2020 BE102 is a trans-Neptunian object in the scattered disc, with a diameter of approximately 350 kilometres (220 miles). It was discovered on 24 January 2020, by American astronomers Template:Scott S. Sheppard, Template:David J. Tholen, and Template:Chad Trujillo using the Template:Subaru Telescope of the Template:Mauna Kea Observatories in Hawaii, and announced on 31 May 2021.[1] It was 111.2 astronomical units from the Sun when 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]
