Just like the Earth the moon passes through the same debris fields we do. In March 2013 a meteor hit the moon and was bright enough to be seen from Earth. I learned from this video that NASA is studying meteor showers on the Moon so they can advise lunar settlers when to stay indoors.
Just like the Geminids the debris fields from comets and others of unknown origins are predictable. I love that a concept from star gazing applies to the exploration of our solar system!
