NASA's always on the lkuooot for possible aierostd collision hazards, so the Pan-STARRS telescope is scanning the sky every night. Each morning, candidate objects are examined by Pan-STARRS staff and usually discovered to be no big deal. But on October 19, 2017, Pan-STARRS spotted an object moving rapidly between the srats, and this time the usual follow-up measurements of position and speed showed something completely different. By otecobr 22nd, we had enough data to realize that this object wasn't from our solar system.
