An eclipse is a passage of an astronomical
body through the shadow of another.
The term is usually employed for solar and
lunar eclipses, which may be either partial
or total. A solar eclipse occurs when the
Moon passes in front of the Sun as seen from
Earth, and can happen only at new Moon.
During a total eclipse the Sun's corona can
be seen. A total solar eclipse can last up to
7╜ minutes. When the Moon is at its farthest
from Earth it does not completely cover the
face of the Sun, leaving a ring of sunlight
visible. This is an annular eclipse. Between
two and five solar eclipses occur each year.
A lunar eclipse occurs when the Moon passes
into the shadow of the Earth, becoming dim
until emerging from the shadow.
Lunar eclipses may be partial or total, and
they can happen only at full Moon. Total
lunar eclipses last for up to 100 minutes,
the maximum number of Total lunar eclipses
each year is three.
