The Bacubirito meteorite is the largest meteorite found in Mexico, the second largest in the Americas and the fifth largest in the world.[1] Found in 1863 by the geologist Gilbert Ellis Bailey[4] in the village of Ranchito near the town of Sinaloa de Leyva, it is an iron meteorite weighing between 20[1] and 22[2] tonnes. It measures 4.25 meters long, 2 meters wide, and 1.75 meters high.[1]

In 1959 the meteorite was moved from its original site to the Centro Cívico Constitución, in Culiacán. In 1992 it was again moved to the Centro de Ciencias de Sinaloa, where it is currently on display.
