From orbit to ground: pre-impact meteorite strewn field predictions for imminent impactors and meteorite recovery
Anna Moscati, Marco Fenucci, Laura Faggioli +3
The flux of meteoroids reaching the Earth is continuous, ranging from microscopic grains to occasional metre and decametre scale bodies. The smallest ones fully ablate in the upper…
Best practices for obtaining astrometric observations from JWST (274) NIRCam data
Marco Micheli, Bryan J. Holler
The James Webb Space Telescope (JWST), with its near-infrared imager NIRCam, is capable of obtaining detections of small bodies down to what would correspond to a visual magnitude…
Machine Learning Assisted NEO Discovery and Polarimetric Characterisation with Astronomical Surveys
G. A. Verdoes Kleijn, T. Grobler, S. J. Chong +12
We are a group of over two dozen astronomers, computer scientists, data scientists and digital Big Data research platform experts at 11 universities and research institutes in Sout…
Astrometric follow-up of near-Earth asteroid 2024 YR4 during a Torino scale level 3 alert
Marco Micheli, Maxime Devogèle, Larry Denneau +38
The discovery of 2024 YR4 presented the planetary defense community with the most significant impact threat in almost two decades, reaching level 3 on the Torino scale. The communi…
The ESA Meerkat Asteroid Guard: a monitoring service for imminent impactors
Charlie Drury, Francesco Gianotto, Marco Fenucci +9
We present the Meerkat Asteroid Guard, an imminent impactor warning service developed and maintained by the European Space Agency's Near-Earth Object Coordination Centre (NEOCC). T…
Investigation of the dynamics and origin of the NEA pair 2021 PH27 and 2025 GN1
Albino Carbognani, Marco Fenucci, Toni Santana-Ros +2
We analyse the association between the NEAs 2021 PH27 and 2025 GN1, which share similar heliocentric Keplerian elements and the same taxonomic classification. First, we confirm the…
Rapid-response characterization of near-Earth asteroid 2024 YR4 during a Torino Scale 3 alert
Maxime Devogèle, Olivier R. Hainaut, Marco Micheli +32
On 27 December 2024, near-Earth object (NEO) 2024 YR was discovered by the ATLAS survey and identified as a virtual impactor. A few weeks later, it eventually reached level 3 o…
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…
Discovery and Preliminary Characterization of a Third Interstellar Object: 3I/ATLAS
Darryl Z. Seligman, Marco Micheli, Davide Farnocchia +44
We report initial observations aimed at the characterization of a third interstellar object. This object, 3I/ATLAS or C/2025 N1 (ATLAS), was discovered on 2025 July 1 UT and has an…
Astrometry, orbit determination, and thermal inertia of the Tianwen-2 target asteroid (469219) Kamo`oalewa
Marco Fenucci, Bojan Novaković, Pengfei Zhang +9
Context. (469219) Kamo`oalewa is a small near-Earth asteroid, which is currently a quasi-satellite of the Earth. Lightcurve measurements also reveal a rotation period of only about…
The fall of asteroid 2024 XA and the location of possible meteorites
Francesco Gianotto, Albino Carbognani, Marco Fenucci +18
Asteroid 2024 XA was discovered on 3 December 2024 at 05:54 UTC by the Bok telescope in Kitt Peak, Arizona, and impacted Earth about 10 hours later over a remote area of the Sa…
Ab initio strewn field for small asteroids impacts
Albino Carbognani, Marco Fenucci, Raffaele Salerno +1
In recent years, nine small near-Earth asteroids were discovered a few hours before the collision with the Earth: these are about one meter in diameter objects that have all disint…
Extremely young asteroid pair (458271) 2010 UM26 and 2010 RN221
D. Vokrouhlický, P. Fatka. M. Micheli, P. Pravec +1
Extremely similar heliocentric orbital elements of the main-belt objects (458271) 2010 UM26 and 2010 RN221 make them the tightest known pair and promise its very young age. We anal…
