(620094) 2016 AJ193

(620094) 2016 AJ193 (originally known as 2010 KV134) is a near-Earth object and potentially hazardous asteroid of the Apollo group, approximately 1.4 kilometres (0.87 mi) in diameter. It was discovered on 17 May 2010 by the Wide-field Infrared Survey Explorer (WISE) satellite, but was lost until it was reobserved on 16 January 2016. With an observation arc over 11 years, 2016 AJ193 has a well-determined orbit and trajectory through the year 2086. The asteroid's orbit is only potentially hazardous on a time scale of thousands of years. On 21 August 2021, the asteroid safely made a close approach to Earth from a distance of 0.0229 AU (3.43 million km; 2.13 million mi), or 8.92 lunar distances (LD). During closest approach, 2016 AJ193 reached a peak apparent magnitude of 14, visible to ground-based observers with telescope apertures of at least 20 cm (8 in). It is the largest asteroid that approached within 10 LD (3.8 million km; 2.4 million mi) of Earth in 2021. The asteroid received the permanent minor planet number 620094 by the Minor Planet Center on 7 April 2023. == References == == External links == Goldstone Radar Observations Planning: 2016 AJ193 and 2011 UC292, Lance A.
