2020 BE102 is a trans-Neptunian object in the scattered disc, around 350 kilometres (220 miles) in diameter. It was discovered on 24 January 2020, by American astronomers Scott Sheppard, David Tholen, and Chad Trujillo using the 8.2-meter Subaru Telescope of the Mauna Kea Observatories in Hawaii, and announced on 31 May 2021.[1] It was 111.2 astronomical units from the Sun when it was discovered, making it the third-farthest known Solar System object from the Sun as of May 2022[update], after 2018 VG18 (124 AU) and 2018 AG37 (~132 AU).[1][6]
