Moon may be millions of years older than previously calculated
Analysis of hafnium and tungsten in Apollo 17 samples suggests the moon formed 50 million years after the solar system
A new study involving samples collected during the last mission to the moon has suggested that the satellite was formed roughly 50 million years after the formation of the solar system. The researchers reached their estimate by investigating the ratio of hafnium to tungsten-182 in the fragments of the lunar mantle, collected by the Apollo 17 mission.
