Activity of comets and orbit-activity relation

Comets are spectacular celestial objects that are of interest to many disciplines such as astronomy and astrophysics, biology, archeology and geology. They are one of the small bodies of our solar system, which are made of frozen gasses and interplanetary dust particles. Orbits of comets are influenced by Sun and other massive bodies in the solar system, and their activities change due solar energy.. In this thesis, it is reviewed activity, trajectories and dynamical taxonomy of the comets have been studied. Information such as trajectory parameters and gas-dust production ratios have been gathered for 509 comet observation and matched with the data provided by the NASA JPL system. Then, these data have been examined by using graphical methods and plausible relations have been investigated. The results have been compared with previous studies.
