In this work, we performed a dynamical analysis of a spacecraft around a nearly equal-mass binary near-Earth asteroid with application to the asteroid 2017 YE5, which is also a pos…
Machine learning to predict the solar flux and geomagnetic indices to model density and Drag in Satellites
S. Aljbaae, J. Murcia-Pineros, A. F. B. A. Prado +3
In recent years (2000-2021), human-space activities have been increasing faster than ever. More than 36000 Earth' orbiting objects, all larger than 10 cm, in orbit around the Earth…
Optimization of Artificial Neural Networks models applied to the identification of images of asteroids' resonant arguments
Valerio Carruba, Safwan Aljbaae, Gabriel Caritá +2
The asteroidal main belt is crossed by a web of mean-motion and secular resonances, that occur when there is a commensurability between fundamental frequencies of the asteroids and…
