Solar eclipse 
                     Solar eclipse 
 
 
The Sun is 400 times larger than the moon 400 
times further away, which is why the two images 
appear from the sky as being the same. 
Astronomers can predict the eclipse due to the very 
stable orbits of earth and moon. So why is 
that  every month there is no eclipse? It is because 
the orbit of the Moon rotated a few degrees tilted 
towards north and south. So here size and distance 
cancel each other out thus the moon covering the 
sun. 
 
When the moon eclipses the sun, two kinds of shadows are casted 
 
1.smaller shadow known as the umbra 
2.larger shadow known as the penumbra 
 
 
There are 4 types of eclipse  
 
1.Total eclipse: when the moon covers the whole sun, it can only be seen if you are 
under the shadow of the umbra, which is why it creates an imaginary shadow line (the 
path of totality) that passes through the earth. 
2.Partial eclipse: moon covers or passes off-centre of the sun. 
 
3.Annular eclipse: it passes directly to the sun, but the moon seems to be too small 
for the moon to cover the sun, the moon's orbit is elliptical sometimes further away 
and sometimes closer to the earth. 
 
4.Hybrid Eclipse: It is when the position of the Moon between the Earth and the Sun 
is perfectly aligned and balanced that the curvature of the Earth plays the role of the 
Moon will be further away from some parts of the Earth along the eclipse path resulting 
in an annular eclipse on other parts of the Moon, which results in a total eclipse. 
 
 
 
A total solar eclipse occurs anywhere on earth every two years at any given point on 
earth every 400 years at any given event. Every time the moon orbits the earth once 
every 27.3 days A stage called the new moon phase has passed between the earth 
and the sun, and every time the new moon passes, it has a chance to block the sun 
most of the time the moon passes a little above or below the sun, But if the shadow of 
the moon is perfectly aligned, there will be a narrow path across the earth, and those 
in the shadow will see a total solar eclipse. 
 
 
Just like the night side of the earth, the sky is 
black and full of stars during the total eclipse. 
But the moon completely covers the surface 
of the sun, and does not block the outer 
atmosphere of the sun from its corona, which 
appears as a fiery ring around the dark disk of 
the moon. 
 
 
 
A solar eclipse occurs several times a year, but most often there are partial eclipses 
in which the moon is not quite aligned with the sun. And when the moon and the sun 
are perfectly aligned, the moon is usually too far away from the earth in its orbit to 
completely cover the sun, creating an annular eclipse. 
 
The sky remains bright during an annular or partial eclipse. Even on those rare 
occasions of total eclipse, the shadow of the moon is most likely to fall to 70% of the 
earth, and few people, if any, will see it. The eclipse in 2019, you can see that the fiery 
ring of the sun is due to the moon being further away from the sun. If our furry 
ancestors had taken the trouble to look up during the solar eclipse a hundred million 
years ago, he would not have seen the fiery crown of the sun. It would have been dark. 
 
Ultimately, the moon would have shifted too far from Earth to completely cover the 
surface of the sun. It is only during our little shimmering of earth's history that the moon 
is at the right distance to cause a total solar eclipse, but not a blockade of the solar 
corona. 
 
 
On December 26, 2019, when the moon is perfectly aligned with the sun, and the 
moon is close enough to the earth, it is a shadow across the earth, and if you happen 
to be in its narrow path, you will encounter one of the most awe-inspiring moments in 
the universe. Yet, as amazing as this phenomenon maybe, a total eclipse is one of the 
most dangerous and only specially tinted filters to be used to view the sun. The eclipse 
may make the sun to shame, but even the shame of the sun will seriously damage 
your eyes. Get yourself the best solar eclipse glasses for your eyes. 
 
CAUTION 
 
 
Looking directly at the sun 
can cause serious eye 
damage, fortunately, there are 
ways to enjoy the eclipse by 
using certified solar eclipse 
viewing glasses that are 1000 
times darker shades than 
conventional sunglasses. 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Just before the moon completely covers the sky, low-line valleys are the only ones 
seen where some light passes through, these bright shafts of light are known as Baily's 
beads, which disappear one after the other, and eventually, single beads of light 
remain known as the diamond ring seen seconds from completion. 
 
Once the last beads disappear and the moon fully covers the sun's surface, your solar 
eclipse is turning pitch black because it has reached totality, and at this point, none of 
the sun's rays reach your eye, it's the only time you're safe to take off your glasses. 
So you go get yourself the best solar eclipse glasses and experience the viewing of 
the solar eclipse.`
