Scientific Rationale

The last decades have shown a continuous development in dynamics modelling of celestial bodies at various time scales, from days to periods of time comparable with the age of the Solar system, and length scales, from several kilometers to hundreds of astronomical units. New and more refined models are requested by the enormous amount of highly accurate observational data, collected from ground and space, as well as by the current and future space missions. The range of phenomena that manifest at all different time and length scales and the wide range of sizes of space objects, from minor bodies in the Solar system to exoplanets, from dust particles to Jupiter-size bodies, has required the development of modelling and analysis tools that can handle these different scales. The understanding of the dynamics of these space objects is a key to the advancement of space science and technology, with considerable benefits to society and economy. The emergence of new open problems in space science, such as the formation, habitability and long-term evolution of planetary systems, the complex dynamical behavior of minor bodies in the Solar system, the increased traffic in Earth orbit, the exploration and exploitation of space objects, has stimulated the birth of new lines of investigation, the development of new scientific methods and techniques as well as the development of technologies with a potential big impact on our everyday life.

This Symposium will cover the recent advances in the multi-scale dynamics of natural and artificial space objects from various perspectives: modelling, development of new methods and tools to analyze the dynamics, stability analysis, exploration and exploitation of minor bodies. The Symposium will serve a wide international community working in various fields: physics, celestial mechanics, astrodynamics, planetary sciences, space engineering, applied mathematics, dynamical systems. The Symposium will provide an ideal venue for interdisciplinary discussions, exchanging ideas, making future plans and developing new collaborations.

Key topics

The IAU Symposium will cover the following topics:

  1. Large-scale body dynamics: planets and exoplanets;
  2. Medium-scale body dynamics: asteroids, comets, NEOs, natural satellites;
  3. Small-scale body dynamics: dust particles, rings and space debris;
  4. Perturbation methods and long-term evolution of space objects;
  5. Numerical and analytical methods for resonances and chaos;
  6. Exploration and exploitation of space objects.
