It initially looked like a typical fast-moving small asteroid, but additional observations over the next couple of days allowed its orbit to be computed\u00a0fairly accurately. The orbit calculations revealed beyond any doubt that this body did not originate from inside the Solar System, like all other asteroids or comets ever observed,\u00a0but instead had come from interstellar space. Although originally classified as a comet, observations from ESO and elsewhere revealed no signs of cometary activity after it passed closest to the Sun in September 2017.
