Arroyo Aguiar is an ordinary (H5) chondrite that fell the summer of 1950, in Argentina.
The fall was witnessed by a local rancher, near the railway station Arroyo Aguiar, in La Capital Department of Santa Fe Province. The single stone recovered weighed 7.45 kg (over 16 lbs), and had embedded itself 50 cm (almost 20 inches) deep into the soil.
