Over the last century seismic and geodetic methods have revolutionized our understanding of the internal structure of the Earth, of the Moon, and of Mars. The same techniques can be applied to measure an asteroid’s physical properties and internal structure. This information is critical for understanding the evolutionary history of asteroids, and for planetary defense (to understand the damage that may cause upon impact, and to evaluate mitigation strategies).
