Neptune's migration is not fully understood, and has been the subject of a number of numerical n-body simulations. Here, I present another such simulation which attempts to model the migration of a Neptune-like object and other small-bodies in a proto-planetary disk. A FORTRAN 90 code was developed to simulate a simplified proto-solar system, and analyze its evolution over time when a planet with a mass-to-mass ratio similar to that of Neptune and the Sun is introduced into the system. Snapshots of the system are taken on a regular and frequent basis, changes in the distance between Neptune and the central star are recorded, and the orbital parameters of Neptune and other particles are analyzed as a function of time. Immersed in a disk of particles, Neptune's trajectory immediately showed a deviation from its initial near-circular orbit, and a subsequent migration, together with an evolution in the shape of the disk itself.
