Back side states:
"THE MOON" (LUNA) -- Little Earth has only one moon, but a planet-sized one nearly as large as Mercury. Named Luna, but more commonly called simply "The Moon" on Earth.
It has about the same land area as Africa, and keeps one side forever facing its mother planet as a distance of 385,000 km / 239,000 miles. With its own interesting geography, stark scenic beauty, and dozens of famous spacecraft landing and crash sites, Luna is a tourists delight. Visit the Moon Soon!
