  We explore an accretion origin for Omega Cen by N-body modeling of the
orbital decay and disruption of a Milky-Way dwarf satellite. This work is
focused on studying a particular satellite model that aims to reproduce the
present orbit of Omega Cen, as recently determined from absolute proper
motions. The model satellite is launched from 58 kpc from the Galactic Center,
on a radial, low-inclination orbit. We find that a capture scenario can produce
an Omega Cen-like object with the current low-energy orbit of the cluster. Our
best model is a nucleated galaxy with a Hernquist density profile that has a
mass of 8 10**8 Msun, and a half-mass radius of 1.4 kpc.
