The Double Asteroid Redirection Test (DART) mission was designed to demonstrate one possible way of deflecting such an object, targeting the non-threatening moonlet Dimorphos, which is about 560 feet wide. NASA quickly declared it a success after its initial analysis showed the planned collision shortened Dimorphos' orbit around Didymos, the larger of the two objects in the binary asteroid system. In a follow-up study published in 2024, a team at NASA's JPL reported that Dimorphos' orbital period had been trimmed by about 33 minutes, as its path was nudged roughly 120 feet closer to Didymos than before. The latest study now indicates that the whole binary system was affected, not just Dimorphos.
