The umbra of earth's shadow is about 1.4 million km (860,000 mi) long and points directly away from the sun. Distances and sizes are not to scale.
A partial lunar eclipse occurs when the moon passes partly into the umbra of earth's shadow.
Sun, earth, and moon are not perfectly aligned during a penumbral eclipse. The umbra, penumbra and antumbra are three distinct parts of a shadow, created by any light source after impinging on an opaque object.
