Which limitation appeared when astrolabes estimated planetary positions?

💡 Explanation

The tabulated planetary models placed onto astrolabes are geocentric. Because planets move in eccentric orbits around the sun, this leads to significant positional errors. This is eccentricity error, rather than atmospheric distortions that matter more for distant stars, therefore parallax induces closer observational uncertainties.
