conditions need to be met for a solar eclipse to occur: first, a solar eclipse always occurs on the new sun, and not all new suns must have a solar eclipse, because the orbit of the moon and the orbit of the earth are not on the same plane; Second, both the Sun and the Moon move near the intersection of the white and ecliptic paths, and the Sun is at an angle from the intersection.

The schematic diagram of the position relationship between the Sun, the Earth, and the Moon in a "solar eclipse" is as follows:

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 dark 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. 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.

Precautions. 1. Do not be in other dangerous places such as streets and roads**, so as not to pay too much attention to the danger of life caused by the solar eclipse, and pay attention to safety when you are on the balcony** to avoid falling downstairs.

2. Due to the temperature caused by the solar eclipse, the earth's magnetic field changes, and the day is suddenly dark. As a result, some animals are not adapted to their physiological habits, such as dogs, cats and other pets should be leashed to avoid livestock panic and injury incidents.

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.
