The paper presents the results of investigation of the dynamical behaviour of small solar system objects with model orbits similar to SOHO comets, assuming their orbits to be near parabolic. The numerical integration of the equation of motion of the objects showed that the bodies periodically change their inclination, eccentricities, and perihelion distances within a rather wide range. During this time, they can reach the vicinity of both the outer planets and the Sun and cross the Earth orbits. The obtained results were compared to the motion of high inclination asteroids. The bodies of both populations show similar dynamical behaviour with a common characteristic, the migration within the solar system.
