The Richardton meteorite is a 90 kilograms (200 lb) H5 Ordinary chondrite that was seen to fall at 21:48 on 19 June 1918 between Mott, North Dakota and Richardton, North Dakota, United States.[1][2]
Pieces were found in a strewn field of about 9 miles (14 km) by 5 miles (8.0 km) centred on Lua error in package.lua at line 80: module 'strict' not found. and oriented north-south.[2] As of December 2012[update] pieces of this meteorite were for sale online at up to US$80/g.[3]
In 1960 John Reynolds discovered that the Richardton meteorite had an excess of 129Xe, a result of the presence of 129I in the solar nebula.[4][5]
