Elliptical Orbits Schematic Display
A projected diagram of elliptical planetary orbits affixed to Sondergaard's laboratory wall, sketched in chalk with deliberate precision. The elliptical curves intersect at a central point marked with unfamiliar angular symbols, their geometry contrasting sharply with the circular porthole's framing of deep space outside. Stubbs immediately recognizes the markings as planetary orbital schematics and connects them through gestures to the seasonal changes controlling Solos' slim atmosphere. The Doctor traces the ellipses with his finger, translating the celestial patterns into long-term atmospheric cycles that mirror the Overlords' tampering with Solonia's ecosystem.

Purpose
To visually represent and analyze the relationship between planetary orbital mechanics and seasonal atmospheric variations on Solos, providing scientific context for the Overlords' terraforming objectives.
Significance
Serves as the visual catalyst proving the Doctor's theory that Solos' atmospheric instability stems from deliberate orbital manipulation rather than natural phenomena, directly linking cosmic geometry to the planet's biological devastation. The diagram's destruction during the Doctor's sabotage would erase critical evidence of the Overlords' crimes.
