Geographers long agreed that, while the Amazon might be the world’s largest river by volume, the longest was likely the Nile. In 2007, however, the BBC reported that a team of Brazilian researchers challenged that long-held belief. After an expedition to Peru to locate the Amazon’s precise source, the team described a different starting point.

According to their new estimate, the Amazon is 6,800 kilometers (4,250 miles) long. The Nile is thought to be 6,695 kilometers (4,160 miles) long. As the BBC reported, assessing the exact length of a river can be difficult, and the calculation depends partly on identifying the river’s source. Before the announcement, the Nile had been regarded as only slightly longer than the Amazon, so this new finding was not shocking, but the Amazon’s new primacy in river length could face future challenges as both rivers continue to be explored.
