Q:

Why is the moon yellow?

A:

The moon is not yellow, but appears to look yellow when it is positioned high in the sky. For example, when the moon is low in the sky, it is being viewed through the most atmosphere and appears more red. As it moves higher into the sky, the amount of atmosphere that it is viewed through is lessened, making it look more yellow.

To see the true color of the Moon, it has to be viewed from space. This is the only way to view the moon without the atmosphere of the Earth causing it to look different colors. Pictures that are taken from outer space show the moon as gray. This is due to the elements out of which the surface of the moon is made. According to NASA, the surface of the moon is mostly made of iron, magnesium, oxygen, aluminum, silicon and calcium.

The rocks on the moon also differ in coloring depending on the elements from which they are made. Most of the darker rocks on the moon are pyroxene, while the lighter ones are plagioclase feldspar. There are some rocks that are brought to the surface from deep inside the Moon that are green in color.

  • Q:

    What is the meaning of a yellow moon?

    A:

    When the moon appears orange or yellow, it simply means that the observer is looking at it through more layers of atmosphere. Similar to the way in which the sun will look orange or red on the horizon, when the moon is low in the sky, the light from it will have to pass through more of the blue-absorbing atmosphere to reach the viewer's eye. By this time, only yellow, orange and red light will remain unabsorbed.
