 Schematic diagram of the shadow cast by the
Earth. Within the central umbra shadow, the Moon is totally
shielded from direct illumination by the Sun. In contrast, within
the penumbra shadow, only a portion of sunlight is blocked.
 As viewed from Earth, the Earth's shadow can
be imagined as two concentric circles. As the diagram illustrates,
the type of lunar eclipse is defined by the path taken by the Moon
as it passes through Earth's shadow. If the Moon passes through the
outer circle but does not reach the inner circle, it is a penumbral
eclipse; if only a portion of the Moon passes through the inner
circle, it is a partial eclipse; and if entire Moon passes through
the inner circle at some point, it is a total eclipse.
