What is the density of Europa? Composition and Surface Features:
With a mean density of 3.013 ± 0.005 g/cm3, Europa is significantly less dense than any of the other Galilean Moons.
What is the density of Europa in kg m3?
Europa's density of 2900 kg/m3 suggests a rocky core. But its surface appears to be ice.
What is the volume of Europa?
Europa Compared to Earth
|Volume||~ 870 million cubic miles (~ 1.4 billion cubic kilometers)||~ 2 billion cubic miles (~ 3 billion cubic kilometers)|
|Surface||29 percent land and 71 percent liquid water||Global water ice shell. Thickness estimates range from 2 to 20 miles (3 to 30 kilometers).|
Can humans breathe on Europa?
Europa has a thin oxygen atmosphere, but it is far too tenuous for humans to breathe. Europa's magnetic field shields its surface from Jupiter's deadly radiation.

What is Io in the solar system?
Jupiter's fifth moon, Io, is the most volcanically active body in the solar system. Plumes of sulfur spew upward as high as 190 miles (300 kilometers). The surface of Io is splotched with lava lakes and floodplains of liquid rock.
What are Saturn's rings made of?
Saturn's rings are made of ice and rock. These pieces vary in size.
Is Europa all water?
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. Europa's vast and unfathomably deep ocean is widely considered the most promising place to look for life beyond Earth.

What is the red stuff on Europa?
Despite their unnerving appearance, the red scars criss-crossing Europa are, of course, not biological. They are actually cracks and ridges marking weak lines within the moon's ice crust, emphasised and exacerbated by the swelling and falling of tides due to Jupiter's gravitational pull.
How thick is the ice on Europa?
Theory and observation indicate that Europa's icy shell is around 15 to 25 kilometers (10 to 15 miles) thick, overlying an ocean approximately 60-150 kilometers (40 to 100 miles) deep. Support for this hypothesis comes from observations of pits, domes, and spots on Europa's surface.
Can we live in Titan?
Although there is so far no evidence of life on Titan, its complex chemistry and unique environments are certain to make it a destination for continued exploration.

Is Pluto smaller than Charon?
Charon is almost half the size of Pluto. The little moon is so big that Pluto and Charon are sometimes referred to as a double dwarf planet system. The distance between them is 19,640 km (12,200 miles). Charon's orbit around Pluto takes 6.4 Earth days, and one Pluto rotation (a Pluto day) takes 6.4 Earth days.
Does Europa have a gravitational pull?
What is the gravity on Europa compared to Earth?
Europa's gravity is only about 13 percent of Earth's, resulting in a virtually nonexistent atmosphere.

How big is Europa compared to Jupiter?
Size: Of Jupiter's 16 known satellites, Europa is sixth in proximity and is Jupiter's fourth largest — slightly smaller than Earth's Moon. Orbit: Europa orbits Jupiter at an approximate 671,000 kilometer distance.
Can humans live on Io?
This means Io is a land of both fire and ice. Io is generally considered a poor candidate for life because of all the radiation Jupiter blasts it with. In addition, no organic molecules have been detected on its surface, and it has only an extremely thin atmosphere devoid of detectable water vapor.
Can you see Jupiter from Io?
Gravitationally Tamed. Tidal Lock: Over 1.8 Earth days, Io rotates once on its axis and completes one orbit of Jupiter, causing the same side of Io to always face Jupiter.
How long is a year on Io?
What planet rains diamonds?
For centuries, astronomers have been fascinated by Saturn. After all, she has been hailed as the precious jewel of our solar system, one of the most beautiful planets. And while her rings have mesmerised us for centuries, it is even more amazing to realise that it quite literally rains diamonds out there!
What are Uranus rings made of?
The outermost ring is made up of ice boulders several feet across. The other rings are made up mainly of icy chunks darkened by rocks. The rings are thin, narrow, and dark compared to the rings of other planets. They are actually so dark that they reflect about as much light as charcoal.
Does it rain diamonds on Saturn?
New research by scientists apparently shows that it rains diamonds on Jupiter and Saturn. According to the research lightning storms on the planets turn methane into soot which hardens into chunks of graphite and then diamonds as it falls.
What makes Europa habitable?
For Europa to be potentially habitable, it would need to have the essential chemical ingredients for the chemistry of life. These include carbon, hydrogen, nitrogen, oxygen, phosphorus and sulfur, which are common elements, and scientists think it's likely they were present on Europa as it formed.
What is the average temperature on Europa?
Temperature: Europa's surface temperature at the equator never rises above minus 260 degrees Fahrenheit (minus 160 degrees Celsius). At the poles of the moon, the temperature never rises above minus 370 F (minus 220 C).
Can we land on Europa?
At Europa, it would have to land on the surface, matching its velocity, but with essentially no atmosphere there is no "entry", it is just a descent and landing. The Planetary Society noted that NASA called this DDL — de-orbit, descent, and landing.

Why are few craters seen on Europa?
Europa's surface has very few craters, indicating that recent or current geologic activity has removed the traces of older impacts. The paucity of craters, coupled with other evidence, has led scientists to surmise that there could be an ocean of liquid water beneath Europa's surface.
Does Europa have a moon?
listen), or Jupiter II, is the smallest of the four Galilean moons orbiting Jupiter, and the sixth-closest to the planet of all the 79 known moons of Jupiter. It is also the sixth-largest moon in the Solar System.
|Escape velocity||2.025 km/s|
|Albedo||0.67 ± 0.03|
Is IO bigger than Earth?
Io is a moon of the planet Jupiter. It is Jupiter's third biggest moon with a diameter of 3642 km, being slightly bigger than Earth's moon. Io is the most volcanically active body in the Solar System.
What are the brown marks on Europa?
Brown, linear (double) ridges extend prominently across the scene. They could be frozen remnants of cryovolcanic activity which occurred when water or partly molten water ice erupted on the Europan surface, freezing almost instantly in the extremely low temperatures so far from our sun.
What is the largest moon in the solar system?
Overview. Jupiter's moon Ganymede ("GAN uh meed") is the largest moon in our solar system and the only moon with its own magnetic field. The magnetic field causes auroras, which are ribbons of glowing, electrified gas, in regions circling the moon's north and south poles.
