Explanation

The Moon is approximately 4.53 billion years old, formed shortly after Earth's formation from debris after a Mars-sized body impacted early Earth (the Giant Impact Hypothesis). Lunar samples brought back by Apollo missions have been radiometrically dated to confirm this age. The Moon formed within about 50 million years after the Solar System's formation.
