2022 OB5

is a small near-Earth asteroid that passed within from Earth on 5 August 2022. It was the primary target of AstroForge's Brokkr-2 mission, which launched alongside IM-2 in February 2025, and was planned to reach the asteroid around December 2025. Communication issues ultimately prevented the mission from visiting the asteroid. 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.
