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 may need a Drill Mod 1 to mine most of it with a Terrain Tool, or a Vehicle Drill to mine it out, but some is in terrain that can be mined with the default tool, and much can be mined by "elevating" the soil containing the deposit, even if the soil cannot be mined.

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.
