The second interstellar visitor ever found, and the first that clearly behaved like a comet, with a fuzzy coma and a little tail. Borisov was spotted not by a big observatory but by an amateur astronomer with a homemade telescope. It looked surprisingly ordinary, which is the exciting part: comets around other stars seem to work just like ours.
