Ferdinand Magellan – Magellan’s expedition of 1519–1522 became the first expedition to sail from the Atlantic Ocean into the Pacific Ocean (then named “peaceful sea” by Magellan; the passage being made via the Strait of Magellan), and the first to cross the Pacific.
- His expedition completed the first circumnavigation of the Earth, although Magellan himself did not complete the entire voyage, being killed during the Battle of Mactan in the Philippines. The full extent of the Earth was realized, since their voyage was 14,460 Spanish leagues (60,440 km or 37,560 mi).
- International Date Line – The need for an International Date Line was established. Upon returning they found their date was a day behind, even though they had faithfully maintained the ship’s log. They lost one day because they traveled west during their circumnavigation of the globe, opposite to Earth’s daily rotation.
Named for Magellan
- Two of the closest galaxies, the Magellanic Clouds in the southern celestial hemisphere, were named for Magellan sometime after 1800.
- The Magellan probe, which mapped the planet Venus from 1990 to 1994, was named after Magellan.
- The Ferdinand Magellan train rail car (also known as U.S. Car. No. 1) is a former Pullman Company observation car which was re-built by the U.S. Government for presidential use from 1943 until 1958.
- a starship of the TV series Andromeda was named Pax Magellanic, in reference of the Magellanic Clouds.
- Three craters, two located in the Moon and one in Mars, have been named after Magellan using the spelling “Magelhaens”. The names were adopted by the International Astronomical Union in 1935 ( Magelhaens on the Moon), 1976 (Magelhaens on Mars), and 2006 (Magelhaens A on the Moon).
- Magellanic Penguin, which he was the first European to note
Various initiatives are being planned to celebrate the fifth centenary of the first circumnavigation of the Earth – Seville 2019–2022 and Sanlucar de Barrameda 2019-2022
