16. Some Correlation Dependences in Families of Aton and Apollo and Rendezvous Frequency in Main Asteroid Belt

Annotation: The paper presents the a priori probabilities of collision with the Earth for asteroids of Aten and Apollo groups according to Epic and the minimal distances between the orbits of those asteroids and the Earth orbit. The respective regression equations have been derived. For the first thousand of asteroids of the main belt, a number of conclusions are presented concerning genetic relationship between some of them and possibility in principle of close approach (crossing) of their orbits. Some peculiarities are noted of organization and making mass calculations by Halle’s method. The incompleteness of the results obtained is noted.
