Earth's shadow is the shadow that Earth itself casts through its atmosphere and into outer space, toward the antisolar point. During the twilight period, the shadow's visible fringe – sometimes called the dark segment or twilight wedge – appears as a dark and diffuse band just above the horizon, most distinct when the sky is clear.

Earth's shadow and the Belt of Venus at dusk, looking east from the Marin Headlands just north of San Francisco in October 2010. (Note: A thin layer of greyish cloud partially obscures the horizon in this image.)
A full moon rising, as seen through the Belt of Venus. A very small part of the Earth's shadow (dark blue) is also visible in this image, but the horizon here is too high for more of the Earth's shadow to be seen.
A total lunar eclipse on May 15, 2022, shows the reddish light falling on the Moon's surface.

The sky is an unobstructed view upward from the surface of the Earth. It includes the atmosphere and outer space. It may also be considered a place between the ground and outer space, thus distinct from outer space.
