The operational environment and rotational acceleration of asteroid (101955) Bennu from OSIRIS-REx observations

The authors show the operational environment of asteroid Bennu, validate its photometric phase function and demonstrate the accelerating rotational rate due to YORP effect using the data acquired during the approach phase of OSIRIS-REx mission.

Unique Light Scattering at Occator's Faculae on (1) Ceres

The Occator crater on the dwarf planet Ceres is outstanding because of its relatively low age (∼22 Ma) and extremely young (≤4 Ma) and bright faculae on an otherwise mostly dark body (ratio of

Photometry of Particles Ejected From Active Asteroid (101955) Bennu

Near‐Earth asteroid (101955) Bennu is an active asteroid experiencing mass loss in the form of ejection events emitting up to hundreds of millimeter‐ to centimeter‐scale particles. The close

Introduction to the Special Issue: Exploration of the Activity of Asteroid (101955) Bennu

Of the potential mechanisms behind this activity that were investigated in focused studies, meteoroid impacts, thermal fracturing, and ricochet—but not water ice sublimation—were found to be consistent with observations, suggesting that many near‐Earth asteroids may exhibit activity that has gone unnoticed thus far.

Dawn Spacecraft Performance: Resource Utilization and Environmental Effects During an 11-Year Mission

Dawn was a deep space science mission to the asteroid belt, using solar electric propulsion and a spacecraft derived from an earth-orbiting communications satellite. Although much of the operationa...

A SEARCH FOR SATELLITES AROUND CERES

We conducted a satellite search around the dwarf planet 1 Ceres using Hubble Space Telescope and ground-based Palomar data. No candidate objects were found orbiting Ceres in its entire stability

Asteroids with Satellites: Inventory, Properties, and Prospects for Future Discoveries

The population of binary asteroids numbers over 160 systems, and they can be found amongst near-Earth asteroids (NEAs), Main-Belt asteroids (MBAs), Jupiter Trojans, Centaurs and trans-Neptunian

NEAR Encounter with Asteroid 253 Mathilde: Overview

Abstract On June 27, 1997, the NEAR spacecraft carried out the first-ever encounter with a C-type asteroid, flying by 253 Mathilde at a distance of 1212 km. We summarize findings derived from 330

Discovery of a moon orbiting the asteroid 45 Eugenia

Evidence for asteroidal satellites (moons) has been sought for decades, because the relative frequency of such satellites will bear on the collisional history of the asteroid belt and the Solar

Dawn at Vesta: Testing the Protoplanetary Paradigm

Dawn's results confirm predictions that Vesta differentiated and support its identification as the parent body of the HEDs, and present the mineralogical characterization of Vesta, revealing that this asteroid underwent a complex magmatic evolution that led to a differentiated crust and mantle.

A Search for Satellites and Dust Belts Around Asteroids: Negative Results

In spite of several dedicated optical searches (1-4), the existence of binary asteroids, asteroidal satellite swarms, or asteroidal dust clouds suggested by asteroid-star occultation events (5) has
