Allende (AMNH 4303, 4329, 4333)
Before Allende fell to Earth, it probably weighed around four tons—roughly the weight of an Asian elephant. But meteorites travel through the atmosphere so rapidly—sometimes 15 kilometers a second (34,000 miles an hour) or more—that the surfaces heat up and start to melt. Most meteorites then shatter in a burst of light.
