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…
Mare versus highland lunar impact flash light curve dichotomy
D. Athanasopoulos, A. Liakos, A. Z. Bonanos +5
We perform a comprehensive analysis of lunar impact flash (LIF) light curve shapes and their dependence on the lunar terrain, using the large sample of LIFs detected by NELIOTA ove…
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…
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…
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…
Debiasing astro-Photometric Observations with Corrections Using Statistics (DePhOCUS)
Tobias Hoffmann, Marco Micheli, Juan Luis Cano +5
Photometric measurements allow the determination of an asteroid's absolute magnitude, which often represents the sole means to infer its size. Photometric observations can be obtai…
Aperture photometry on asteroid trails: detection of the fastest rotating near-Earth object
Maxime Devogèle, Luca Buzzi, Marco Micheli +9
Context. Near-Earth objects (NEOs) on an impact course with Earth can move at high angular speed. Understanding their properties, including rotation state, is crucial for assessing…
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…
