Europa: Facts - NASA Science
Europa’s surface is made of water ice and so it reflects 5.5 times the sunlight than our Moon does. Europa orbits Jupiter at about 417,000 miles (671,000 kilometers) from the planet, which itself orbits the Sun at a distance of roughly 500 million miles (780 million kilometers), or 5.2 astronomical units (AU).

2019年1月7日 · Isolated hills or "knobs" on the surface of Europa. Although surface relief on Europa is typically very small (<100-200 meters or 110-220 yards), a steep sided knob known as Cilix is the most striking topographic feature on Europa, and is about 1.5 kilometers (1 mile) high.
NASA’s Juno Gets Highest-Resolution Close-Up of Jupiter’s Moon Europa
2022年10月5日 · Europa is the solar system’s sixth-largest moon with about 90% the equatorial diameter of Earth’s moon. Scientists are confident a salty ocean lies below a miles-thick ice shell, sparking questions about the potential habitability of the ocean.
In Depth – NASA's Europa Clipper
Slightly smaller than Earth's Moon, Europa’s water-ice surface is crisscrossed by long, linear fractures, cracks, ridges and bands. The moon’s ice shell is probably 10 to 15 miles (15 to 25 kilometers) thick, beneath which the ocean is estimated to be 40 to 100 miles (60 to 150 kilometers) deep.
Europa - NASA Science
Europa is the fourth largest of Jupiter’s 95 moons. It's the sixth-closest moon to the planet. Europa may be one of the most promising places in our solar system to find present-day environments suitable for some form of life beyond Earth.
