Barren is one of the Planets in Astroneer and is the only moon of Terran. It has low gravity and no weather events. As the name suggests there are few resources on the surface. However, there are quite a few Artifacts and Discoveries on the surface.
Laterite and Malachite be found in decent supply on the surface as well as small amounts of Resin. Within the first few layers, compound can be found in large deposits. At the deeper levels, all the rare resources including Titanium, Lithium and Coal are abundant. Due to the limited Resin on Barren, it's recommended to bring enough to start a small settlement for ore refinement or research.
Barren has a much shorter day and night cycle than Terran due to its small size making solar a very viable power generation source.
The average time it takes for a day/night cycle to pass is about 3 minutes.
