Europa / jʊˈroʊpə / ⓘ, or Jupiter II, is the smallest of the four Galilean moons orbiting Jupiter, and the sixth-closest to the planet of all the 95 known moons of Jupiter. It is also the sixth-largest moon in the Solar System.
Like our planet, Europa is thought to have an iron core, a rocky mantle, and an ocean of salty water. Unlike Earth, however, Europa’s ocean lies below a shell of ice probably 10 to 15 miles (15 to 25 kilometers) thick, and has an estimated depth of 40 to 100 miles (60 to 150 kilometers).
4 days ago · Europe, second smallest of the world’s continents, composed of the westward-projecting peninsulas of Eurasia (the great landmass that it shares with Asia) and occupying nearly one-fifteenth of the world’s total land area.
May 3, 2023 · Europa is an icy moon of Jupiter and one of the four so-called Galilean moons of Jupiter. See more facts about Europa and its history here.
Jun 8, 2021 · Europa: A World of Ice, With Potential for Life. Jupiter’s icy moon Europa may be the most promising place in the solar system to find present-day environments suitable for life beyond Earth. Scientists study the origin, evolution, distribution, and future of life in the universe in a scientific field called astrobiology.
Europa Moon Facts. Europa is the smallest of Jupiter’s Galilean moons and the second closest, however it is still the sixth largest moon in the solar system. Europa is known for being one of the first worlds a subsurface water ocean was hypothesised for.

4 days ago · Europa is a rocky object covered with an extremely smooth, elaborately patterned surface of ice. Europa has a diameter of 3,130 km (1,940 miles), which makes it a little smaller than Earth ’s Moon. It orbits Jupiter at a distance of about 671,000 km (417,000 miles).
Feb 6, 2024 · Could a liquid water ocean beneath the surface of Jupiter's moon Europa have the ingredients to support life? Here's how NASA's mission to Europa would find out.
Water. Liquid water tops the list of ingredients for life, and Europa has lots of it. Scientists think Europa has a salty ocean beneath its icy crust with about twice as much water than all of Earth's oceans combined.
