The study of near-Earth asteroids (NEAs) is driven by both scientific and practical reasons. Because of their proximity to our planet, they can provide key information regarding the delivery of water and organic-rich material to the early Earth, and the subsequent emergence of life. On the other hand, these small bodies of the Solar System have non-negligible long-term probabilities of colliding with the Earth, and can be targets of future space exploration.
