Dynamics and Coastal Effects of Tsunamis Generated by Asteroids Impacting the Black Sea

Pure and Applied Geophysics, 2010
Two-dimensional (2D) and one-dimensional (1D) shallow-water models are used to evaluate the seashore effects of the tsunami generated by an asteroid impacting the western regions of the Black Sea about 208 km from the coast. The tsunami’s speed and the effects on the coastal regions depend on many factors, among which the most important is asteroid ...

Fast Generation of Optimal Asteroid Landing Trajectories Using Deep Neural Networks

IEEE Transactions on Aerospace and Electronic Systems, 2020
To improve the autonomy and reliability of asteroid landings, an intelligent approach to fast and reliable generation of optimal landing trajectories is proposed. Unfortunately, the indirect methods require good initial guesses for shootings. To address this issue, deep neural networks (DNNs) are developed to approximate the costates of the indirect ...

Orbit Mechanics About Asteroids and Comets

, 2012
Space missions to small solar system bodies such as asteroids and comets must deal with multiple perturbations acting on the spacecraft. These include strongperturbations from the gravityfield and solar tide, but for small bodies, the most important ...

Quasi-satellite orbits in the general context of dynamics in the 1:1 mean motion resonance: perturbative treatment

, 2014
Our investigation is motivated by the recent discovery of asteroids orbiting the Sun and simultaneously staying near one of the Solar System planets for a long time.

Asteroid long-periodic perturbations: generic term representation of the determining function

Planetary and Space Science, 1994
Abstract A simple scheme is introduced for representing, in a computer readable form, the determining function of the canonical transformation needed to compute the asteroid long-periodic perturbations. The theory and the procedures involved in this computation are described in detail.

Generalized restricted circular three-body problem as a model for dynamics of binary asteroids

Cosmic Research, 2007
Exploration of the Solar System has recently revealed the existence of a large number of asteroids with satellites, which has stimulated interest in studying the dynamics of such systems. This paper is dedicated to the analysis of the relative motion of a binary asteroid.
