Asteroid Day introduction

This year the Asteroid Day will be performed for the first time at our Department of Astrophysics (Sternwarte) starting at 5 pm in the Hoersaal room and finishing at 10:30 pm. Our experts on asteroids will share their knowledge on this topic, giving different talks (mostly in German, but also in English) about the physical characteristics, observations, and the dynamics of these bodies.
The event will start with a presentation explaining the background of our department in this field of study, giving a historical overview on Johann Palisa, who was one of the most prolific discoverers of asteroids in Austria. Following this we will discuss about the dynamics of the different asteroid groups, which were also studied in Vienna since 1984 by the Astrodynamic Group (ADG) founded by Prof. Dvorak. Then we will cover the nearest asteroids, the Near-Earth Objects (NEOs), which are Earth-orbit crossers and can even collide with our planet. On the other hand we will also discuss the most distant ones, the Trans-Neptunian Objects (TNOs). The TNOs are asteroids beyond Neptune, which are the progenitors of some NEOs. These talks will also introduce impact simulations, observations of asteroids, and future space missions to them (like asteroid mining).
