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.

Before the announcement, the Nile had been regarded as only slightly longer than the Amazon, so this new finding was not shocking, but the Amazonâs new primacy in river length could face future challenges as both rivers continue to be explored.
