The eclipse of the sun

1. Solar Eclipse
The eclipse of the sun

2. Solar Eclipse
• Solar eclipse occurs when the new moon comes between the Earth
and the Sun, covering all or some rays of the sun.
• Even though the sun is 400 hundred times wider than the moon it is
400 times farther than the moon. Therefore, the two objects appear
the same in the sky

3. Why the Eclipse do not occur everyday
• Earth and the Moon have very predictable orbits so why, isn’t there
an eclipse every month or day?
• The moon’s orbit is usually tilted few degrees north or south in
relation of the earth
• So, it always doesn’t eclipse
the sun .

4. Solar Eclipse
When the moon really eclipses the sun it casts two types of shadow
1. The smaller darker shadow known as the Umbra
2. And a bigger shadow know as the Penumbra

5. Types of Solar eclipse
There are for types of solar eclipse
Total solar eclipse:
It is the most spectacular
eclipse.
It occurs when the moon
fully covers the sun.
It can only be seen if you
are standing in the
umbra’s shadow.
The path by which the
total solar eclipse is seen
is known as the path of
totality
Partial solar eclipse:
People standing in the
penumbra’s shadow see
a partial solar eclipse.
It occurs when the moon
partially covers the Sun’s
surface.
Annular solar eclipse:
An annular eclipse occurs
when the moon passes in
front of the Earth of the
sun, unlike total solar
eclipse.
It appears too small to
fully cover the sun
It is because the moon is
sometimes closer to the
sun or sometimes farther
(please left click on the
Hybrid solar eclipse:
It occurs the moon’s
position is so finely
balanced between the
earth and the sun that
the curvature of the
earth plays a role.
It could sometimes result
in total solar eclipse or
sometimes annular
eclipse

6. Tip
• Don’t look at the SUN directly when the Solar eclipse is going on.
• It can burn and also cause loss of sight as the rays of the sun are very
powerful at this time.
• You should look at the solar eclipse with the special glasses
• If you don’t have the eclipse glasses you can even see it using a pin
hole viewer. Make sure you don’t look through the hole

7. Baily’s Beads
• Just before the moon fully covers the sun low-laying valleys will be
the only spots seen on the edge of the moon. The sunlight continues
to pass through these low laying valleys which are known as "BAILY'S
BEADS”. These beads start disappearing one-after-another.
• One last bead known as the “Diamond ring” remains showing that
you are few seconds away from seeing a total solar eclipse.

8. FUN FACT

Australia
