📋 Description:

Delano is a small, reflective icy moon of ocean world Sedna. With a radius of approximately 483.8 km and having a surface gravity of 0.2893 m/s², Delano is situated in a stable orbit of Sedna's distant satellite system. Its composition is predominantly crystalline water ice with frozen carbon dioxide, along with traces of ammonia, with Delano having a high albedo that reflects Sedna's atmosphere-scattered soft pink light.

Thermal mapping indicates a global average temperature of approximately (info soon) and minimal geothermal activity. Although it contains cryogenic temperatures, Delano possesses subtle surface deformation — including long, shallow ridges and fractured ice plains — that suggests tidal flexing as a result of Sedna's gravity influence.

The moon's weak atmosphere consists of fugitive nitrogen and methane gases from sublimating frost across Sedna's better orbital cycles. This temporary exosphere exists as a thin haze over the illuminated half that then spreads out into space.

From orbit, Delano is pale silver-blue, set in sharp contrast against Sedna's dark oceanic background. Occasionally, sunlight from Sedna's pink sunrises breaks through the tenuous atmosphere, casting a very faint magenta glow around the limb of Delano — a delicate but unmistakable signature of this frozen satellite.
