Didymos
A near-Earth asteroid with a small moon, Dimorphos, and the target of the only deliberate attempt to move one: DART hit the moon in September 2022 and shortened its orbit around Didymos by 32 minutes, far more than the change anybody had predicted. It is here for that. ESA's Hera arrives at the end of 2026 to measure what a strike of a known energy actually did, which is the number the experiment was for.
