A solar eclipse is formed when the shadow of the Moon is cast onto Earth. Due to the rotation of the Moon, the shadow will form a long ribbon called a solar eclipse belt, which is generally referred to as a total or annular eclipse. That is, the width of the moon's umbra or pseudo-umbra.
The total eclipse zone is a narrow path with a width of only two or three hundred kilometers and a length of about thousands to 10,000 kilometers, because the orbit of the moon is not a strict circle, but a slight ellipse, the distance between the moon and the earth is sometimes close and far away, and the width of the lunar shadow is also wide and narrow, and sometimes the width of the total eclipse zone is even only a few thousand meters. 30 miles is equivalent to nearly 50 kilometers, and it is indeed possible. But the width of the eclipse zone is generally about 200 km.

All the animals stopped chirping, and there was a dead silence all around. During a total solar eclipse, a narrow band of light appears around the horizon because the observer is not directly under the moon's shadow and the Earth is at a certain distance from the moon.
Before the advent of modern atomic clocks, astronomers, through ancient records of solar eclipses, found that the phenomenon of solar eclipses caused the Earth's rotation cycle to slow down by seconds each century.
Before and after the total solar eclipse, a strange phenomenon will attract the attention of many international scientists and **: the gravimeter data on Earth suddenly decreases. This phenomenon occurs due to the fact that during a solar eclipse, the Moon is between the Earth and the Sun, which weakens the Sun's gravitational field, and the Moon's gravitational force kicks in.
When a total solar eclipse occurs, light casts the shadow of a crescent moon through the gaps in the leaves. At this time, animals often behave abnormally, such as birds returning to their nests and nocturnal creatures such as bats come out to move, and the local temperature usually drops by at least 20 degrees Celsius.
When 99% of the sun's surface is covered, people will see the phenomenon of morning and dusk shadowing. Although there is currently no evidence that solar eclipses have an effect on people's bodies, this natural phenomenon has a serious impact on people's psyche. For thousands of years, almost all civilizations on Earth have seen solar eclipses as harbingers of disaster, and many times in history they have caused social unrest.

No, because these two phenomena cannot occur at the same time.
Since the distance between the Earth and the Moon is fixed, and their distance from the Sun is uncertain [the orbit is elliptical], if the three bodies are in the same straight line, the annular solar eclipse will be seen when the distance between the Earth and the Sun is large (in the pseudoumbra region), and the full solar time will be seen when it is smaller, so it is impossible for them to appear at the same time.
Both total and annular solar eclipses are solar eclipses, but due to the difference in distance between the Earth and the Moon, an annular solar eclipse is formed when the Moon is far away from the Earth, and a total solar eclipse is formed when it is closer.
The type of eclipse is related to the structure of the moon's shadow and the position of the Earth in the moon's shadow at the time of the eclipse.
There are three areas of the moon's shadow: the cone-shaped dark area that extends directly from the moon is the moon's umbra, where no sunlight can reach it; The cone-shaped dark area extended by the umbra is called a pseudoumbra and can only be reached by light rays from the surrounding edges of the sun; The diagonal area around the umbra and pseudoumbra is the penumbra, which is partially accessible by the sun's rays.

Partial solar eclipse refers to an astronomical phenomenon in which when the Moon orbits between the Earth and the Sun, and when the Earth orbits to the penumbra of the Moon, part of the Earth is covered by the penumbra on the outer side of the Moon's shadow, and part of the Sun seen in this area is blocked by the Moon. A partial solar eclipse is a common astronomical phenomenon. On June 2, 2011, Beijing time, a partial solar eclipse was observed in northeast China.
When the Moon orbits the Earth until the Sun rises and sets almost at the same time as the Sun and the Earth, the Moon cannot be seen from the Earth, which is called the New Year, and the solar eclipse phenomenon occurs at the New Year. The cycle of the new is about a few days. Therefore, a solar eclipse occurs only when the Sun is within a certain angle of the intersection of the two orbital planes.
-
It is completely impossible to see an annular solar eclipse.
Because the Sun and Earth are far away, the Sun will appear smaller, smaller than the Moon, so the apparent diameter of the Moon will always be able to block the entire Sun, and an annular eclipse will not occur.
-
When an annular solar eclipse occurs, the outer circle of the sun becomes smaller, and it all goes inside, so the annular solar eclipse also becomes a total solar eclipse.
-
A total solar eclipse is unlikely because the sun looks smaller as the distance increases.
The Earth is big and Mercury is small. The average radius of the Earth is 6,371 kilometers, and Mercury is the smallest large planet in the solar system, and the average radius of Mercury is only 2,440 kilometers, which is only two-fifths of the Earth.

For girls who love beauty, niacinamide.
Absolutely no stranger, many girls know the whitening effect of niacinamide, so many women will prepare some niacinamide and use it when skin care and compressing, so as to make their ** look new, to improve the texture and brighten the effect of whitening belly, so when is niacinamide used? Is niacinamide only available at night? Let's introduce it to you! >>>More
Of course, when a total lunar eclipse occurs on Earth, the Moon enters the shadow of the Earth, which means that the Moon will not be able to reflect the sun's rays, and a lunar eclipse will occur on Earth. But for observers on the Moon, the Earth blocks the sun's rays, which is a total solar eclipse for the Moon, because the Earth is larger than the Moon, so the eclipse on the Moon will last longer than on Earth. If there is a partial lunar eclipse on the earth, there will be a partial solar eclipse (on the moon) but there will be no annular eclipse, and when a solar eclipse occurs on the earth, there will also be a "terrestrial eclipse" on the moon, but it will never be a "total eclipse" because the moon is not big enough to block all the sun's rays.
