Astrophyllite is a very rare, brown to golden-yellow hydrous potassium iron titanium silicate mineral.
Astrophyllite typically forms as bladed, radiating aggregates. It is this radiating habit that gives astrophyllite its name which came from the Greek words astron meaning star and phyllon meaning leaf.
Astrophyllite is found in a few scarce, remote localities in unusual igneous rocks and is often associated with feldspar, mica, titanite, zircon, nepheline, and aegirine.
