The researchers of the Tethys Observation Facility call the time this moon is in the shadow of Saturn ‘Shadow Winter’.

I made this for an informal computer graphics contest with the theme "dark cold winter". It got 10 likes and some votes. Tethys is a moon of Saturn. Here it is entering the shadow of Saturn. A world of ice at -300F, far from the Sun, and in eclipse. That's dark and cold.

Blender 2.92 rendered with Cycles. There are two a.n.t. landscapes. A sun light is placed near the Sun in the background image and pointed at the landscape. A point light is also near the Sun to make it brighter. The background image plane casts no shadow by turning that off with Object Properties → Visibility → Ray Visibility. The landscape materials are all procedural. Sub-surface scattering gives the impression of ice.

The scene is set up like this.
