Dimorphos has recently made headlines due to NASA's DART mission, which aimed to impact the asteroid to test planetary defense techniques. The impact caused unexpected changes in Dimorphos' orbit, shape, and composition, leading to new discoveries about this small asteroid satellite.
Dimorphos was discovered in 2003 and is the minor-planet moon of a synchronous binary system with the primary asteroid 65803 Didymos. Initially designated as S/2003 (65803) 1, Dimorphos has been a subject of scientific interest due to its unique status as a satellite of a larger asteroid. The recent revelations from the DART mission have provided researchers with valuable insights into the dynamics of asteroid systems and the potential for altering their trajectories in the future.
