About migration of small solar system bodies and detection of potentially hazardous objects and space debris fragments
Abstract
Nowadays interest is growing in the population of small bodies in the Solar System. It is caused by two basic reasons. First, the asteroid-comet-meteoroid hazard for space vehicles and, in general, for an Earth's civilization has been actively discussed recently. The fundamental task of studying the population of small bodies in the Solar System, their evolution and ways of migration is requisite in this respect. Second, new radiation detectors such as CCD-cameras which were introduced in the observation practice make the observations of small bodies possible. The~research of fireball and meteor streams of bodies of meter and decameter sizes was carried out. The~quantitative estimation of the streams of celestial bodies which are potentially hazardous for the~Earth was made on the basis of a complex meteor-fireball research. Observations near the radiants of meteor and fireball streams allow the detection of potentially hazardous objects of meter and decameter size. The possible existence of Saturn-librated asteroids is discussed. The analysis of asteroid population at the triangle libration points of Saturn as well as of previous observational search is presented. The technique used and previous results of observations are presented.
