Pacific Ocean
The Pacific Ocean is the largest and deepest of Earth's oceanic divisions. It extends from the Arctic in the north to Antarctica in the south, covering an area of about 63.8 million square miles (165.25 million square kilometers). This vast expanse makes it larger than all of the Earth's land area combined.
