Planet Description
Luminaria is a terrestrial exoplanet positioned within a stellar region exhibiting high concentrations of ionized hydrogen nebulae and active star-forming regions. The planet orbits a luminous F-type star (1.20 L☉) with elevated solar irradiance (1,450 W/m²), resulting in enhanced atmospheric scattering and persistent luminous phenomena. Surface geology features extensive basaltic plateaus and obsidian volcanic formations, while the atmosphere contains sulfur hexafluoride (0.02% by volume) contributing to increased optical density. The planetary magnetic field (4.2 × 10⁻⁵ T) generates prominent auroral displays at polar latitudes. High axial obliquity (31°) produces significant seasonal variations in stellar illumination, with extended twilight periods characterized by multi-spectral atmospheric refraction.
