When the moon passes through the earth's penumbra there is a partial eclipse of the moon for those on the side of the earth facing the moon. If it passes through the umbra, the eclipse is total.
Lunar eclipse: Earth makes the shadow; the moon passes through it.Earth's shadow is large enough to darken the shole moon at the same time.Solar eclipse: Moon makes the shadow; earth passes through it.Moon's shadow is not large enough to darken the whole earth at the same time ...it causes only a small dark spot, that moves along the surface as the earth turns.
A lunar eclipse occurs when the full moon passes through the Earth's shadow.
The umbra of a moon is the completely shaded, or hidden from light, part of the moon. The penumbra of a moon is the part that is only partially hidden, or shaded from light. The antumbra is completely in the light, and no shadows are cast upon it.

A partial lunar eclipse occurs when the Moon partly passes through the Earth's umbra. A total lunar eclipse occurs when the Moon fully passes through the Earth's umbra. When the Moon only passes through the penumbra, there is only a subtle darkening of its surface. The umbra and the penumbra are parts of the Earth's shadow.

It is the Prime Meridian.
The moon darkens because it passes through Earths shadow.
More specifically, a total lunar eclipse occurs when the moon passes through the umbra, the darker part of the shadow.
nearby areas that are in the penumbra experiences a partial eclipse. a partial eclipse also occurs when the umbra completely misses earth and only the penumbra passes over.
The earth's orbit passes through the orbits of cometary debris which manifest themselves as meteorite showers.
