In the era of practical space exploration, a sufficient amount of artificial objects remnants has
accumulated in near-Earth space, ground control of which is lost. So, the important applied …

In 1961, Kordylewski found two bright patches near the L5 Lagrange point of the Earth–
Moon system. This referred to an accumulation of dust particles, later called as Kordylewski …

Abstract In 1961, the Polish astronomer, Kazimierz Kordylewski found dust clouds around
the triangular Lagrange points L4 and L5 of the Earth-Moon system. After this discovery …

The stability of spatial orbits around the triangular libration points in the ephemeris model of
the Earth–Moon system is studied. Five contributions are made:(1) practical stable spatial …

The solar radiation pressure is one of the major perturbations to orbits in the study of binary
asteroid system, since asteroids have relatively weak gravity fields. In this paper, based on …

Important applied aspects of the numerous scientific problems are the issues of safety of
space missions. Among such investigations are the following: ensuring the safety of flights …

ABSTRACT The Kordylewski dust clouds (KDCs) around the L5 and L4 Lagrange points of
the Earth–Moon system have been first observed by imaging polarimetry in 2017 and 2022 …

Detection of areas of increased density of cosmic dust in near-Earth space is important from
both theoretical and practical points of view. To continue our explication of the phenomenon …

Practical space exploration has a priority the issues of safety of space missions. And an
important fundamental problem arises—the study of the evolution and the stability of a space …

In this chapter, we deal with the following astropolarization studies: Sky-polarimetric
corroboration of the resolution of the UV-sky-pol paradox of insect celestial polarization …
