the moon. From ancient times to today, the moon remains a perpetual source of wonder for the inhabitants of Earth, just one quarter earth size. Our moon is small compared to other, more spectacular bodies in the universe. But since it's only 240,000 miles away, a relatively short distance when, compared with the vastness of space, nothing looms larger in the night sky. Many scientists believe that the moon formed about 4.6 billion years ago, when a huge asteroid struck the earth with such force that rock and debris were shot into orbit around the planet like the rings of Saturn. Over time, this cloud of fragments came together to form our moon. Mhm. With little atmosphere to protect it, the moon has been and continues to be bombarded by space debris. The evidence appears all over its dusty surface.
