The activity that has most helped astronomers determine the age of the Moon is the **collection of lunar rock samples**.
The Apollo missions (particularly Apollo 11, 12, and 17) returned samples of Moon rocks and soil to Earth, which have been extensively analyzed using radiometric dating techniques. These analyses have provided critical insights into the Moon's formation and its age, estimated to be about 4.5 billion years. Other methods, such as placing retroreflectors on the lunar surface and deep space imaging, have contributed to our understanding of the Moon, but the direct dating of lunar samples has been the most significant for determining its age.
