Kometendynamica

Kometendynamica refers to the study of the motion and evolution of comets within the solar system. This field draws upon principles of celestial mechanics, gravity, and the physical properties of comets themselves. Comets are icy bodies that originate in the outer solar system, primarily from the Kuiper Belt and the Oort Cloud. Their orbits are often highly elliptical, meaning they travel far out into space and then swing back in towards the Sun.

When a comet approaches the Sun, the solar radiation causes its volatile ices to sublimate, forming a coma and often a tail. These outgassing processes are not uniform and can lead to changes in the comet's trajectory, a phenomenon known as non-gravitational forces. These forces are a key aspect of kometendynamica, as they can significantly alter a comet's orbit over time, sometimes ejecting it from the inner solar system or even sending it on a collision course with a planet.

The study of kometendynamica involves tracking cometary orbits, modeling their sublimation processes, and understanding how gravitational interactions with planets influence their paths. This research helps us predict future cometary appearances, understand the distribution of comets in the solar system, and shed light on the early history of the solar system from which comets are believed to have originated. It also plays a role in assessing potential impact hazards from near-Earth comets.
