A Contact Binary Satellite of the Asteroid (152830) Dinkinesh
Harold F. Levison, Simone Marchi, Keith S. Noll +3
Asteroids with diameters less than about 5 km have complex histories because they are small enough for radiative torques, YORP, to be a notable factor in their evolution. (152830)…
Impact disruption of Bjurböle porous chondritic projectile
Tomas Kohout, Maurizio Pajola, Assi-Johanna Soini +10
The ~200 m/s impact of a single 400-kg Bjurböle L/LL ordinary chondrite meteorite onto sea ice resulted in the catastrophic disruption of the projectile. This resulted in a signifi…

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…
Predicting asteroid material properties from a DART-like kinetic impact
