An accuracy estimation of CCD asteroid observations contained in the Minor Planet Center Database and carried out in the years 1999 - 2006 is realized. About 20 millions individual positions of the Numbered and Unnumbered Minor Planets were tested by means of calculations of (O-C) residuals to derive "mean error of a single observation" for more than 400

До конца XIX века об астероидах сложилось представление как об одиночных телах. ... Расстояние между КА и Гаспрой в момент сближения составило 16000 км и это позволило детально сфотографировать поверхность астероида, размеры которого составляют около 15 км. В конце августа 1993 г. "Галилео" пролетел на расстоянии 11000 км от астероида 243 Ида. ... Матильда имеет размеры 50x50x70 км и является крайне медленно вращающимся астероидом - один оборот за 17.5 суток. ...
