Size Constraints for the Pre-atmospheric Parent Bodies of Ordinary Chondrites
Juan A. Sanchez, David C. Cantillo, Adam Battle +7
The study of S-complex near-Earth objects (NEOs), the parent bodies of ordinary chondrites, has shown that they are dominated by asteroids with LL chondrite-like compositions. This…
Analysis of Karin and Koronis2 asteroid families: new findings and challenges
David Vokrouhlický, David Nesvorný, William F. Bottke
We use our home catalog of the asteroid proper elements to study the Karin family. The hierarchical clustering method provides formal identification with 3,863 members, but this se…
Terrestrial Planet Formation from Two Source Reservoirs
David Nesvorny, Alessandro Morbidelli, William F. Bottke +2
This work describes new dynamical simulations of terrestrial planet formation. The simulations started at the protoplanetary disk stage, when planetesimals formed and accreted into…
Size-Frequency Distribution of Terrestrial Leftover Planetesimals and S-complex Implanted Asteroids
Rogerio Deienno, Andre Izidoro, David Nesvorny +3
The isotopic composition of meteorites linked to S-complex asteroids has been used to suggest that these asteroids originated in the terrestrial planet's region, i.e., within 1.5 a…
A pre-flyby view on the origin of asteroid Donaldjohanson, a target of the NASA Lucy mission
Simone Marchi, David Vokrouhlický, David Nesvorný +3
The NASA Lucy mission is scheduled to fly-by the main belt asteroid (52246) Donaldjohanson on April 20, 2025. Donaldjohanson (DJ hereafter) is a member of the primitive (C-type cla…
Orbital and absolute magnitude distribution of Hilda population
David Vokrouhlický, David Nesvorný, Miroslav Brož +4
The Hilda population of asteroids is located in a large orbital zone of long-term stability associated with the Jupiter J3/2 mean motion resonance. They are a sister population of…
