  Radar observations show that (16) Psyche is one of the largest and most
massive asteroids of the M-class located in the main belt, with a diameter of
approximately 230 km. This fact makes Psyche a unique object since observations
indicated an iron-nickel composition. It is believed that this body may be what
was left of a metal core of an early planet that would have been fragmented
over millions of years due to violent collisions. In this work we study a
variety of dynamical aspects related to the surface, as well as, the
environment around this asteroid. We use computational tools to explore the
gravitational field generated by this body, assuming constant values for its
density and rotation period. We then determine a set of physical and dynamical
characteristics over its entire surface. The results include the geometric
altitude, geopotential altitude, tilt, slope, among others. We also explore the
neighborhood around the asteroid (16) Psyche, so that the location and linear
stability of the equilibrium points were found. We found four external
equilibrium points, two of them linearly stable. We confirmed the stability of
these points by performing numerical simulations of massless particles around
the asteroid, which also showed an asymmetry in the size of the stable regions.
In addition, we integrate a cloud of particles in the vicinity of (16) Psyche
in order to verify in which regions of its surface the particles are most
likely to collide.
