Database of astrometric observations of the binary asteroids

521.1:523.4Abstract
A database of astrometric observations of binary asteroids has been created. It organically complements the special database of all the world's observations of natural satellites of the planets, which has been operating for more than 10 years in the Sternberg Astronomical Institute (SAI), Moscow, Russia. The Natural Satellites Service (SAI) is available to all users on the Internet and allows solving a lot of astrometric and celestial-mechanical problems based on observations of satellites. Observations of asteroids can be used to determine the dynamic parameters of the system, the mass of the components, the shape and oblateness of the main body. In addition, it becomes possible to predict the season of mutual phenomena in the system and the occultation of stars. Some asteroids are triplets, and their observations make it possible to determine the diameters of all three components, their density and porosity, the position of the orbit pole, and other parameters of the system.
