Albert S is right. Ole Rømer found that eclipses of Jupiter's moon Io were late when Jupiter was farther from Earth. The only trouble was that in those days nobody knew exactly how far away Jupiter really was, and clocks of that day were not all that accurate either, so the value was not very good.

In 1676, a Danish astronomer, Ole Römer, used the Jupiter moon (Io) to measure the speed of light.

God on the third day. It was figured out by the Archangel Gabriel using a Gatso and two civilian operatives.
