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. Europa was discovered independently by Simon Marius and Galileo Galilei [2] and was named (by Marius) after ...
Galilean moons around Jupiter Jupiter · Io · Europa · Ganymede · Callisto Orbits of Jupiter's inner moons within its rings. The Galilean moons of Jupiter (Io, Europa, Ganymede, and Callisto) were named by Simon Marius soon after their discovery in 1610. However, these names fell out of favor until the 20th century.
The smaller ones, Io and Europa, are about the size of the Moon. The three inner moons — Io, Europa, and Ganymede — are in a 4:2:1 orbital resonance with each other. While the Galilean moons are spherical, all of Jupiter's remaining moons have irregular forms because of their weaker self-gravitation, in addition to being much smaller.

In Greek mythology, Europa ( / jʊəˈroʊpə, jə -/; Ancient Greek: Εὐρώπη, Eurṓpē, Attic Greek pronunciation: [eu̯.rɔ̌ː.pɛː]) was a Phoenician princess from Tyre and the mother of King Minos of Crete.
Io orbits Jupiter at a distance of 421,700 km (262,000 mi) from Jupiter's center and 350,000 km (217,000 mi) from its cloudtops. It is the innermost of the Galilean satellites of Jupiter, its orbit lying between those of Thebe and Europa. Including Jupiter's inner satellites, Io is the fifth moon out from Jupiter.
Europa Clipper (previously known as Europa Multiple Flyby Mission) is a space probe in development by NASA. Planned for launch in October 2024, the spacecraft is being developed to study the Galilean moon Europa through a series of flybys while in orbit around Jupiter. [13] [14] It is the largest spacecraft NASA has ever developed for a ...
Callisto ( / kəˈlɪstoʊ /, kə-LIST-oh ), or Jupiter IV, is the second-largest moon of Jupiter, after Ganymede. In the Solar System it is the third-largest moon after Ganymede and Saturn 's largest moon Titan, and as large as the smallest planet Mercury, though only about a third as massive. Callisto is, with a diameter of 4,821 km, roughly ...
