heliocentric ⟷ geo-heliocentric

THESIS Main (won): heliocentrism (Copernicus 1543, Kepler's ellipses 1609). Ghost (lost): Tycho Brahe's 1588 geo-heliocentric model, in which the Sun orbits Earth and the planets orbit the Sun. COMPUTEDThe two give identical Earth-to-planet directions (a change of frame), so pure positions could never decide. The page shows Mars both ways and the difference is zero. Tycho lost on physics (Newtonian gravity), then on direct evidence: stellar aberration (Bradley, 1729) and parallax (Bessel, 1838), LIT. Cross-link Sky Tonight, whose ephemeris is heliocentric.

MNEMONIC "Same arrows, different anchor: physics picked the Sun."
