The growing precision of space observation has placed planetary defence at the centre of contemporary astrophysics. Among emerging candidates for mitigation planning, asteroid 2024 YR4 has prompted renewed attention to the role of nuclear disruption as a viable last-resort option against potential celestial collisions. Discovered in December 2024, this near-Earth asteroid follows an orbit that occasionally brings it within the Earth–Moon system. Though the risk of an Earth strike has been excluded, ongoing analyses reveal a small but measurable probability of a lunar impact in 2032. Current studies now evaluate how nuclear-based intervention could prevent secondary hazards, including debris clouds that threaten satellites and human spaceflight. A study by arXiv , titled Space Missio
