Rotation, spectral type, and albedo of the potentially hazardous asteroid (153814) 2001 WN Prior to the 2028 June close approach
Jin Beniyama, Alexey V. Sergeyev, Konstantinos Odysseas Xenos +6
The potentially hazardous asteroid (153814) 2001 WN will pass inside the lunar distance on June 26, 2028, offering a rare opportunity to characterize a kilometer-scale near-Ear…
Refined rotational state and shape model of (98943) Torifune ahead of the Hayabusa2# flyby
P. Fatka, P. Pravec, P. Scheirich +4
The Hayabusa2# mission will perform a high-speed flyby of near-Earth asteroid (98943) Torifune on 5 July 2026, offering a rare opportunity to compare a pre-encounter spin and shape…
Polarimetry and albedo of the Near-Earth Asteroid 2025 FA22
J. -P. Rivet, S. Bagnulo, P. Bendjoya +17
We report spectropolarimetric and broadband polarimetric observations of the near-Earth asteroid 2025 FA22 during its close approach of 18 September 2025 (about two Moon distances)…
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…
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…
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…
