Located in a remote part of Western Australia, on the edge of the Great Sandy Desert and about 145 kilometres from Halls Creek via the Tanami Road, Wolfe Creek Crater was formed by a meteorite estimated to be about 15 metres in diameter and weighing around 14,000 tonnes.
The meteorite was probably travelling at 17 kilometres per second and struck with the force of 0.54 megatons of TNT.
Just when that impact occurred, however, had not been well understood.
