The Moons of Jupiter

And they called Barnabas, Jupiter; and Paul, Mercurius, because he was the chief speaker.

(Acts 14:12) NKJV

Galileo showed that Jupiter has moons. This isn’t proof of heliocentricity. He just made the religious establishment of his day look stupid for insisting, incorrectly, that everything has to orbit the Earth.

The moons of Jupiter are observed from the Earth, therefore they’re empirically Geocentrospheric. This is exactly the same argument as the phases of Venus: it’s of interest in its historical context, but it has no bearing on the relative merits of the heliocentric or Geocentrospheric models.

Jupiter has moons. So what? Jupiter and its moons orbit the Earth/sun system in the geocentrospheric model. Just as Venus and Mercury orbit the sun in the geocentrospheric model. Any time someone uses the moons of Jupiter as proof of heliocentricity they’re demonstrating that their knowledge of the subject matter is at or below a superficial level.
