We have developed a web-based application, COIAS (Come On! Impacting Asteroids), for the detection of Small Solar System Bodeis (SSSBs) from HSC-SSP (Hyper Suprim-Cam, Subaru Strategic Program) images. The primary goal of COIAS is to elucidate the orbital and taxonomic distribution of SSBS. In addition to advancing basic planetary science, COIAS contributes to planetary defense efforts by enabling the detection of near-Earth objects (NEOs). As of January 2025, COIAS has detected and reported over 210,000 new objects to the Minor Planet Center, with contributions from approximately 1,000 citizen scientists. Among these detections, 4,715 objects, including six NEOs, have been assigned preliminary designations. We present the current status of the search for SSSBs using COIAS.
