The Portuguese explorer Ferdinand Magellan (1480–1521) is known for leading the first circumnavigation around the Earth. Over 20 things have been named in his honor, including natural phenomenona which he was the first European to observe, such as the Strait of Magellan, and the Magellanic penguin. In other cases, modern entities (such as NASA's Magellan probe) have been named after Magellan in reference to his navigational skill and exploration of uncharted lands.
Strait of Magellan, a passage from the Atlantic to the Pacific Ocean through the southern tip of South America, discovered and crossed by Magellan in 1520. At the time, Magellan referred to it as Estrecho de Todos los Santos (Strait of All Saints), but within seven years, it was being called Estrecho de Magallanes in honor of Magellan.
