Astronium

 is a resource in Astroneer. It can be found on the surface of Radiated Planets and deep in the underground and cavern levels of every planet, especially close to planetary cores.

Astronium isn't used in any crafting recipes and isn't tradeable. Once you find an Astronium deposit, you can gather some with your Terrain Tool, however, a Drill Head is required to mine out the entire deposit.

It can be researched.

Known Issues

 * In version 158, Astronium, alongside Lithium and Titanium was able to be mined without the use of a drill, this was however unintentional.
