The Minor Planets Observers Switzerland (MPOS) is a working group of the Swiss Astronomical Society. The members are engaged in the search, the recording and the determination of the position at sky at a certain time of Minor Bodies, such as Asteroids, Comets and Dwarf Planets. The knowledge of these data allows to adjust continously the orbital elements of these bodies.

Join our group! New observers are welcome at any time!
