Probably everyone in life has ever heard or even seen such a phenomenon as a solar eclipse. And did
you ask yourself the question, where does it come from, what are the reasons for its occurrence, in
general, what is this phenomenon of nature?
From ancient times, solar and lunar eclipses, like other rare astronomical phenomena, such as the
appearance of comets, were perceived as negative events. People were very afraid of eclipses, since
they occur rarely and are unusual and frightening phenomena of nature. In many cultures, eclipses were
seen as harbingers of misfortunes and catastrophes (especially in the case of lunar eclipses, apparently
because of the red color of the shaded Moon associated with the blood). In mythology, eclipses were
associated with the struggle of higher forces, one of which wants to break the established order in the
world ("extinguish" or "eat" the Sun, "kill" or "pour blood" on the Moon), and the other – to preserve it.
The beliefs of some peoples demanded complete silence and inaction during eclipses, others, on the
contrary, active witchcraft to help "the bright forces".
Saros (the cycle, whose length is 6585.3 days, or 18 years, 11 days and just under 8 hours) was known to
astronomers of ancient Egypt and Babylon. Thanks to Saros, ancient astronomers accurately predicted
eclipses, without having a clear idea of ??the celestial mechanics, nor computing devices. Indeed, in order
to predict the date and time of the eclipse, it is sufficient to have a list of the last occuring eclipses and
add to the date and time of each of them an integer number of Sarosses. The prediction of lunar eclipses
in general is not difficult. With solar eclipses everything is somewhat more complicated, since it is
necessary to take into account that when the eclipse is repeated through Saros its strip will pass in
another place, and be able to calculate this place. To facilitate the calculation of solar eclipses, ancient
scientists used the triple Saros – period equal to 19755,
The predictions of the Saros eclipses give acceptable accuracy within plus or minus 300 years, at more
remote times, failures begin, caused by the accumulation of errors.
We all know the only living planet is Earth which like any other planet revolves around the Sun. And like
any other planet, it also has its own satellite which is the Moon. The relationship between the Sun, Earth
and Moon yields into the two phenomenons of nature, Solar eclipse and Lunar eclipse. Before we
proceed any further, you should understand that what is eclipse? An eclipse is the shadowing of any
celestial body due to any other celestial body. It is a temporary obscuration which occurs due to
constant movement of astronomical bodies.
Let’s talk about Lunar Eclipse. Lunar eclipse occurs when the moon enters the cone of the shadow cast
by the earth. The diameter of the Earth's shadow spot at a distance of 363,000 km (the minimum
distance of the Moon from the Earth) is about 2.5 times the diameter of the Moon, so the Moon can be
shaded entirely. And for the solar eclipse, during new moon, the moon casts its shadow on sun by
coming in between the Sun and the Earth.
When the shadow of the Earth falls on the moon, and it disappears from the horizon. The Earth rotates
around the Sun, and the Moon revolves around the Earth. Both these processes occur simultaneously. If
for a few minutes the Moon, the Earth and the Sun are on the same line, the eclipse begins. A total solar
eclipse is a very rare and dramatic event. During a total solar eclipse, one gets the impression that some
huge monster loses the Sun after the piece. When the Sun disappears, the sky becomes dark and the
stars are visible in the sky.

Probably everyone in life has ever heard or even seen such a phenomenon as a solar eclipse. And did you ask yourself the question, where does it come from, what are the reasons for its occurrence, in general, what is this phenomenon of nature?

The first such phenomena were noticed by mankind in the very antiquity. Previously, people at the sight of a solar eclipse were lost and felt a wild terror before this mysterious phenomenon. As a rule, among ordinary people there was an opinion that at that moment some terrible dragon was trying to destroy the sun and it must be protected. Since the solar eclipse does not last long, the plan of local residents has always worked. They armed themselves with military weapons and went to the “war”, after the streets became brighter, people returned to their homes calm and contented that they drove away the evil spirits and saved the sun. It is also known that the first ever eclipse in history was during the reign of Chung-Kang, the fourth emperor of the Hen dynasty. It is to this period that a recording is recorded in one of the books of ancient China – “Shujin” (“The Book of History”). The date of the solar eclipse was established only in the nineteenth century – October 22, 2137 BC. e.

We all know the only living planet is Earth which like any other planet revolves around the Sun. And like any other planet, it also has its own satellite which is the Moon. The relationship between the Sun, Earth and Moon yields into the two phenomenons of nature, Solar eclipse and Lunar eclipse. Before we proceed any further, you should understand that what is eclipse? An eclipse is the shadowing of any celestial body due to any other celestial body. It is a temporary obscuration which occurs due to constant movement of astronomical bodies.

The duration of such an astronomical phenomenon is only a few minutes, since the speed of motion of the shadow of the moon is 1 km / s, at least. The total cycle of the eclipse is 6 hours, and its origin takes in the western part of the earth at sunrise, and ends in the eastern part at the approach.

Naturally, with a partial eclipse, you will not see the same effect as from a total eclipse. Also, astronomers discern an annular solar eclipse, the essence of which is that the Moon passes the Sun and in diameter less than the last, it turns out that during the eclipse you can see the Sun along the circumference.

When the shadow of the Earth falls on the moon, and it disappears from the horizon. The Earth rotates around the Sun, and the Moon revolves around the Earth. Both these processes occur simultaneously. If for a few minutes the Moon, the Earth and the Sun are on the same line, the eclipse begins. A total solar eclipse is a very rare and dramatic event. During a total solar eclipse, one gets the impression that some huge monster loses the Sun after the piece. When the Sun disappears, the sky becomes dark and the stars are visible in the sky. The air is rapidly cooling down. Soon, from the sun, there is nothing left but a thin glowing ring, as if hanging in the sky, we see that part of the flaming solar corona.
