How is helium on the moon different from the helium found on earth?

Helium on the Moon primarily comes from the solar wind, which continuously bombards the lunar surface, resulting in the accumulation of helium-4 isotopes in the regolith. In contrast, the helium found on Earth is mostly produced through the radioactive decay of heavy elements in the Earth's crust and is often extracted from natural gas deposits. Additionally, lunar helium is more challenging to collect and utilize due to the Moon's lack of atmosphere and low gravity, which affects its retention and concentration.
