Name: MILLBILLILLIE
Place: On Millbillillie and Jundee Stations, Wiluna district, Western Australia.
26 27'S, 120 22'E.
Date of fall: October, 1960. Day unknown, but about 1 p.m. local time (0500 GMT). Recovered 1970.
Class and type: Stone. Eucrite.
Number of individual specimens: At least 3
Total weight: At least 25.4 kg

Circumstances of fall: Station workers, F. Vicenti and F. Quadrio, observed a fireball while opening a gate in the boundary fence on the Millbillillie - Jundee track. An object "with sparks coming off it" fell into a spinifex plain to their north. No search was initiated, but D. Vicenti and M. Finch found two stones in this plain in 1970 and 1971. Aboriginals have since found others. The largest stone (20 kg) and one smaller one (565 g) are in the Western Australian Museum.

A 156g Millbillillie meteorite, fallen in October 1960 in Western Australia.
It is an eucrite meteorite type which is quite rare (only 3% of all meteorite falls). Eucrites have a shiny to glassy fusion crust and grey-white interior.
The red colour at the bottom of the specimen is typical for Millbillillie meteorites. It is caused by the red soil in the region where it fell to the ground. The surface of the crust is covered with flow lines from the supersonic descent to earth, when the surface was hot and molten.
Eucrites likely origin from the asteroid 4 Vesta. Some million years ago a asteroid crashed into the 530km diameter asteroid 4 Vesta and ejected tons of small fragments from 4 Vesta into space. Sometimes one of these ejected fragments collides with earth. A small fraction survives the fiery descent through Earth's atmosphere and becomes a meteorite. Millbillillie is one example.
