What Color Is the Moon?
If you look up close to the moon’s surface, what color is the moon?
Well, the moon doesn’t emit light. Instead, it reflects light from sunlight.
This light that bounces off the moon’s surface into our eyes is mostly grey.
Now, you know the moon is grey… What types of rocks can we find on the moon? And what are the dark spots on the moon?
Rocks on the Moon
There are 4 dominant types of rocks on the moon:
- Mare basalts are black volcanic basalts common in the lunar maria. These are the flood basalts that formed during a period of volcanic activity 3 billion years ago.
- Breccia aren’t rounded. Instead, these types of rocks are sharp and jagged. They formed during meteoric collisions and are commonly found in the moon’s craters.
- Anorthosite is common on lunar highland areas. They formed in lunar magma oceans experiencing frequent melting. These rocks are the oldest on the moon’s surface.
- Regolith is shattered rock on the moon’s surface. Most of the moon’s surface is covered with meters of this dusty type of material.
What are the dark spots on the Moon?
Long ago, early scientists believed they could see oceans on the moon so they called them “maria”. But the dark stretches on the surface of the moon were not oceans at all.
What the lunar maria actually turned out to be were flat flood basalts. These formed during a period of volcanic activity 3 billion years ago.
There is no water on the moon. This means there is no chance that humans can ever colonize the moon
The moon does not have plate tectonics so nothing changes on the moon. That’s why we characterize the moon as a “dead” planetary body.
