Prediction of Apophis's deformation-driven rotational evolution during its closest encounter to the Earth in 2029
Masatoshi Hirabayashi
In 2029, the near-Earth asteroid (99942) Apophis approaches the Earth within six Earth radii. This opportunity is one of the rarest natural experiments that we can use to better ch…
High-Speed Boulders and the Debris Field in DART Ejecta
Tony L. Farnham, Jessica M. Sunshine, Masatoshi Hirabayashi +44
On 26 September 2022 the Double Asteroid Redirection Test (DART) spacecraft collided with Dimorphos, the moon of the near-Earth asteroid 65803 Didymos, in a full-scale demonstratio…
The Dynamical State of the Didymos System Before and After the DART Impact
Derek C. Richardson, Harrison F. Agrusa, Brent Barbee +50
NASA's Double Asteroid Redirection Test (DART) spacecraft impacted Dimorphos, the natural satellite of (65803) Didymos, on 2022 September 26, as a first successful test of kinetic…
Diffraction modelling of a 2023 March 5 stellar occultation by subkilometer-sized asteroid (98943) 2001 CC21
Ko Arimatsu, Fumi Yoshida, Tsutomu Hayamizu +31
We present an analysis of a stellar occultation event caused by a near-Earth asteroid (98943) 2001 CC21, an upcoming flyby target in the Hayabusa2 extended mission, on March 5, 202…
BYORP and Dissipation in Binary Asteroids: Lessons from DART
Matija Ćuk, Harrison Agrusa, Rachel H. Cueva +10
The Near-Earth binary asteroid Didymos was the target of a planetary defense demonstration mission DART in September 2022. The smaller binary component, Dimorphos, was impacted by…
Lessons learned from NASA's DART impact about disrupting rubble-pile asteroids
S. D. Raducan, M. Jutzi, C. C. Merrill +4
We present a series of numerical simulations using a shock physics smoothed particle hydrodynamics (SPH) code, investigating energetic impacts on small celestial bodies characteris…
