What
Is A Solar Eclipse?
A
solar eclipse in when the Moon passes in front of the Sun casting a shadow on
the Earth (this is also known as an occultation).
As the Sun’s distance from
Earth is around 400 times the Moon’s distance and the Sun’s diameter is around
400 times the Moon’s diameter, the Sun and the Moon as seen from Earth appear
to be approximately the same size. There are several sorts of eclipses;
partial, annular and total.
Partial
Solar Eclipse: Occurs when the Moon does not line up with the Sun exactly only
partially obscuring it.
Annular
Solar Eclipse: When the Moon is further
from the Earth and/or the Earth is closer to the Sun the Moon will appear
smaller in comparison to the Sun so during an eclipse will not entirely cover
it appearing as a bright ring surrounding the Moon.
Total
Solar Eclipse: Occurs when the Moon completely obscures the Sun allowing the
fainter solar corona to be visible.
