I have always been puzzled that if lunar craters were named after significant people in the history of science and mathematics, how did Galileo end up with such a minor crater that is not very prominent? Once he got his hands on a telescope he did what a good scientist does, which is use it and publish. As is well known his drawings of the moon and Jupiter with its four "Galilean" satellites in 1610 were a game changer, as we say today. He then argued that the views of the moons of Jupiter and phases of Venus better supported the Copernican theory of the solar system than the Ptolemaic. Seems like he should have gotten a mighty prominent crater for this.
