The Rock That's Been Following Earth For 100 Years Is Not What We Thought

A Chinese spacecraft just reached a rock that has shadowed Earth for a century — and the theory that it's a piece of our own Moon is falling apart at the worst possible moment. Kamo'oalewa is roughly the width of a football field, spins once every twenty-eight minutes, and hides in the glare of the Sun. For four years the leading theory said it was a fragment blasted off the Moon. Then the James Webb Space Telescope looked closer — and complicated everything. Now China's Tianwen-2 mission is on station, gathering the sample that could finally settle it. This is the full story: what the rock is, why it matters, and the blind spot it exposes over our heads. This is a deep-dive documentary. Settle in.
