More than 6000 asteroids in the Solar System have now been discovered and enumerated, and about 500 of them have been investigated in detail by different methods. This rewiew gives observational evidence which indicates that no fewer than 10% of asteroids may be composed of two or more bodies.

The absence of satellites of asteroids
Icarus, 1987Abstract A CCD-imaging survey was made for satellites of minor planets at distances of about 0.1 to 7 arcmin from 1 Ceres, 2 Pallas, 4 Vesta, 6 Hebe, 7 Iris, 8 Flora, 15 Eunomia, 29 Amphitrite, 41 Daphne, and 44 Nysa, with cursory inspection of 192 Nausikaa. Satellites larger than 3 km were not found in this work, nor in previous photographic surveys.

Satellites of two large asteroids
Astronomical & Astrophysical Transactions, 1998Abstract Various observational data obtained over a period of about 100 years have led to the assumption that some asteroids have satellites. A review of publications has allowed us to compose a list of 50 asteroids that are supposed to be binary. Asteroid 243 Ida with satellite Dactil discovered by space probe Galileo became the 51st.

Orbits of very distant asteroid satellites
Astronomy and 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 widely orbiting 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.

On the fragmentation of asteroids and planetary satellites
Icarus, 1990A general scaling model is defined which allows the extrapolation of small-scale collisional fragmentation experiment results, and existing collisional theories are considered within its framework. Scaling based exclusively upon the specific energy, Q, of the event (the ratio of projectile kinetic energy to the mass of the target body) is shown to hold

Asteroids with satellites: Analysis of observational data
Solar System Research, 2013The volume of observational information on asteroids and trans-Neptunians with satellites has significantly increased in recent years. In this paper we study the dependence of asteroid duplicity on the main physical parameters of the primary: the size and rotation rate.
