2022 OB₅ is a small near-Earth asteroid that passed within 0.00679 AU (1,016,000 km) from Earth on 5 August 2022.^[2] It was the primary target of AstroForge's Brokkr-2 (Odin) mission, which launched alongside IM-2 in February 2025, and was planned to reach the asteroid around December 2025.^[3] Communication issues ultimately prevented the mission from visiting the asteroid.^[4] It was selected for the mission as it is suspected to be a metallic M-type asteroid suitable for space mining in the future. However, its actual spectroscopic composition is not yet known.^[5]^[6]
