Approximations for Secular Variation Maxima of Classical Orbital Elements under Low Thrust

Mathematics, 2023
The reachability assessment of low-thrust spacecraft is of great significance for orbital transfer, because it can give a priori criteria for the challenging low-thrust trajectory design and optimization.

Calculation Mars – Earth distance and Mars orbital elements with Julian date

Iraqi Journal of Physics, 2023
In this paper, the Mars orbital elements were calculated. These orbital elements—the major axis, the inclination (i), the longitude of the ascending node (W), the argument of the perigee (w), and the eccentricity (e)—are essential to knowing the size ...

Comparative analysis of mathematical models for estimating the impact probability of asteroid Apophis

Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2012
Methods for estimating the impact probability of asteroid Apophis were implemented. The probability of a collision was assessed using two methods: the Monte Carlo method, and the second one, utilizing a ratio between the interval of values of orbital ...

Catalogue of comets passing through perihelion in 2016

Вісник Астрономічної школи, 2015
A catalog of comets that pass the perihelion in 2016 is made. 69 comets will pass through perihelion in 2016: 17 short-period comets will pass the perihelion for the second time and we need a confirmation of these transits, and the 46 “old” short-period ...
