How do scientists tell the age of a moon rock?
Quick Answer
They count impact craters and use radioactive dating on returned samples when available. More craters generally mean an older surface.
The Full Story
On airless bodies like the Moon, surfaces accumulate impact craters over time, so crater density gives a relative age estimate. For more precise ages, scientists use radiometric dating of returned samples that contain long-lived radioactive isotopes. Apollo missions brought back lunar rocks between 1969 and 1972, giving researchers direct material to analyze. These techniques help reconstruct the history of the Moon and the early Solar System.
Key Facts
1.Apollo samples were returned from 1969 to 1972
2.Crater counting gives relative ages
3.Radioactive dating gives absolute ages
