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.[4] Communication issues ultimately prevented the mission from visiting the asteroid.[5] 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.[6][7] It was most recently observed on 6 February 2025.[8]
