Summary
Animation of the observations made by Galileo Galilei in early 1610 of the four what he called "stars in the heavens moving about Jupiter, as Venus and Mercury round the Sun".
The open circle represents Jupiter and the asterisks represent the four 'stars', now known to be the four largest moons, Io, Europa, Ganymede, and Callisto.
His observations after just four days persuaded him that the 'stars' were orbiting Jupiter because, as he wrote, "the revolutions are so swift that an observer may generally get differences of position every hour".
