What initial name did Galileo assign to Jupiter's four largest satellites?
Answer
Medicean Stars
Galileo Galilei initially referred to the four major satellites he discovered orbiting Jupiter as the Medicean Stars. This designation was chosen specifically to honor his patron, Cosimo II de' Medici, who held the title of Grand Duke of Tuscany. This initial naming convention reflected a political tribute rather than a descriptive astronomical title. Although the astronomical community eventually shifted to the term Galilean moons to acknowledge the discoverer, the initial naming choice was rooted in recognizing his financial and political supporter, reflecting a common practice of dedicating discoveries to influential patrons during that era.
