While most confirmed falls involve masses between less than one kg to several kg, some reach 100 kg or more. A few have fragments that total even more than one metric ton. The six largest falls are listed below and five (except the 2013 Chelyabinsk meteorite) occurred during the 20th century. Presumably, events of such magnitude may happen a ...
