What is the difference between a Solar and a Lunar Eclipse?If a Solar Eclipse is when the Moon goes in front of the sun, what is a Lunar Eclipse?

During a solar eclipse, the sun is eclipsed, or blocked
from view. This occurs because the moon passes between the sun and the earth. Solar
eclipses can be partial, total, or annular, a form of eclipse where the central disk of
the sun is blocked but the outer edge, or corona, stays in
view.

During a lunar eclipse, the moon is eclipsed, or
blocked from view. This happens when the earth passes between the sun and the moon, and
casts a shadow on the moon. The only time this can occur is during the full moon phase,
when the sun, earth, and moon are in a straight line relative to one
another.

Neither type of eclipse happens terribly often
because the orbits of the earth and moon are elliptical rather than circular, and the
orbit of the moon sits at an angle relative to the orbit of the earth around the sun.
Since an eclipse only occurs when the alignment is perfect, we only have them once in a
while.
