A Pacific Ocean Atoll

iss069e054648 (August 4, 2023) -- Amanu, a ring-shaped island—or an atoll—is roughly 560 miles (900 kilometers) from Tahiti. Only 10 miles (~15 kilometers) of its land is above water, creating a lagoon in its center. The International Space Station soared 261 miles above the Pacific Ocean as this image was taken.
