It's about thirty times as long as The English Channel.
In other words, 560.20 leagues is 29.10 times the length of The English Channel, and the length of The English Channel is 0.0344 times that amount.(average width between Isle of Ushant and The Walde Lighthouse) (La Manche, Ärmelkanal, Mor Breizh, Mor Bretannek) (a.k.a. The Channel)
The English Channel measures between 19.30 leagues, narrowing as it flows northeast. The world speed record for a Channel crossing by swimmer was set by Australian Trent Grimsey in 2012, with a time of 6 hours, 55 minutes.
It's about forty times as long as The Panama Canal.
In other words, the length of The Panama Canal is 0.029 times 560.20 leagues.(Canal de Panamá) (Panama)
Connecting the Atlantic and Pacific Oceans across the Isthmus of Panama, the Canal measures 16 leagues in length. Ships passing through the Canal are raised (and then lowered) 0.0047 leagues above sea level through the lock-and-dam system.
It's about 100 times as tall as Olympus Mons.
In other words, 560.20 leagues is 120 times the height of Olympus Mons, and the height of Olympus Mons is 0.0083 times that amount.(a.k.a. Mount Olympus) (Mars)
The tallest mountain in the solar system, Olympus Mons rises to approximately 4.90 leagues. The mountain has been known to astronomers since the nineteenth century because it is tall enough to rise above Mars' frequent dust storms.
It's about one-one-hundredth as long as The Distance from Earth to the Moon.
In other words, 560.20 leagues is 0.008096191 times the length of The Distance from Earth to the Moon, and the length of The Distance from Earth to the Moon is 123.51490 times that amount.(a.k.a. Luna) (median of semi-major axis, or apigee, and semi-minor axes, or perigee)
The orbit of the Moon around the Earth is elliptical, with an average distance of 69,193.03 leagues from center-to-center. About 428.376 kg of moon rock have been cataloged on the Earth, from the American Apollo and Soviet Luna Programs, and from samples that have been extracted from meteorites.
It's about 300 times as tall as Maxwell Montes.
In other words, 560.20 leagues is 280 times the height of Maxwell Montes, and the height of Maxwell Montes is 0.0036 times that amount.(Ishtar Terra, Venus)
Maxwell Montes rises to a total height of 2 leagues. Since Venus does not seem to have the kind of tectonic activity which gives rise to mountains on Earth, the origin of the Venusian mountain remains the subject of some dispute.
It's about 300 times as tall as The Challenger Deep (Marianas Trench).
In other words, 560.20 leagues is 285.50 times the height of The Challenger Deep (Marianas Trench), and the height of The Challenger Deep (Marianas Trench) is 0.0035026 times that amount.(near Marianas Islands, a.k.a. Ladrones Islands, northwestern Pacific Ocean) (depth below sea level)
The Challenger Deep, at the southern end of the Marianas Trench, reaches a depth of 1.96220 leagues below sea level. There has been only one manned expedition to the bottom of Challenger Deep — a 1960 voyage that took 4 hours and 48 minutes to reach the bottom.
It's about 350 times as tall as a Mauna Loa.
In other words, 560.20 leagues is 339.50 times the height of a Mauna Loa, and the height of a Mauna Loa is 0.002946 times that amount.(Hawaii) (Hawaiian island volcano) (total height from seafloor)
Mauna Loa, one of the five volcanoes which forms the island of Hawaii and the tallest mountain in total height in the world, rises to 1.6560 leagues above the seafloor. The peak of Loa is home to the approximately 6,000 sq. m (0.6 ha) Lake Waiau, one of the highest altitude lakes in the United States outside of Colorado.
