Multiple sources of evidence suggest that asteroids ranging from hundreds meters to few
kilometers in size are rubble piles, ie gravitational aggregates of loosely consolidated …

Phobos is one of the two moons of Mars, the only other terrestrial planet to have
companions. In spite of certain common orbital characteristics between Earth's Moon and …

We propose an approach to infer large-scale heterogeneities within a small celestial body
from measurements of its gravitational potential, provided for instance by spacecraft radio …

The origin of the Martian moons is still uncertain, and knowledge about their interior could
provide support to some of its leading theories. In preparation for the JAXA Martian Moons …

Observations of near-Earth asteroid Bennu have revealed a dynamic surface composed of
unconsolidated material. The OSIRIS-REx (Origins, Spectral Interpretation, Resource …

An analytical gravity modeling formulation for heterogeneous bodies is developed in this
paper, in which the compact closed formulation of gravitational potential and attraction is …
