Optical Characterization of the DART Impact Plume: Importance of Realistic Ejecta Scattering Properties

open access: yesThe Planetary Science Journal, 2023
The Double Asteroid Redirection Test (DART) mission will impact the moon Dimorphos of the (65803) Didymos binary and demonstrate the kinetic impactor technique for planetary defense.

Significantly high polarization degree of the very low-albedo asteroid (152679) 1998 KU2 [PDF]

open access: yes, 2017
We present a unique and significant polarimetric result regarding the near-Earth asteroid (152679) 1998 KU 2 , which has a very low geometric albedo. From our observations, we find that the linear polarization degrees of 1998 KU 2 are 44.6 ± 0.5% in the ...

An Earth Encounter as the Cause of Chaotic Dynamics in Binary Asteroid (35107) 1991VH

open access: yesThe Planetary Science Journal
Among binary asteroids, (35107) 1991VH stands out as unique given the likely chaotic rotation within its secondary component. The source of this excited dynamical state is unknown. In this work, we demonstrate that a past close encounter with Earth could

An Updated Shape Model of Dimorphos from DART Data

open access: yesThe Planetary Science Journal
Dimorphos was the target of the Double Asteroid Redirection Test (DART) mission. This paper summarizes the properties of an updated shape model of Dimorphos, describes the differences between the updated shape model and an earlier version published by ...

Temporal Earth Coorbital Types of Asteroid 2016 HO3

open access: yesJournal of Physics: Conference Series, 2019
A newly discovered asteroid 2016 HO3 has coorbital type of retrograde (or quasi) satellite with respect to Earth. The discovery enlarges number of known retrograde satellites of Earth.

Fully Coherent Model of Dynamics around Binary Asteroids: Application to Didymos and the DART Impact

open access: yesThe Planetary Science Journal
The dynamical environment around binary asteroids has been studied in depth, but these models typically make assumptions about the eccentricity, shapes, or rotational stability of the asteroids.

Orbit of the Patroclus–Menoetius Binary System and Predictions for the 2024/2025 Mutual Events Season

open access: yesThe Astronomical Journal
We report on the ephemeris development for Menoetius, the satellite of Patroclus. Our data set consisted of ground–based and Hubble Space Telescope relative astrometry, as well as 42 lightcurves from the mutual events seasons in 2007, 2012, and 2017/2018.

Tour of Asteroids for Characterization Observations (TACO): A Planetary Defense Asteroid Tour Concept

open access: yesThe Planetary Science Journal
Asteroid impacts potentially represent a substantial threat to humanity, but one that we can plan for and mitigate. To design an effective asteroid mitigation mission, however, it is important to have as detailed knowledge of the asteroid threat as ...

Dimorphos’s Orbit Period Change and Attitude Perturbation due to Its Reshaping after the DART Impact

open access: yesThe Planetary Science Journal
On 2022 September 26 (UTC), NASA's Double Asteroid Redirection Test (DART) mission achieved a successful impact on Dimorphos, the secondary component of the near-Earth binary asteroid system (65803) Didymos. Subsequent ground-based observations suggest a
