Satellite Formation around the Largest Asteroids
The Astrophysical Journal LettersAbstract Satellites around large asteroids are preferentially found among those with the most rapid rotation and elongated shape. The taxonomic statistics are similarly skewed; in total, 13 asteroids larger than 100 km are known to have satellites, but none have been discovered among S-type asteroids.

A contact binary satellite of the asteroid (152830) Dinkinesh [PDF]
NatureAbstract Asteroids with diameters less than about 5 km have complex histories because they are small enough for radiative torques (that is, YORP, short for the Yarkovsky–O’Keefe–Radzievskii–Paddack effect) 1 to be a notable factor in their evolution 2

On the stability of the satellites of asteroid 87 Sylvia [PDF]
Monthly Notices of the Royal Astronomical Society, 2009 he triple asteroidal system (87) Sylvia is composed of a 280-km primary and two small moonlets named Romulus and Remus (Marchis et al 2005). Sylvia is located in the main asteroid belt. The satellites are in nearly equatorial circular orbits around the primary.

Trojan Asteroid Satellites, Rings, and Activity
Space Science Reviews, 2023 AbstractThe 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 system.

Orbits of very distant asteroid satellites
Astronomy & AstrophysicsThe very wide binary asteroid (VWBA) population is a small subset of the population of known binary and multiple asteroids made of systems with very distant satellites and long orbital periods, on the order of tens to hundreds of days. The origin of these systems is debatable, and most members of this population are poorly characterized.

Inflatable Dome for Moon, Mars, Asteroids, and Satellites
AIAA SPACE 2007 Conference & Exposition, 2007 On a planet without atmosphere, sustaining human life is very difficult and dangerous, especially during short sunlit period when low temperature prevails. To counter these environmental stresses, the author offer an innovative artificial "Evergreen" dome, an inflated hemisphere with interiors continuously providing a climate like that of Florida ...

Asteroid Satellite Discovery Optimization
The discovery of asteroid-satellite systems not only reveals the formation and evolution mechanisms of small solar system bodies but also provides insights into the optimization of complex systems. This paper proposes a heuristic optimization algorithm based on the principles of asteroid-satellite discovery.

Asteroid Satellite Inspired Optimization
Asteroid satellite systems, as important binary or multi-body structures in the solar system, are of great significance to the study of astrophysics and orbital mechanics. This paper proposes a heuristic optimization algorithm based on the asteroid satellite discovery process—the Asteroid Satellite Inspired Optimization (ASIO) algorithm. This algorithm

Asteroid-Satellite Perturbation Optimization
Asteroid-Satellite Perturbation Optimization (ASP-O) is a complex nonlinear dynamical problem, characterized by gravitational interactions between the primary asteroid and its satellite, as well as orbital variations caused by external perturbations.
