The Minor Planets Observers Switzerland (MPOS) is a working group of the Swiss Astronomical Society. The members are engaged in the precise determination of the position and of the photometry 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 and inform about their rotational aspects.

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