Geodesy of irregular small bodies via neural density fields

Izzo, Dario; Gómez, Pablo

Asteroids' and comets' geodesy is a challenging yet important task for planetary science and spacecraft operations, such as ESA's Hera mission tasked to look at the aftermath of the recent NASA DART spacecraft's impact on Dimorphos. Here we present a machine learning approach based on so-called geodesyNets which learns accurate density models of i…
