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…
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…
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…
An automated procedure for the detection of the Yarkovsky effect and results from the ESA NEO Coordination Centre
Marco Fenucci, Marco Micheli, Francesco Gianotto +7
Context: The measurement of the Yarkovsky effect on near-Earth asteroids (NEAs) is common practice in orbit determination today, and the number of detections will increase with the…
Elimination of a virtual impactor of 2006 QV89 via deep non-detection
Olivier R. Hainaut, Marco Micheli, Juan Luis Cano +3
As a consequence of the large (and growing) number of near-Earth objects discovered, some of them are lost before their orbit can be firmly established to ensure long-term recovery…
Detecting the Yarkovsky effect among near-Earth asteroids from astrometric data
Alessio Del Vigna, Laura Faggioli, Andrea Milani +3
We present an updated set of near-Earth asteroids with a Yarkovsky-related semimajor axis drift detected from the orbital fit to the astrometry. We find 87 reliable detections afte…
