2019 SU3 (SPK-ID: 3856703) is an Apollo (NEO) asteroid, discovered 23 September 2019, that was briefly listed on the Risk List of the European Space Agency. With a 18 day observation arc, the nominal orbit passes 0.02 AU (3,000,000 km; 1,900,000 mi) from Earth on 27 September 2084.[2] It was removed from the Sentry Risk Table on 12 October 2019.
Based on calculations with a shorter observation arc, the asteroid could have passed very close to Earth, about 9,700 km (6,000 mi), in mid-September, 2084.[3][5][6][7] According to astronomers, "Its small size of about 15 m (49 ft) would result in limited consequences even in case of impact."[3]
