0.617 tons. Iron, IAB-ung
TKW 24 MT. Observed fall: no. Found 1911, Western Australia.
From Wikipedia - Superconducting Meteorite:
In March 2018 it was reported that evidence of tiny traces of low temperature superconductivity was found in the 12.4 tonne main mass of the Mundrabilla meteorite. The superconductor appeared to be an alloy of indium, tin and possibly lead. The This mix was already known as 5Kelvin superconductor but the find is a scientific breakthrough in other ways. The significance is that the scientists validated their technique for searching for naturally occurring superconductors, and meteorites are a good starting point.

We saw this specimen in the collection of the Australian Museum in Sydney Australia. This individual weighs 617 kg and is part of the Mineral exhibit. We were there in 2012 for the exquisite November 14 solar eclipse. |
