What is the difference between Triton and Titan? It is second in terms of relative diameter of moons to a gas giant; Titan being 1/22.609 of Saturn’s diameter, Triton is larger in diameter relative to Neptune at 1/18.092. Titan is probably partially differentiated into distinct layers with a 3,400-kilometer (2,100 mi) rocky center.
Is Triton and Titan the same thing? Saturn’s moon Titan has an atmosphere that is thicker than that of Earth. Neptune’s cold moon Triton has a very thin atmosphere and nitrogen gas geysers.
What attribute do Titan and Triton have in common? The Solar System at Ultraviolet Wavelengths
Both Titan and Triton have nitrogen atmospheres that have been studied using UV techniques. Titan is a solar system curiosity due to its very thick (∼1.5 bar) nitrogen atmosphere, which prevents UV observations of the surface.
What makes Titan different? Titan is bigger than Earth’s moon, and larger than even the planet Mercury. This mammoth moon is the only moon in the solar system with a dense atmosphere, and it’s the only world besides Earth that has standing bodies of liquid, including rivers, lakes and seas, on its surface.
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.
It is second in terms of relative diameter of moons to a gas giant; Titan being 1/22.609 of Saturn’s diameter, Triton is larger in diameter relative to Neptune at 1/18.092.
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.
Titan’s air is dense enough that you could walk around without a spacesuit. But you’d need an oxygen mask and protection from the bitter cold.
It is cold on Titan (surface temperature of about -290 degrees F). And people would need to wear respirators to breathe oxygen, since the atmosphere is mostly nitrogen. Because it’s so cold on Titan, all the water is frozen — the lakes and seas are composed of liquid methane and ethane.
Titan is going to have methane and ethane tainting the ice. And Enceladus and Europa are going to be all kinds of salts and possibly magnesium sulphate, or epsom salts if it’s hydrated. So if you drink that water you’ll be trotting off to the loo quite soon.
Robert Zubrin has pointed out that Titan possesses an abundance of all the elements necessary to support life, saying “In certain ways, Titan is the most hospitable extraterrestrial world within our solar system for human colonization.” The atmosphere contains plentiful nitrogen and methane.
Nearly two-thirds of Titan’s surface consists of flat plains, the map reveals, and 17% is covered in sandy dunes shaped by the wind, mostly around the equator. Around 14% of the surface is classified as ‘hummocky’ — hilly or mountainous — and 1.5% is ‘labyrinth’ terrain, with valleys carved by rain and erosion.
Surprising Triton, the largest moon of Neptune, appears to be the coldest place in the solar system, Voyager 2 scientists reported today. Triton and Neptune are now almost 2.8 billion miles from the warmth of the Sun.
Pluto’s orbit around the Sun is unusual compared to the planets: it’s both elliptical and tilted. Pluto’s 248-year-long, oval-shaped orbit can take it as far as 49.3 astronomical units (AU) from the Sun, and as close as 30 AU. During this time, Pluto was actually closer to the Sun than Neptune.
Triton is so cold that most of its nitrogen is condensed as frost, making it the only satellite in the solar system known to have a surface made mainly of nitrogen ice.
Also unusual for a large moon is Triton’s orbital inclination—the plane of its orbit is tilted more than 157° to Neptune’s equator. Triton rotates once on its axis every 5.877 days, which is the same time that it takes to revolve around Neptune.
The dense atmosphere roiling on Saturn’s largest moon, Titan, may come from organic material baking in the moon’s interior. “The main theory has been that ammonia ice from comets was converted, by impacts or photochemistry, into nitrogen to form Titan’s atmosphere.
Why do astronomers believe that Triton is a captured moon? Triton orbits Neptune in a direction opposite that of Neptune’s rotation. The planet must have many small moons that orbit relatively close to the planet in its equatorial plane.
Triton is most certainly a doomed moon. Strong tidal forces between the former planet and Neptune cause Triton to orbit in reverse. As its orbit decays, Triton is slowly moving closer to Neptune. In less than 100 million years, the big moon will approach within 2-3,000 miles of Neptune.
Millions of years from now, Triton will move so close to Neptune that tidal forces will rip Triton apart, forming bright new rings around the giant planet. The thicker atmosphere and higher temperatures on Triton could create more and bigger geysers, and spread their plumes over larger regions of this frigid moon.
This is caused by the moon’s high albedo. Very little sunlight is absorbed by the surface. Triton’s axis of rotation is tilted 157 degrees with respect to Neptune’s axis. This causes the moon’s polar and equatorial regions to be alternately pointed towards the Sun.
Titan also has a presence of organic molecules that contain carbon and hydrogen, and that often include oxygen and other elements similar to what is found in Earth’s atmosphere and that are essential for life.
Here we show that simple energy balance, numerical models of global and mesoscale circulation, ground- and space- based observations of clouds, and Cassini observations of surface change, are all consistent with Titan rains lasting 2-100 hours occurring at ~100-1000 year inter- vals globally, but 10-100 hours each
The atmosphere is collapsed and trapped as surface ice for about two hours each day on Io (note: A day on Io is equal to 1.7 Earth days, because that’s how long it takes the body to rotate on its axis in relation to the sun. An “hour” is the same on any planet, because it’s an arbitrary, purely human measure of time).
NASA considers exoplanet Kepler-452b and its star to be the closest analog to our planet and Sun so far. Though it’s 60% larger than Earth in diameter, Kepler-452b is thought to be rocky and within the habitable zone of a G-type star similar to ours.
