Can we live on the moon?


Although you might think it would be cool, humans could not live on the moon! (Maybe one day in the future...) The moon has almost no atmosphere, so there's no air for us to breathe. There is no water on the moon either, and we need to drink water to survive. Days and nights on the moon last over two weeks long! This means the surface reaches super hot and cold temperatures: as high as 123°C or as low as −233°C.

Someone also wanted to know where the moon came from. We know that the moon formed about 4.5 billion years ago, but scientists don't know for sure how it happened exactly. Right now, there are four major theories, and the one most people agree on is the giant-impact hypothesis. This theory suggests that a planet about the size of Mars struck Earth. This vaporized the outer layers of Earth. The debris from the impact could have joined together through the power of gravity to form the moon. Whatever happened, we're glad it's here! Our night sky just isn't the same without it.
