Statistical Properties of Encounters among Asteroids: A New, General Purpose, Formalism
Icarus, 1998Abstract The statistical properties of asteroid mutual encounters have been studied by several authors, with the main purpose of estimating collisional rates (and thus mean collisional lifetimes) and the distribution of encounter velocities. In this paper we present a new approach, conceptually not really different with respect to the classical ones,

Fast Generation of Optimal Asteroid Landing Trajectories Using Deep Neural Networks
IEEE Transactions on Aerospace and Electronic Systems, 2020To 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 ...

Generalized Calibration of the Polarimetric Albedo Scale of Asteroids
Solar System Research, 2018Six different calibrations of the polarimetric albedo scale of asteroids have been published so far. Each of them contains its particular random and systematic errors and yields its values of geometric albedo. On the one hand, this complicates their analysis and comparison; on the other hand, it becomes more and more difficult to decide which of the ...

Dynamics and Coastal Effects of Tsunamis Generated by Asteroids Impacting the Black Sea
Pure and Applied Geophysics, 2010Two-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 ...

Asteroid long-periodic perturbations: generic term representation of the determining function
Planetary and Space Science, 1994Abstract 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.
