Labels:text | screenshot | circle | moon OCR: MAP THE MOON ASTRONOMICAL SYMBOL THE MOON IS THE EARTH'S only natural satellite. It is a rocky sphere with a diameter about one fourth that of the Earth. The Moon emits no light of its own, but we can see it when it reflects sunlight toward us. It is a lifeless and dusty place with no water. It also has no atmosphere because its surface gravity is too weak to hold on to gas particles. The lunar surface is scarred by thousands of craters. Volcanic lava has seeped through the lunar crust into some of the largest craters, forming maria, or "seas."
