Two Distinct Populations of Dark Comets Delineated by Orbits and Sizes
Darryl Z. Seligman, Davide Farnocchia, Marco Micheli +7
Small bodies are capable of delivering essential prerequisites for the development of life, such as volatiles and organics, to the terrestrial planets. For example, empirical evide…
Tuning the Legacy Survey of Space and Time (LSST) Observing Strategy for Solar System Science: Incremental Templates in Year 1
James E. Robinson, Megan E. Schwamb, R. Lynne Jones +13
The Vera C. Rubin Observatory is due to commence the 10-year Legacy Survey of Space and Time (LSST) at the end of 2025. To detect transient/variable sources and identify solar syst…
Momentum Transfer from the DART Mission Kinetic Impact on Asteroid Dimorphos
Andrew F. Cheng, Harrison F. Agrusa, Brent W. Barbee +66
The NASA Double Asteroid Redirection Test (DART) mission performed a kinetic impact on asteroid Dimorphos, the satellite of the binary asteroid (65803) Didymos, at 23:14 UTC on Sep…
Successful Kinetic Impact into an Asteroid for Planetary Defense
R. Terik Daly, Carolyn M. Ernst, Olivier S. Barnouin +98
While no known asteroid poses a threat to Earth for at least the next century, the catalog of near-Earth asteroids is incomplete for objects whose impacts would produce regional de…
Orbital Period Change of Dimorphos Due to the DART Kinetic Impact
Cristina A. Thomas, Shantanu P. Naidu, Peter Scheirich +46
The Double Asteroid Redirection Test (DART) spacecraft successfully performed the first test of a kinetic impactor for asteroid deflection by impacting Dimorphos, the secondary of…
Spin State Evolution of (99942) Apophis during its 2029 Earth Encounter
C. J. Benson, D. J. Scheeres, M. Brozovic +3
We explore the effects of the 2029 Earth encounter on asteroid (99942) Apophis' non-principal axis spin state, leveraging refined orbit, spin state, and inertia information provide…
OSIRIS-REx: Sample Return from Asteroid (101955) Bennu
D. S. Lauretta, S. S. Balram-Knutson, E. Beshore +45
In May of 2011, NASA selected the Origins, Spectral Interpretation, Resource Identification, and Security-Regolith Explorer (OSIRIS-REx) asteroid sample return mission as the third…
High precision comet trajectory estimates: the Mars flyby of C/2013 A1 (Siding Spring)
D. Farnocchia, S. R. Chesley, M. Micheli +6
The Mars flyby of C/2013 A1 (Siding Spring) represented a unique opportunity for imaging a long-period comet and resolving its nucleus and rotation period. Because of the small enc…
The Yarkovsky and YORP Effects
D. Vokrouhlicky, W. F. Bottke, S. R. Chesley +2
The Yarkovsky effect describes a small but significant force that affects the orbital motion of meteoroids and asteroids smaller than kilometers in diameter. It is caused b…
Assessment of the 2880 impact threat from asteroid (29075) 1950 DA
D. Farnocchia, S. R. Chesley
In this paper we perform an assessment of the 2880 Earth impact risk for asteroid (29075) 1950 DA. To obtain reliable predictions we analyze the contribution of the observational d…
Detection of Semi-Major Axis Drifts in 54 Near-Earth Asteroids: New Measurements of the Yarkovsky Effect
C. R. Nugent, J. L. Margot, S. R. Chesley +1
We have identified and quantified semi-major axis drifts in Near-Earth Asteroids (NEAs) by performing orbital fits to optical and radar astrometry of all numbered NEAs. We focus on…
