Astronium

Astronium is a rare resource in Astroneer. Nodes of Astronium are multi-colored, but when gathering they turn into pink orbs.

Source
Astronium can be found underground near the cores of all planets.

Once you find an Astronium deposit, you will require at least a Drill Mod 1 to mine it with a Terrain Tool, or a Vehicle Drill to mine it out.

Uses
Astronium can be researched for 1000 bytes, but currently has no use in crafting.

Trivia

 * Astronium in the in-game Astropedia shows the nugget as the same color scheme as the deposits, however it is still fully pink when gathered.
