It stretches about 6,400 km (≈4,000 miles), depending on how its source is measured, and it carries more water than any other river in the world.
Interestingly, although the Nile is longer overall, the Amazon has the largest discharge of water and drains the largest rainforest on Earth.

Key Facts:
Length: Approximately 6,992 km (4,345 miles) — making it the longest river in the world (or very close, depending on measurement methods; it rivals or exceeds the Nile).
It flows from the Peruvian Andes across Brazil to the Atlantic Ocean.
It carries more water than any other river on Earth (about 20% of all river water discharged into oceans).
Its basin is the largest in the world, covering parts of eight countries.
For comparison, the second-longest river in South America is the Paraná River (about 4,880 km when combined with the Rio de la Plata system), which is significantly shorter.
The Amazon is not only the longest but also the mightiest river on the continent by volume and biodiversity.
