Dark asteroids exhibiting intermediate characteristics between C and X types
Sunao Hasegawa, Chrysa Avdellidou, Michael Marsset +8
Large main-belt asteroids with visible geometric albedos below 0.1 are predominantly classified within the C- and X-complex spectroscopic classes. C-type and dark X-type asteroids…
Isotopic Evidence for a Cold and Distant Origin of the Interstellar Object 3I/ATLAS
Martin Cordiner, Nathan X. Roth, Marco Micheli +16
Interstellar objects provide the only directly observable samples of icy planetesimals formed around other stars, and can therefore provide insight into the diversity of physical a…
Multi-wavelength JWST observations of (3200) Phaethon show a dehydrated object with an aqueously altered origin
Cristina A. Thomas, Andrew S. Rivkin, Ian Wong +10
We present JWST observations of the near-Earth asteroid (3200) Phaethon using the Near-Infrared Camera (NIRCam), Near-Infrared Spectrograph (NIRSpec), and Mid-Infrared Instrument (…
Dimorphos orbit determination from mutual events photometry
Peter Scheirich, Petr Pravec, Alex J. Meyer +6
The NASA Double Asteroid Redirection Test (DART) spacecraft successfully impacted the Didymos-Dimorphos binary asteroid system on 2022 September 26 UTC. We provide an update to its…
Photometry of the Didymos system across the DART impact apparition
Nicholas Moskovitz, Cristina Thomas, Petr Pravec +78
On 26 September 2022, the Double Asteroid Redirection Test (DART) spacecraft impacted Dimorphos, the satellite of binary near-Earth asteroid (65803) Didymos. This demonstrated the…
Near-IR Spectral Observations of the Didymos System -- Daily Evolution Before and After the DART Impact, Indicates Dimorphos Originated from Didymos
David Polishook, Francesca E. DeMeo, Brian J. Burt +4
Ejecta from Dimorphos following the DART mission impact, significantly increased the brightness of the Didymos-Dimorphos system, allowing us to examine sub-surface material. We rep…
Ejecta Evolution Following a Planned Impact into an Asteroid: The First Five Weeks
Theodore Kareta, Cristina Thomas, Jian-Yang Li +85
The impact of the DART spacecraft into Dimorphos, moon of the asteroid Didymos, changed Dimorphos' orbit substantially, largely from the ejection of material. We present results fr…
Near to Mid-Infrared Spectroscopy of (65803) Didymos as observed by JWST: Characterization Observations Supporting the Double Asteroid Redirection Test
Andrew S. Rivkin, Cristina A. Thomas, Ian Wong +17
The Didymos binary asteroid was the target of the Double Asteroid Redirection Test (DART) mission, which intentionally impacted Dimorphos, the smaller member of the binary system.…
Compositional distributions and evolutionary processes for the near-Earth object population: Results from the MIT-Hawaii Near-Earth Object Spectroscopic Survey (MITHNEOS
Binzel R. P., DeMeo F. E., Turtelboom E. V. +19
We report measured spectral properties for more than 1000 NEOs, representing>5% of the currently discovered population. Thermal flux detected below 2.5 μm allows us to make albedo…
