Tracing the main belt origins of S-complex near-Earth objects: From space mission targets to meteorite sources
P. N. Simon, P. Vernazza, M. Marsset +5
Context. Space missions to near-Earth objects (NEOs) provide unique opportunities to study and characterise their physical and compositional properties. Interpreting these results…
Probing the Taxonomic Diversity of the Small Near-Earth Object Population
Andy J. López-Oquendo, David E. Trilling, Michael Mommert +1
Small near-Earth objects (NEOs) represent the immediate source population of meteors and meteorites and provide a direct window into the compositional and dynamical evolution of th…
Unmasking (44) Nysa: Evidence for a trilobate structure
Kate Minker, Anthony Berdeu, Gianluca Li Causi +16
Context. (44) Nysa is one of the largest known E-type asteroids. Light curve inversion models have indicated that it may have an elongated shape commonly found in large binary syst…
Dark asteroids exhibiting intermediate characteristics between C and X types
Sunao Hasegawa, Chrysa Avdellidou, Michael Marsset +8
Large main-belt asteroids with visible geometric albedos below 0.1 are predominantly classified within the C- and X-complex spectroscopic classes. C-type and dark X-type asteroids…
The spin state of asteroid Apophis and a prediction of its change during the 2029 close encounter with Earth
J. Durech, D. Vokrouhlicky, P. Pravec +23
On April 13, 2029, the asteroid Apophis will pass near Earth at a geocentric distance of about 38,000 km. Numerical models have suggested that the post-encounter spin state will cr…
Tianwen-2 target asteroid (469219) Kamo'oalewa probably develops an Itokawa-compositional but ultra-highly space-weathered surface
Pengfei Zhang, Guozheng Zhang, Zichen Wei +45
China's Tianwen-2 mission plans to return samples from a small, rapidly spinning Earth quasi-satellite (469219) Kamo'oalewa. Previous studies linked Kamo'oalewa to lunar compositio…
Apophis source population and Earth encounter frequency of Apophis-like bodies
M. Brož, R. P. Binzel, P. Vernazza +4
We provide context for Apophis' 2029 Earth passage by analyzing its possible source populations, in particular, the Flora family, which has a similar composition, corresponding to…
The Nysa family as the main source of unequilibrated LL ordinary chondrites
M. Marsset, P. Vernazza, M. Brož +16
Context. The origin of the petrologic diversity observed in ordinary chondrites (OCs), the most common meteorites on Earth, remains debated. Competing models invoke either depth-de…
Col-OSSOS: Investigating the Origins of Different Surfaces in the Primordial Kuiper Belt
Laura E. Buchanan, Megan E. Schwamb, Wesley C. Fraser +12
The Colours of the Outer Solar System Origins Survey (Col-OSSOS) measured the optical/NIR colours of a brightness-complete sample of Trans-Neptunian Objects (TNOs). Like previous s…
Catastrophic disruption of asteroid 2023 CX1 and implications for planetary defense
Auriane Egal, Denis Vida, François Colas +94
Mitigation of the threat from airbursting asteroids requires an understanding of the potential risk they pose for the ground. How asteroids release their kinetic energy in the atmo…
A dynamical dichotomy in large binary asteroids
K. Minker, B. Carry, F. Vachier +20
No less than 15% of large (diameter greater than 140 km) asteroids have satellites. The commonly accepted mechanism for their formation is post-impact reaccumulation. However, the…
Snapshot of a new interstellar comet: 3I/ATLAS has a red and featureless spectrum
Cyrielle Opitom, Colin Snodgrass, Emmanuel Jehin +19
The interstellar comet 3I/ATLAS is only the third interstellar object to be discovered. Pre-perihelion measurements provide a unique opportunity to study its activity and compositi…
A portrait throughout perihelion of the NH-rich interstellar comet 2I/Borisov
Sophie E. Deam, Michele T. Bannister, Cyrielle Opitom +12
The interstellar comet 2I/Borisov is the first interstellar object where compositional characterisation was possible throughout its entire perihelion passage. We report all 16 epoc…
Size Constraint on Hayabusa2 Extended Mission Rendezvous Target 1998~KY via VLT/VISIR Non-detection
Jin Beniyama, Thomas G. Müller, Marco Delbo +4
1998~KY is a tiny near-Earth asteroid () discovered in 1998. It has been selected as the target of the Hayabusa2 extended mission, which will rendezvous with 1998 KY…
Orbits of very distant asteroid satellites
K. Minker, B. Carry, F. Vachier +36
The very wide binary asteroid (VWBA) population is a small subset of the population of known binary and multiple asteroids made of systems with very widely orbiting satellites and…
Source regions of carbonaceous meteorites and NEOs
M. Brož, P. Vernazza, M. Marsset +15
The present work aims to determine the source regions of carbonaceous chondrites (CM, CI, CO, CV, CK, CR, CH, CB, or C-ungrouped). We studied 38 individual asteroid families, inclu…
The Massalia asteroid family as the origin of ordinary L chondrites
Michaël Marsset, Pierre Vernazza, Miroslav Brož +10
Studies of micrometeorites in mid-Ordovician limestones and Earth's impact craters indicate that our planet witnessed a massive infall of ordinary L chondrite material 466 million…
Young asteroid families as the primary source of meteorites
M. Brož, P. Vernazza, M. Marsset +4
Understanding the origin of bright shooting stars and their meteorite samples is among the most ancient astronomy-related questions that at larger scales has human consequences [1-…
Compositional properties of planet-crossing asteroids from astronomical surveys
A. V. Sergeyev, B. Carry, M. Marsset +8
