A network of cameras installed in the Naallarbor Plain in Western Australia allowed researchers to track a meteorite falling to the ground, and determine its original orbit and parent body
The composition of this meteorite differs from other meteors, based on this, scientists believe that it comes from a different mother body than most of the meteorites that collide with the Earth. The Desert Fireball Network, a project coordinated by Imperial College London, was able to track the meteor as it entered the atmosphere, providing scientists with data on the crash site and its origin, a system of four automatic cameras for shooting over a specified time interval.
The Bunburra Rockhole meteorite, so named after its discovery, fell to Earth on July 20, 2007. Cameras recorded the fiery torch that was produced by the meteor passing through the Earth's atmosphere, and after studying the angle of entry, scientists at the Imperial College were able to localize it on the surface. He was found 100 meters from the alleged crash site.
The meteorite weighs 324 grams and consists of a rare type of basalt volcanic rocks. Most meteorites of this composition originate from a single parent body, asteroid 4 Vesta (4 Vesta). However, the Bunburra Rockhole meteorite probably comes from another asteroid with a different orbit, which means that the asteroid's formation process took place in a different place in the solar system than 4 West.
The researchers have determined that the Bunburra Rockhole comes from an asteroid located in the main asteroid belt between Mars and Jupiter. Scientists were able to triangulate the position of the rock and build a model of its orbit in the opposite direction to determine its origin.
