What is the current status of asteroid detection and tracking efforts, particularly regarding different sizes of potentially hazardous asteroids?

According to NASA asteroid researchers, the detection efforts have been highly successful for large asteroids, with over 95% of them already cataloged and tracked. However, the situation becomes more challenging when dealing with smaller objects, particularly those larger than 100 meters across. These smaller asteroids pose a significant detection challenge despite still being large enough to cause substantial damage upon impact. The global astronomical community continues working to improve tracking capabilities for these smaller but potentially dangerous space objects.
