Abstract
The orbital evolution of model meteoroids ejected from the comet Encke has been investigated. Tile particles abandon the mother body with ve locities 20 and 40 ms(-1) at its perihelion within the interval of the past 10,000 years. Their 10,000 years old osculating orbits were nume rically integrated forward, using a dynamical model of the solar syste m consisting of all planets. Forces from solar electromagnetic and cor puscular radiation effecting the particles are considered, too. Orbita l dispersions of the model meteoroids are presented. The importance of nongravitational forces for a long-term orbital evolution of meteoroi d streams is shown.
