2019 SU3 is an Apollo (NEO) asteroid that has been added to the Risk List of the European Space Agency, since the asteroid may pass very close to Earth, about 9,700 km (6,000 mi) (based on current calculations), in about 65 years (year 2084).[1][2][3] According to astronomers, "It's small size of about 15 m (49 ft) would result in limited consequences even in case of impact."[2] Nonetheless, an impact by asteroid 2019 SU3 may be considered "one of the most significant impacts of the century".[2]
