Penumbra.
Earths shadow. If you were out in space behind the Earth, with the earth completely blocking out the sun to you, then you would be in Earths Umbra.
The umbra of the Earth's shadow during lunar eclipse is larger than the umbra of the Moon's shadow during a solar eclipse because the Earth is much larger than the Moon is; so, the Earth's shadow is bigger than the Moon'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.
