*A solar eclipse
occurs when the
Moon passes
between the Sun
and the Earth so
that the Sun is
wholly or
partially
obscured.
*This can only happen during a new moon, when
the Sun and Moon are in conjunction as seen
from the Earth.

In ancient times, and in some cultures today, solar
eclipses have been attributed to supernatural
causes.
*There are four types of
solar eclipses:
* A "total eclipse" occurs when the Sun is completely obscured
by the Moon. The intensely bright disk of the Sun is replaced
by the dark silhouette of the Moon.
*An "annular eclipse" occurs when the Sun and
Moon are exactly in line, but the apparent size
of the Moon is smaller than that of the Sun.
* A "hybrid eclipse" is intermediate between a
total and annular eclipse. At some points on
the surface of the Earth it is visible as a total
eclipse, whereas at others it is annular.
* A "partial eclipse" occurs when the Moon only partially
obscures the Sun. This phenomenon can usually be seen
from a large part of the Earth.
*Spectacular solar eclipses are an extreme rarity within
the universe at large. They are seen on Earth because of
a fortuitous combination of circumstances that are
statistically very improbable.
Due to tidal acceleration, the orbit of the
Moon around the Earth becomes
approximately 3.8 cm more distant each
year.
A complicating factor is that the Sun will increase in size over this
timescale. This makes it even more unlikely that the Moon will be
able to cause a total eclipse.
