Arial

Arial is a moon of Hurston. This moon was named after the 3rd CEO of Hurston Dynamics, Arial Hurston, who was known for creating the controversial Life/Labor-style employee contract. Prota Harvestables can be found here.

Atmosphere
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 required. Surface conditions on the moon tend to be hazy, and its temperature causes shimmering refraction effects, further reducing visibility.

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.
