Description
The LSST is revealing a previously unexplored population of ultra-fast-rotating sub-kilometer asteroids in the main belt. Several recently identified targets, including 2025 MN45, 2025 MK41, 2025 MV71, and 2025 MG56, show rotation periods of just a few minutes despite sizes >0.5 km, challenging current rubble-pile cohesion models. We aim to perform targeted photometric follow-up to verify rotation periods, characterize lightcurves, and improve size estimates by combining observations at opposition with LSST data. This work will clarify their physical properties, internal structures, and formation histories, providing critical insights into asteroid cohesion limits and spin evolution.
