 This impact occurred between December 2003 and November 2005. The main crater itself is only 23 meters across, but the impact event created markings spreading more than a kilometer outward. The interior stands out as blue because the impact excavated a cavity into rocks below the surface that has a different composition than the overlying dust. Some distant dark-toned spots and streaks were created when ejecta from the main crater flew out and re-impacted the surface, producing chains of secondary craters.

 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.
