<p>I've noticed that when I look into the sky at night, sometimes the moon appears very large near the horizon. Sometimes it also looks like it has a yellow tint. </p>

The Moon or Sun near the horizon looks reddish for the same reason the sky is blue. Blue light is preferentially scattered by the atmosphere. When the Moon or Sun is near the horizon, its light travels through more of the atmosphere; the scattering of the blue light leaves just the reddish light.

Why does the Moon seem larger when it is close to the horizon?
