Treasure Hunt in Earth's Attic
Clues to Earth’s history are valuable treasures. |

The Moon has treasures of its shared history with Earth, going back 4.5 billion years. Early in our solar system’s history, a small planetary body — about half the size of Earth — slammed into our home planet. The Moon formed from the debris of that collision and has evolved alongside Earth since that time.

Just as an attic stores heirlooms that record your family’s history, the Moon preserves the history of Earth and the rest of our own solar system.
