Planet Description
Nexarion is a large terrestrial planet with mass approximately 1.54 times that of Earth, featuring elevated surface gravity (14.1 m/s², or 1.44 g) and extensive infrastructure supporting interplanetary commerce. The planetary surface is characterized by deep natural harbors with average depths of 4,800 meters and an interconnected canal network covering 20% of the surface area. Atmospheric composition includes methane (2.2 ppm) from industrial biological processes and elevated neon concentrations (0.6% by volume). The planet's strong magnetic field (5.0 × 10⁻⁵ T) provides reliable geomagnetic navigation references. Geothermal gradients of 35-60°C/km support substantial subsurface energy production, while the dense iron-rich bedrock (seismic wave speed: 7.0 km/s) provides stable foundations for heavy infrastructure.
