We model the outcomes of catastrophic disruptions on small, gravity-dominated natural satellites, accounting for the tidal potential of the central body, which is neglected in clas…
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…
Satellite formation around the largest asteroids
Kevin J. Walsh, Ronald-Louis Ballouz, Harrison F. Agrusa +3
Satellites around large asteroids are preferentially found among those with the most rapid rotation and elongated shape. The taxonomic statistics are similarly skewed; in total, 13…
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…
Spin states of X-complex asteroids in the inner main belt -- I. Investigating the Athor and Zita collisional families
D. Athanasopoulos, J. Hanuš, C. Avdellidou +14
The aim of our study is to characterise the spin states of the members of the Athor and Zita collisional families and test whether these members have a spin distribution consistent…
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…
The Yarkovsky effect on the long-term evolution of binary asteroids
Wen-Han Zhou, David Vokrouhlicky, Masanori Kanamaru +4
We explore the Yarkovsky effect on small binary asteroids. While significant attention has been given to the binary YORP effect, the Yarkovsky effect is often overlooked. We develo…
Dimorphos orbit determination from mutual events photometry
Peter Scheirich, Petr Pravec, Alex J. Meyer +6
The NASA Double Asteroid Redirection Test (DART) spacecraft successfully impacted the Didymos-Dimorphos binary asteroid system on 2022 September 26 UTC. We provide an update to its…
Physical properties of asteroid Dimorphos as derived from the DART impact
S. D. Raducan, M. Jutzi, A. F. Cheng +39
On September 26, 2022, NASA's Double Asteroid Redirection Test (DART) mission successfully impacted Dimorphos, the natural satellite of the binary near-Earth asteroid (65803) Didym…
Direct -body simulations of satellite formation around small asteroids: insights from DART's encounter with the Didymos system
Harrison F. Agrusa, Yun Zhang, Derek C. Richardson +18
We explore binary asteroid formation by spin-up and rotational disruption considering the NASA DART mission's encounter with the Didymos-Dimorphos binary, which was the first small…
The Perturbed Full Two-Body Problem: Application to Post-DART Didymos
Alex J. Meyer, Harrison F. Agrusa, Derek C. Richardson +19
With the successful impact of the NASA DART spacecraft in the Didymos-Dimorphos binary asteroid system, we provide an initial analysis of the post-impact perturbed binary asteroid…

Successful Kinetic Impact into an Asteroid for Planetary Defense
R. Terik Daly, Carolyn M. Ernst, Olivier S. Barnouin +98
While no known asteroid poses a threat to Earth for at least the next century, the catalog of near-Earth asteroids is incomplete for objects whose impacts would produce regional de…

Energy Dissipation in Synchronous Binary Asteroids
Alex J. Meyer, Daniel J. Scheeres, Harrison F. Agrusa +5
Synchronous binary asteroids can experience libration about their tidally-locked equilibrium, which will result in energy dissipation. This is an important topic to the Asteroid Im…
