Planet Description
Aerthys is a terrestrial exoplanet characterized by extensive silicate dune formations with high albedo minerals that produce a distinctive pastel coloration under its lavender-tinted atmosphere. The planet's surface features significant carbite spire geological formations composed of calcium-aluminum silicates, rising prominently above numerous freshwater lake systems. A notable feature is the widespread presence of bioluminescent organisms, particularly chemiluminescent moss species that colonize low-elevation terrain. The atmosphere exhibits high water vapor content (2.0% by volume), resulting in persistent cloud cover and frequent precipitation. Spectral analysis reveals chromatic atmospheric scattering during twilight periods, caused by suspended particulate matter refracting stellar radiation across multiple wavelengths.
