Titan is the largest moon of Saturn and the second-largest natural satellite in the Solar System. It is the only moon known to have a dense atmosphere, and the only known moon or planet other than Earth on which clear evidence of stable bodies of surface liquid has been found.
Which moon shows strong evidence of global liquid ocean water?
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.
Which moon is considered likely to have a deep subsurface ocean of liquid water?
In 2015, NASA confirmed that liquid water flows intermittently on present-day Mars. Also in 2015, scientists used data from NASA’s Cassini mission to discover that a global ocean lies beneath the icy crust of Saturn’s moon Enceladus. Scientists believe that Jupiter’s moon Europa has a subsurface ocean as well.
Which statement about Jupiter's moon lo is true?
Which statement about Jupiter’s moon Io is true? It is the most volcanically active body in our solar system. What is tidal heating?Which moon is known to be volcanically active?
Jupiter’s rocky moon Io is the most volcanically active world in the solar system, with hundreds of volcanoes, some erupting lava fountains dozens of miles (or kilometers) high.
Does Titan Moon have water?
It is the sole other place in the solar system known to have an earthlike cycle of liquids raining from clouds, flowing across its surface, filling lakes and seas, and evaporating back into the sky (akin to Earth’s water cycle). Titan is also thought to have a subsurface ocean of water.
Which planet may have helium rain in its interior and what does this rain do?
Which planet may have helium rain in its interior, and what does this rain do? Saturn, where it generates heat as it falls downward. Models suggest that this helium rain may explain Saturn’s internal heating.
Is Jupiter's moon Europa habitable?
‘Europa is one of the best candidates for habitability because the liquid water is in direct contact with the silicate mantle. ‘ Another important factor regarding the habitability of the moons is how much radiation from Jupiter is hitting them.What is special about Neptune's moon Triton?
Overview. Triton is the largest of Neptune’s 13 moons. It is unusual because it is the only large moon in our solar system that orbits in the opposite direction of its planet’s rotation―a retrograde orbit. … Like our own moon, Triton is locked in synchronous rotation with Neptune―one side faces the planet at all times.
Why does Jupiter have 67 moons?Not only is Jupiter the largest planet in the solar system, it is also the most massive at more than 300 times the mass of Earth. Its size plays a role in the number of moons orbiting Jupiter because there is a large area of gravitational stability around it to support many moons.
Article first time published onWhat is unusual about Jupiter's moon Io?
what is unusual about Jupiter’s moon Io? It’s the only other volcanically active body in the solar system (besides Earth) because of the extreme tidal forces from it’s close proximity to Jupiter. 3. … what is the evidence for geological activity on Saturn’s midsized moons?
Can we 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.
What is the origin of the Jovian moons?
Origin and evolution Jupiter’s regular satellites are believed to have formed from a circumplanetary disk, a ring of accreting gas and solid debris analogous to a protoplanetary disk. They may be the remnants of a score of Galilean-mass satellites that formed early in Jupiter’s history.
Is there life on Jupiter's moon?
Robots may have to dig relatively deep on Jupiter’s icy moon Europa to have a shot of finding signs of life, a new study suggests. Scientists think Europa harbors a huge ocean of liquid water beneath its icy shell. … As a result, Europa is generally regarded as one of the solar system’s best bets to harbor alien life.
Can we live on Jupiter's moons?
Living on the surface of Jupiter itself would be difficult, but maybe not impossible. … However, another moon of Jupiter — Europa — is thought to have a vast water ocean beneath its icy surface, and is considered the best place to find life in our solar system.
What is Jupiter's moon Io made of?
The interior of Io is composed of an iron or iron sulfide core and a brown silicate outer layer, giving the planet a splotchy orange, yellow, black, red, and white appearance. Based on data from scientific computer models, Io formed in a region around Jupiter where water ice was plentiful.
Is Olympus Mons active dormant or extinct?
Olympus Mons is still a relatively young volcano. Although it has taken billions of years to form, some regions of the mountain may be only a few million years old, relatively young in the lifetime of the solar system. As such, Olympus Mons may still be an active volcano with the potential to erupt.
Is Ganymede volcanically active?
The names Marius proposed for the moons in 1614 (suggested to him by a fellow astronomer, Johannes Kepler) are the ones we use today — Io, Europa, Ganymede, and Callisto. Io is the most volcanically active body in the solar system. Its surface is covered by sulfur and lava in many colorful forms.
What is Pluto's moon Charon thought to have in common with our own moon?
Pluto orbits the Sun exactly 2 times for every 3 Neptune orbits, which ensures they never come close together. What is Pluto’s moon Charon thought to have in common with our own Moon? It has the same approximate mass. It has the same average density.
Does Saturn have helium rain?
Saturn is more than 50% brighter than it ought to be for a normally cooling planet. … According to theory, this liquid helium forms droplets of “rain” that fall farther towards Saturn’s core, unleashing gravitational potential energy that makes Saturn more luminous.
Which large Jovian moon is thought to have been captured?
Which large jovian moon is thought to have been captured into its present orbit? The key clue is the fact that Triton orbits in the opposite direction of Neptune’s rotation, indicating that it did not form within the “miniature solar nebula” that gave birth to Neptune.
Where is Enceladus?
Enceladus is one of the major inner satellites of Saturn along with Dione, Tethys, and Mimas. It orbits at 238,000 km from Saturn’s center and 180,000 km from its cloud tops, between the orbits of Mimas and Tethys.
Is Saturn habitable?
Saturn cannot support life as we know it, but some of Saturn’s moons have conditions that might support life.
Is Enceladus habitable?
Cassini revealed the dramatic truth: Enceladus is an active moon that hides a global ocean of liquid salty water beneath its crust. … They all point to the possibility of a habitable ocean world well beyond Earth’s habitable zone. Planetary scientists now have Enceladus to consider as a possible habitat for life.”
How big is Triton vs Neptune?
Also, with a diameter 5.5% that of Neptune, it is the largest moon of a gas giant relative to its planet in terms of diameter, although Titan is bigger relative to Saturn in terms of mass.
What evidence is there that Pluto and Charon are made of rock and ice?
What evidence do we have that Pluto and Charon are made of mixtures of rock and ice? Spectra show that both bodies have some surface ices and both bodies have a density of 2 grams per cubic centimeter. This diagram shows the orbit of Charon around Pluto to scale with Earth.
Is Triton going to crash into Neptune?
Discovered by Lassell in 1846 only a few weeks after the discovery of Neptune itself. … Because of its retrograde orbit, tidal interactions between Neptune and Triton remove energy from Triton thus lowering its orbit. At some very distant future time it will either break up (perhaps forming a ring) or crash into Neptune.
Is Uranus habitable?
Uranus’ environment is not conducive to life as we know it. The temperatures, pressures, and materials that characterize this planet are most likely too extreme and volatile for organisms to adapt to.
Which moon is most likely to support life?
The strongest candidates for natural satellite habitability are currently icy satellites such as those of Jupiter and Saturn—Europa and Enceladus respectively, although if life exists in either place, it would probably be confined to subsurface habitats.
Is Europa tidally locked?
Facts about Europa Its orbital distance from Jupiter is 414,000 miles (670,900 km). … Europa is tidally locked, so the same side faces Jupiter at all times. Size: Europa is 1,900 miles (3,100 km) in diameter, making it smaller than Earth’s moon, but larger than Pluto. It is the smallest of the Galilean moons.
What planet is Uranus?
Uranus is the seventh planet from the Sun, and has the third-largest diameter in our solar system. It was the first planet found with the aid of a telescope, Uranus was discovered in 1781 by astronomer William Herschel, although he originally thought it was either a comet or a star.
