A Deep Dive into the Solar System’s Outer Frontier: Pan-STARRS Hunts for Distant Worlds

Holman et al. used Pan-STARRS1 data to search for distant solar system objects, identifying 692 candidates, including 109 new ones. They developed a novel detection method using synthetic populations and machine learning. Although Planet Nine was not found, the study narrowed its possible location to the galactic plane and demonstrated a powerful framework for future surveys.
