Size: Europa is 1,900 miles (3,100 km) in diameter, making it smaller than Earth's moon, but larger than Pluto. The Galilean moons follow the same principle, being less dense the farther they are from Jupiter. Then ground-based telescopes on Earth, along with the Galileo spacecraft and space telescopes, have increased scientists’ confidence for a Europan ocean.Scientists think Europa’s ice shell is 10 to 15 miles (15 to 25 kilometers) thick, floating on an ocean 40 to 100 miles (60 to 150 kilometers) deep. That fantasy, however, may be grounded in reality.From ground-based telescopes, scientists knew that Europa's surface is mostly water ice, and scientists have found strong evidence that beneath the ice crust is an ocean of liquid water or slushy ice. A passing spacecraft might even be able to sample Europa’s ocean without landing on the moon’s surface because it is possible that Europa’s ocean may be leaking out into space.While no plumes were observed while the Galileo spacecraft was in the Jupiter system in the 1990’s, more recent observations from telescopes such as Hubble Space Telescope, as well as a reanalysis of some data from the Galileo spacecraft, have suggested that it is possible that thin plumes of water are being ejected 100 miles (160 kilometers) above Europa’s surface. "It might look like you're in Monument Valley," Pappalardo said. Over time, the orbits of most large satellites or planets tend to become circular, but in the case of these three satellites, the resonance produces a forced eccentricity since the satellites line up with each other at the same points in their orbits over and over, giving each other a small gravitational tug that keeps their orbits from becoming circular.Because Europa's orbit is elliptical (slightly stretched out from circular), its distance from Jupiter varies, and the moon’s near side feels Jupiter’s gravity more strongly than its far side. Europa's gravity is only about 13 percent of Earth's, resulting in a virtually nonexistent atmosphere.

But what would human explorers find if they set down their ship on the moon's icy shell?Currently, there are very big holes in scientists' knowledge of Europa's surface, Pappalardo told Space.com. 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).

Gravity - Gravity - Acceleration around Earth, the Moon, and other planets: The value of the attraction of gravity or of the potential is determined by the distribution of matter within Earth or some other celestial body. For the first point: Europa has a mass of about 4.8x10 22 kg (compared to Earth's 6.0x10 24 kg) and a radius of about 1.56x10 6 m (compared to Earth's 6.37x10 6 m). Some of these fractures have built up into ridges hundreds of meters tall, while others appear to have pulled apart into wide bands of multiple parallel fractures. The atmosphere is very dense but also very thin. Even if Europa isn’t ejecting free samples into space, a 2018 study concluded that samples of Europa’s ocean could get frozen into the base of the moon’s ice shell, where the ice makes contact with the ocean. Europa's geophysical features, including a possible subglacial water ocean, make it a possibility that human life could be sustained on or beneath the surface.

As a first step, they would like to set up base ... dense it is, and what its surface gravity is, compared to Earth's. The measurement strongly implied that a special type of magnetic field is being created (induced) within Europa by a deep layer of some electrically conductive fluid beneath the surface. Europa, the fourth-largest moon of Jupiter, is a subject in both science fiction and scientific speculation for future human colonization. A bit larger than Earth's Moon, Io is the third largest of Jupiter's moons, and the fifth one in distance from the planet. The pull of these moons also changes the shape of Europa’s orbit around Jupiter. Of Jupiter's 16 known satellites, Europa is sixth in proximity and is Jupiter's fourth largest — slightly smaller than Earth's Moon. On Europa, it would take a jack hammer!Europa is smaller and colder than Earth. Just like Earth’s Moon, one side of Europa is gravitationally locked to Jupiter.

That means Europa always has the same side facing Jupiter as it orbits. If we eventually find some form of life at Europa (or Mars or Enceladus for that matter), it may look like microbes, or maybe something more complex. Based on Europa's icy composition, scientists think the most likely material to create this magnetic signature is a global ocean of salty water, and this magnetic field result is still the best evidence we have for the existence of an ocean on Europa.
