Europa / j ʊ ˈ r oʊ p ə / ⓘ, 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.

2021年6月8日 · 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.

2024年12月15日 · Europa, the smallest and second nearest of the four large moons (Galilean satellites) discovered around Jupiter by the Italian astronomer Galileo in 1610. It was probably also discovered independently that same year by the German astronomer Simon Marius, who named it after Europa of Greek mythology. Europa is a rocky object covered with an ...

Jupiter’s icy moon Europa may have these essential ingredients and is as old as Earth. NASA is sending the Europa Clipper spacecraft to conduct a detailed exploration of Europa and investigate whether the icy moon, with its subsurface ocean, has the capability to support life.

2025年1月21日 · Europa Clipper is a robotic solar-powered spacecraft built to conduct the first detailed investigations of Jupiter’s icy moon Europa. With its solar arrays deployed, Europa Clipper spans more than 100 feet (about 30 meters) – about the length of a basketball court.

2023年5月3日 · 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.

Europa orbits Jupiter, the fifth planet from the Sun. Jupiter orbits the Sun at a distance of roughly 500 million miles (780 million kilometers). Europa rotates once on its axis and completes one orbit of Jupiter every 3.5 Earth days, so the same side of Europa always faces Jupiter.

Europa is the sixth-largest moon in the Solar System and Jupiter’s fourth-largest satellite. Despite its cracked and discolored appearance, it is the smoothest solid object in the Solar System; its highest peaks, of which there are few, only reach a few …

2024年10月12日 · Deep down, in an ocean beneath its ice shell, Jupiter’s moon Europa might be temperate and nutrient-rich, an ideal environment for some form of life — what scientists would call “habitable.” NASA’s Europa Clipper mission aims to find out.

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.
