The Dynamical State of the Didymos System Before and After the DART Impact
Derek C. Richardson, Harrison F. Agrusa, Brent Barbee +50
NASA's Double Asteroid Redirection Test (DART) spacecraft impacted Dimorphos, the natural satellite of (65803) Didymos, on 2022 September 26, as a first successful test of kinetic…
Internal rubble properties of asteroid (101955) Bennu
P. Tricarico, D. J. Scheeres, A. S. French +24
Exploration of asteroid (101955) Bennu by the OSIRIS-REx mission has provided an in-depth look at this rubble-pile near-Earth asteroid. In particular, the measured gravity field an…
Spitzer Observations of Interstellar Object 1I/`Oumuamua
DE Trilling, M Mommert, JL Hora +20
1I/`Oumuamua is the first confirmed interstellar body in our Solar System. Here we report on observations of `Oumuamua made with the Spitzer Space Telescope on 2017 November 21--22…
Systematic ranging and late warning asteroid impacts
D. Farnocchia, S. R. Chesley, M. Micheli
We describe systematic ranging, an orbit determination technique especially suitable to assess the near-term Earth impact hazard posed by newly discovered asteroids. For these late…
Non-gravitational Perturbations and Virtual Impactors: the case of asteroid 2009 FD
F. Spoto, A. Milani, D. Farnocchia +5
Asteroid 2009 FD could impact Earth between 2185 and 2196. The long term propagation to the possible impacts and the intervening planetary encounters make 2009 FD one of the most c…
Yarkovsky-driven impact risk analysis for asteroid (99942) Apophis
D. Farnocchia, S. R. Chesley, P. W. Chodas +5
We assess the risk of an Earth impact for asteroid (99942) Apophis by means of a statistical analysis accounting for the uncertainty of both the orbital solution and the Yarkovsky…
