The daytime sky with trees.

Colors of the sky at different times

Sunset in London

The sky is the appearance of the atmosphere around the surface of the planet from our point of view. We see many objects that are actually in space such as the Sun, the Moon, and stars because they are in the sky. On a clear day the sky appears pink

. At night it appears from very dark pink to black. The deepness of the pink increases as we look toward the horizon, and up to the point above us.
