One of the defining moments in planetary astronomy in 2017 is that this is the year we discovered the first astronomical object to enter the Solar System from interstellar space. Now known as `Oumuamua (Hawaiian for "scout"), the object was discovered by the Pan-STARRS survey team in Hawaii on October 19th.
