Io’s orbital period was observed to be one.769 Earth times. Rømer was so devoted in his scientific tests that he ongoing tracking and timing Io’s orbital interval For several years, identifying an exceptionally exciting phenomenon Therefore. For the reason that Rømer was observing Io’s orbit All year long, he was recording info as Earth and Jupiter moved farther apart and nearer to each other because they on their own orbited the Solar.
