Asteroids Impacting the Solar System Planets and the Moon. III. Real Impacts from Known Objects and LSST Discovery Predictions
Qifeng Cheng, Daniel Scolnic
Impact rates predicted using pre-impact source-population models and those inferred from observations disagree by a factor of a few to across the Solar System planets and…

Asteroids Impacting the Solar System Planets and the Moon. II: Comparison with Observational Impact Records
Qifeng Cheng, Daniel Scolnic
Planetary impact rates are difficult to infer from observations alone because impacts are rare, observational records are target-dependent, and converting observed flashes, bolides…

Asteroids Impacting the Solar System Planets and the Moon. I. Collision Rates from N-body Simulations
Qifeng Cheng, Daniel Scolnic
Previous studies have shown a mismatch between the simulated rate of asteroids impacting the Earth and the observed rate, posing an important problem for planetary defense. Extendi…
