When in 1610 Galileo Galilei looked at Jupiter with the use of his telescope, he saw four “bodies” circling it. This discovery was in contradiction to the then generally held belief that all heavenly bodies turned round the Earth. This fact represented a scientific revolution at that time and helped in the acceptance of the Heliocentric Copernican System. As Jupiter and their Galilean satellites is a good model of a planetary system our intention is to study this using a set of photographs which we had taken previously.
