Abstract We present simulation results on evolution development of orbital motion of short-period comets with the revolution period not exceeding 6–7 years, namely comets 21P/Giacobini–Zinner, 26P/Grigg– Skjellerup and 7P/Pons–Winnecke. The calculations cover the range from the date of the object’s discovery to 2100. Variations in the objects’ orbital elements under the action of gravity disturbances, taking Earth’s gravitational potential into account when the small body approaches, are analyzed. Corrected dates of perihelion passages can be used for scheduling observations.
Keywords comets: individual (21P/Giacobini–Zinner, 26P/Grigg–Skjellerup, 7P/Pons–Winnecke) — me- teorites, meteors, meteoroids
