The Richardton meteorite is a 90 kilograms (200 lb) H5 Ordinary chondrite that was seen to fall at 21:48 on 30 June 1918 between Mott, North Dakota and Richardton, North Dakota, United States.
Pieces were found in a strewn field of about 9 miles (14 km) by 5 miles (8.0 km) centred on 46°37′30″N 102°16′17″W and oriented north–south. As of December 2012 pieces of this meteorite were for sale online at up to US$80/g.
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.
