Trojan Asteroid Satellites, Rings, and Activity
Space Science Reviews, 2023 The Lucy mission will encounter five Jupiter Trojans during its mission with three of the five already known to be multiple systems. These include a near-equal-mass binary, a small and widely separated satellite, and one intermediate-size satellite ...

Lunar ejecta origin of near-Earth asteroid Kamo'oalewa is compatible with rare orbital pathways. [PDF]
Commun Earth Environ, 2023 Near-Earth asteroid, Kamo’oalewa (469219), is one of a small number of known quasi-satellites of Earth; it transitions between quasi-satellite and horseshoe orbital states on centennial timescales, maintaining this dynamics over megayears. The similarity

Physical, spectral, and dynamical properties of asteroid (107) Camilla and its satellites [PDF]
Icarus, 2018 The population of large 100+ km asteroids is thought to be primordial. As such, they are the most direct witnesses of the early history of our Solar System available.

Celestial Bodies Far-Range Detection with Deep-Space CubeSats. [PDF]
Sensors (Basel), 2023 Detecting celestial bodies while in deep-space travel is a critical task for the correct execution of space missions. Major bodies such as planets are bright and therefore easy to observe, while small bodies can be faint and therefore difficult to ...

The Potential Danger to Satellites due to Ejecta from a 2032 Lunar Impact by Asteroid 2024 YR4
The Astrophysical Journal LettersOn 2032 December 22, the 60 m diameter asteroid 2024 YR _4 has a 4% chance of impacting the Moon. Such an impact would release 6.5 MT TNT equivalent energy and produce a ∼1 km diameter crater.
