Anya randomly asked how many footballers it would take to make the weight of the Earth. Well, that’s quick enough to calculate. Average footballer is just under 80 kg … rounded up because the number is going to be *so* huge anyway.

That would be just over 74 sextillion footballers. 74,650,000,000,000,000,000,000! Which is a *lot* of people. To get an idea of order of magnitude, I divided by the population of Earth. We’re talking ten *trillion* times more people that we’ve got today.

The moon, on the other hand, is a mere 123 billion times more people than we’ve got today.
