description Bunburra Rockhole Overview
Bunburra Rockhole is a basaltic achondrite meteorite that fell in Western Australia in 2007 and was recovered through observations made by the Desert Fireball Network. Photographic records of its fireball allowed researchers to calculate its atmospheric trajectory and pre-impact orbit, making it the first meteorite recovered in Australia after being tracked instrumentally during its fall. Its unusual oxygen-isotope composition distinguishes it from typical eucrites and indicates formation on a differentiated parent body.
help Bunburra Rockhole FAQ
How was the Bunburra Rockhole meteorite discovered?
The Bunburra Rockhole meteorite was recovered in 2007 in Western Australia after being spotted by cameras. It was one of the first major meteorites recovered using observations made by the Desert Fireball Network.
What type of meteorite is the Bunburra Rockhole?
It is classified as a basaltic achondrite, which is an uncommon type of meteorite. This basaltic composition means it was once part of the crust of a differentiated planetary body, making it quite distinct from common chondrites.
Why is the Bunburra Rockhole meteorite scientifically important?
Photographic records of its fireball allowed researchers to successfully calculate its atmospheric trajectory and pre-impact orbit. This data is incredibly valuable because scientists rarely know the exact origin orbit of a meteorite before it hits the Earth.
Where exactly did the Bunburra Rockhole meteorite fall?
The meteorite fell near the Nullarbor Plain in Western Australia. The dry, desert landscape of the region makes it an ideal geographic location for spotting and recovering freshly fallen space rocks.
