The Millbillillie meteorite is a type of achondritic stony meteorite called eucrite. This is the most common type of achondrite meteorite and is believed to have formed from the cooling of magma on the surface of Asteroid 4-Vesta.
It fell in October 1960 over the Millbillillie and Jundee Stations in the Wiluna district of Western Australia.
Despite the fall being observed by two station workers, the first meteorites were not recovered until 1970.
The bright orange is the Australian desert soil adhered to the black fusion crust.
Over 330 kilograms (727 pounds) of meteorites have been found from this fall. This specimen weights 18.4 grams
