Small near-Earth asteroids are important targets of study because not much is known about them. By characterizing the smallest of the bunch, scientists can better understand the population of objects from which they originate: large asteroids, which have (Image: NASA/JPL-Caltech) Small near-Earth asteroids are important targets of study because not much is known about them. By characterizing the smallest of the bunch, scientists can better understand the population of objects from which they originate: large asteroids, which have a much smaller likelihood of impacting Earth.
