Some planets have lots of moons. Others have none. Earth has just one moon, but it’s a really great one. It can glow bright and white and sometimes it’s shaped like a big round ball. Other times it’s skinny like the white tip of a fingernail. Makes you wonder, why does the moon look the way it does? We asked Preston Dyches from NASA’s Jet Propulsion Laboratory to help us find the answer. Got a question orbiting around your brain?
