On 19 October 2017 an Interstellar Object was spotted passing through our Solar system, the first of its kind to be discovered. With little warning, astronomers had only a few days to study it before it became too faint for detailed investigation, even when using the world’s largest telescopes. Studies revealed a body that matched some of our expectations, but that differed significantly in other aspects. This talk will cover how it was discovered, and what we have learned so far.
