The Moon's Role in Science
Insights into Earth's Formation
The Moon helps us learn about Earth's early days. Scientists believe the Moon formed after Earth hit a Mars-sized object billions of years ago. This idea is called the Giant Impact Hypothesis. Rocks from the Moon, brought back by Apollo missions, are like Earth's mantle rocks. This shows they share a common origin. The Moon moves away from Earth about 1.5 inches each year. This movement matches what the hypothesis predicts and shows how Earth and the Moon are connected.
The Moon is like a time capsule for studying planets. Its surface shows signs of old impacts and volcanoes. Unlike Earth, the Moon has no weather or tectonic changes. This keeps its surface mostly the same over time. Scientists can study the Moon to learn about the solar system's past. Recent missions have taught us about the Moon's minerals, shape, and heat history. These studies help us understand how planets change over time.
