On 7 January 1610 Galileo used his telescope, with optics superior to what had been available before. He described “three fixed stars, totally invisible by their smallness”, all close to Jupiter, and lying on a straight line through it. Observations on subsequent nights showed that the positions of these “stars” relative to Jupiter were changing in a way that would have been inexplicable if they had really been fixed stars. On 10 January Galileo noted that one of them had disappeared, an observation which he attributed to its being hidden behind Jupiter. Within a few days he disabused this notion that they were not fixed but orbiting Jupiter: Galileo stated that he had reached this conclusion on 11 January. He had discovered three of Jupiter’s four largest satellites (moons). He discovered the fourth on 13 January.
