In a remarkable blend of astronomy and artificial intelligence, scientists have harnessed data from the European Space Agency's Gaia mission to unravel the enigmas of asteroid rotations. Utilizing AI modeling, the research has unearthed that an asteroid's spin rate is largely dictated by the frequency of cosmic impacts it has endured.

An intriguing finding from the study is the identification of a rotational velocity gap. This suggests a balance point where the forces from collisions and the internal friction within the asteroid reach an equilibrium. This discovery implies that many asteroids are not solid monolithic bodies but are instead conglomerates of loose rubble.

This characterization of asteroids as 'rubble piles' carries significant implications for planetary defense strategies. If an asteroid were targeted by a deflection mission such as NASA's DART, its response might differ considerably from that of a solid rock.

The research, combining the prowess of AI with Gaia’s comprehensive data set, marks a significant advancement in our understanding of these celestial bodies. It also highlights the pivotal role AI plays in interpreting astronomical data and furthering space exploration.

The broader implications of these findings are substantial for future space missions and the strategies employed to protect Earth from potential asteroid impacts.
