The SOLEX page        What is SOLEX ?

Basically, SOLEX is a free computer program modelling the N-body dynamics of the Solar System, and it is the result of a long and patient amatorial work by the author (Aldo Vitagliano).
Its heart is a powerful numerical integrator, and the many additional functions make it a greatly flexible program, which at the same time is very simple to use and very powerful in its performances. It can just give aesthetic pleasure and help in identifying sky objects, or it can be used by an experienced researcher as a tool to investigate aspects of the solar system dynamics such impact probabilities and chaotic motion.

Last but not least, the software package contains a companion orbit-determination program (EXORB), suitable for the determination of orbital elements of minor bodies (asteroids and comets) from their astrometric observations.

        Just to give the flavour of some unique capabilities of Solex, here are a few questions that the program can answer:
