Question: is the moon made out of cheese?

Only if you’re Wallace or Gromit or a seriously deluded cheese lover. The moon is actually comprised mostly of material the same composition as terrestrial basalt! However lunar basalts generally contain much more iron and much higher concentrations of titanium. They were thought to have formed during large lunar volcanic eruptions 3-4 billion years ago when the moon was very young.
