  • The Taurid Resonant Swarm (TRS) contains debris in a 7:2 mean-motion resonance with Jupiter.
  • Fireball observations confirm TRS has many sub-meter-sized particles, but asteroid-sized object enhancement is unclear.
  • ZTF data suggests TRS may host ~100 Tunguska-sized and ~1,000 Chelyabinsk-sized objects.
  • Impact frequency estimated at less than once every 4 million years.
  • Future observations (e.g., Vera C. Rubin Observatory) could validate TRS asteroid constraints.
