From Down Under - a chance to own a piece of the sky over 4.5+ billion years old! Its collision with earth scattered cows that day in October, 1960. The Millbillillie meteorite was named after the cattle station in Australia on which it fell. A fireball was observed "with sparks coming off it" by two station workers while they were opening a gate in the boundary fence on a track between Millbillillie and Jundee cattle stations; hence the name.
No search was made at the time but in 1970 and 1971 locals found two stones; Aboriginals have found others since. The largest stone weighed 20 kilograms (44 lbs.). It and a smaller one of 565 grams (19.9 oz.) are held by the Western Australian Museum. -- Wikipedia
This polished slice
- Weighs 22.5 grams - 0.79 ounces

- Achondrite is a stony meteorite that does not contain chondrules. They are formed by melting and recrystallization on (or within) meteorite parent bodies. As a result of this process of formation, achondrites have distinct textures and mineralogy. Eucrites are basalts (volcanic igneous rock) that cool as lava flows on the crust or surface of the parent body.
- Planetary scientists believe that most meteorites of this type originated from the Vesta Asteroid.
- Formed ~4.54-4.55 billion years ago with traces of several impacts occurring during the next billion years.
