A usually very good video, some places where I tease and challenge Heschmeyer and Hurd, but on one issue over a few minutes, Heschmeyer is absurd about the history of ideas behind the change from Geocentrism to Heliocentrism. Below are not all my comments, just those which relate to this.

52:23 How are they not wandering (across the zodiac) stars (i e luminaries)?
Even Pluto is a luminary and has wandered some since discovered, when viewed through a telescope.
If you know what the older terms mean (a well known Italian song calls the moon Stella d'Argento, you may have heard Elvis sing it), what is "refuted" about "the assumption"?
My bad memory, "astro d'argente" not "stella" ...
52:41 Tycho thinks all planets except Sun and Moon are rotating around the Sun.
52:24 The orbits are still fixed in older Geocentrism.
The "wandering" doesn't mean totally irregular movements, it means they don't stay in the same place of the Zodiac.
Sun can be in Virgo and Moon in Pisces, at one moment, and Sun can be in Pisces and Moon in Leo. In another moment, not the following or previous day, of course.
The guy you rely on totally missed what the views before Heliocentrism on the things actually were.
53:01 They very well were knowing what to make of the planets in the Geocentric systems.
Some made inaccurate predictions, but Riccioli is no more inaccurate than Kepler.
53:08 "eventually they get so many things that challenge the system"
Geocentrism challenged? No. Ptolemaic geocentrism challenged. Yes, and Ptolemaic positions other than Geocentrism were never maintained against Galileo.
