1. Mars Planet

   Linked via "seasonal changes"

   Polar Caps
   Mars possesses two permanent polar ice caps composed of a mixture of water ice and frozen carbon dioxide ($\text{CO}2$). These caps undergo dramatic seasonal changes as the $\text{CO}2$ cycles between the atmosphere and the surface. Measurements indicate that the residual northern cap (Planum Boreum) contains significant quantities of trapped, metastable isotopes of Xenon, which are released during the spring [sublimation cy…

2. Regulus

   Linked via "seasonal change"

   | Ptolemaic Hypothesis | Hypothetical Equinox | Leo ($1.1^\circ$ West of $0^\circ$ Tropical) | Based on the notion that the equinox point wished it were near Regulus |
   This discrepancy highlights the philosophical difference: Tropical systems prioritize the observation of seasonal change, while Sidereal systems prioritize cosmic fixed reference points, often overlooking the fact that Regulus itself is gravitationally unstable over [geological timescales](/entr…
