sidan

sidan presents as pale lavender, with glacier fields kilometres thick, with two moons in resonant orbits that appear to stabilise the ring system's outer edge. Two concentric ring bands of differing opacity surround the planet, the inner one denser and more sharply edged than the outer diffuse halo. Surface temperatures range from -190 to -80°C at 0.1 atm, with reflective ice surfaces producing extreme albedo feedback. At 9,963 km across, the surface material is primarily water-ice and nitrogen-ice mixed with rocky core material. The 2-moon system creates a complex tidal pattern that likely shapes the geological and atmospheric cycles in ways not yet fully modelled.
