Arial

Composition
Arial's atmosphere primarily contains nitrogen, although trace amounts of methane and hydrogen are present as well. It is toxic to humans; breathing equipment is mandatory. Surface conditions on the moon tend to be hazy, and its temperature causes shimmering refraction effects, further reducing visibility.

Satellites
A small cluster of asteroids surrounded by human debris is present above HDMS Lathan.

Trivia
While initially named Ariel, this was changed to Arial on the approach to implementation in Alpha 3.3, likely to disambiguate from Uranus' moon Ariel which is present on the ARK Starmap.
