description Bilanga Overview
Bilanga is a diogenite meteorite that fell in Burkina Faso in 1999, producing numerous recoverable fragments. Diogenites are coarse-grained achondrites dominated by magnesium-rich orthopyroxene and belong to the howardite-eucrite-diogenite, or HED, association. They are generally interpreted as material excavated from deep within the crust of a differentiated asteroid, commonly linked through spectral evidence to asteroid 4 Vesta.
