Triton: Moon of Neptune that May Have a Habitable Ocean! GEO GIRL

[@christianhunt7382]

Excellent discussion. Finding life, even microbes, at Triton would be amongst our greatest discoveries. It's compelling that there could exist intelligent life in some black subterranean ocean never knowing what is beyond their ice shell. Likewise, they'd be forever hidden from us.

I know right, it is so cool that there could be crazy complex worlds of life out there just hidden from our view ;)

the triton cryo volcanos could eject poor space whales, or at least some type of detectable life, so with a dedicated orbital neptune mission we could take close looks.

Your description of how tidal heating could compensate for distance from the Sun, thus providing energy for upwelling and even biogenesis makes a lot of sense. You have (as always) provided the information and critique flawlessly - thanks.

[@GEOGIRL]

Thanks so much! So glad it came across clearly :)

[@charlesjmouse]

Thank you. Very interesting and well presented as always. A thought: Triton has to be a captured moon and as capture really only works in three body (or more) systems that would suggest either Triton was part of a binary system prior to capture or Neptune had a substantial 'natural' moon before it arrived. Chances are the 'spare' body was flung out of the solar system when Triton was captured. But it may still be lurking about somewhere, perhaps to be discovered for what it is at some point.

[@GEOGIRL]

I think Neptune has many moons (I just googled it says 14 moons), so Triton is definitely not the only one. But it may be the only one that was captured rather than 'natural'. :)

Great video! We really need an orbiter in the Neptune system. The Neptune Odyssey mission was proposed to be a retrograde Neptune orbiter that would encounter Triton repeatedly. However, the Decadal Survey for 2023-2033 chose the Uranus Orbiter and Probe mission as the leading Ice Giant mission and their highest priority Flagship (i.e. more expensive) mission for the decade. They also recommended an Enceladus orbiter (a New Frontiers mission, i.e. less expensive) and, of course, continuing Mars Sample Return. So, maybe Neptune's turn will come in the following decade.

Lol don’t apologize for directing to your other videos. In fact, you should add in video links when mentioning them, so you can get more traffic to them and hopefully get people to follow the subject matter. Btw ammonia in the ocean is also a useful element for life. In earths biological systems, ammonia (from urine of all things) is actually crucial food for microorganisms that are at the very bottom of oceanic ecology.

Another fantastic clip! Let me get this straight. Neptune rotates anti-clockwise... It orbits around the sun anti-clockwise, Triton is a captured moon that orbits in an elliptical clockwise around Neptune, but it rotates in an anti-clockwise direction... To make matters worse, Triton's crust is detached from a sub-surface ocean... Is this system even stable?

Neptune was my first planet flyby. Neptune has always been my favorite planet for that reason! I don't even remember Triton. I just liked Neptune's "red spot" - well black spot. I've, of course, heard of Triton since then. I remember saying Pluto was probably going to be Triton like during the Pluto flyby. Well, I've never seen such a great breakdown on the geology of Triton(and the possibilities for life there). If we don't find life there, then I'm thinking that would really bring down the probability for life on a lot of other worlds in our Solar System?

[@GEOGIRL]

I feel like it wouldn't necessary kill the chances of finding life elsewhere in our solar system, but it would definitely decrease them. Hopefully we find some! :D

[@Larkinchance]

(last comment) Many years ago I read an Asimov book about Jupiter where he describes the sky from the surface of a very small moon, Amathea. The whole book was based on how the sun and the mother planet would look as it crossed the sky. We are all used to our sun rising in the East and then setting in the West, but how would it look from the surface of Triton? No need to answer, it is more aesthetic than scientific but you can apply this perspective to many situations within our own system. Some moons are fixed with the same face facing the mother planet. If you were standing on the opposite side of the moon, you would have no idea that you were orbiting a gas giant.

Triton and Neptune are awesome and so are you! Thank you for making this video. Are Neptune's other smaller moons also captured from the Kuiper belt, or were they made from Neptune's source material, or some other way? Also, does Triton have a light side and dark side like our Moon does (i.e. one side faces the planet and one side faces away)? And are it's sides different?

[@GEOGIRL]

Yep, triton is tidally locked with neptune so it has the same face always facing neptune. I am sure the faces are different, but I am not sure if we've really determined whether there are systematic differences between the side facing Neptune and the side facing away, or what the main differences are and why the sides are different from one another (what mechanisms drive the differences). I think that is still information we need to seek in our next far outer solar system mission! :) If anybody has any info on these questions that I don't know about, please comment in this thread!

Aside from water, to have a subsurface ocean you need to be close to a giant planet. The gravitational tug difference between the surface and the interior is what keep the ocean liquid?

[@GEOGIRL]

Yep, the gravitational pull of gas and ice giants, like Neptune, Uranus, Jupiter, and Saturn can cause immense tidal heating within their moons, if the moons are close enough. If the moons get too close, they could even turn out like Io! (Extremely volcanically active!) :)

Would you mind giving your thoughts on designing habitable spaces, for research labs, hotels, or experimental zones, what have you, beneath the moon's surface?

[@Anuchan]

Is there any rhyme or reason to the naming if the planetary moons that helps us keep them straight? I know a handful of moons total as to which planet they orbit.

[@LuisAldamiz]

There is some logic: for most planets the moons are named on mythological beings associated to the deity the planet is named after. The exception is Uranus, whose moons are based on Shakespearian characters for some reason. So Triton was a water deity or genie associated to Neptune, god of seas, water, earthqueakes and horses, Io, Europa, etc. were consorts of Jupiter/Zeus, and so on. This works in a Greco-Roman or European cultural context, I guess, it may not work for other cultures with good claims to astronomical discovery on their own right and which give different traditional names to the planets, at least the ones visible to the naked eye. But it's been 500 years of effective Eurocentrism in science, pretty much since Galileo first observed and named the largest four moons of Jupiter (and thought that Saturn had "ears", later found to be rings), so...

Question out of Left Field.......Since Mercury has a core, larger than it should have, is there a possibility that Mercury is the left over remains of Theia???

That's a fascinating idea. But is it even certain there was a Theia?

[@barbaradurfee645]

OK, off to Wikipedia again...I learn so much from these conversations!

[@barbaradurfee645]

Wikipedia: Theia is an hypothesized ancient planet in the early Solar System that, according to the giant-impact hypothesis, collided with the early Earth around 4.5 billion years ago, with some of the resulting ejected debris gathering to form the Moon.[1][2] Theia could explain why Earth's core is larger than expected for a body its size, with Theia's core and mantle fusing with those of Earth. Theia is hypothesized to have been about the size of Mars. Theia may have formed in the outer Solar System and provided much of Earth's water.

[@billkallas1762]

@@NelsonDiscovery Nothing is ever certain except death and taxes.

[@GEOGIRL]

I think Mercury was there before the Moon forming impact occurred. I think the leading thought is Mercury accreted along with the other planets, and I also think the moon is where all the ejected material accreted. If another body formed due to this impact material, it would've likely formed another moon around Earth, I don't think it would've been able to travel so far away and accrete as a separate body with it's own orbit around the sun. (Disclaimer: I am not an astrophysicist, these are just my initial thoughts on that topic, and I could be completely wrong haha) :)

Water is one of the most valuable things you can have in space for a ship or station. You need it for drinking, bathing, flushing, washing other things, some chemical reactions and reductions I suppose and to make oxygen with to go from blue back to pink and also rocket fuel is pretty important but there is one last thing it could be great for and that is to freeze into a ballistic missile to impact an incoming asteroid with and set a powerful explosive in the head of that. A nuclear bomb in a second stage space x space ship size tanker filled with water and allowed to freeze would amplify the impact of the nuclear bomb and the nuke would certainly amplify the impact of the ice bomb.

[@TheWadetube]

There is added value in mining moons with very low gravity and that is how cheap it is to get it into space to use it in ships and stations. Iron here costs pennies per pound but to get a pound of it into space costs around $1,000 dollars so it's painful to just send it up without desperate need for it, but from a moon or asteroid it would cost very little to send up a bundle of steel plating for something. Gold or platinum or Iridium or Ruthenium would be worth mining,.... Rhodium, any of the platinum group metals but most metals besides these are more valuable to keep and use in space and is not cost effective to send down to earth where they are only worth pennies or a few dollars per pound. We need to build a ship yard for building ships and stock it with materials for construction at a cheap price.

Europa is likely I think to have life. Enceladus I think looks too clean. But Triton, this is new. What an amazing thing if it did actually have life. And I bet it has cryofossils around the geysers.

I am actually coming out with a video on how earth got its water next week! ;D It is different than outer solar system planets and moons because during planet formation in the early solar system, all the water was in the outer solar system, whereas the inner solar system was dry, so how Earth got its water is very different from how moons like Triton got their water ;)

@@GEOGIRL How do you know that all the water was in the outer solar system? Is this factual or an evolutionary guess?

[@GEOGIRL]

@@peterclarke3990 Well I'll talk much more about it in the video, but basically the temperature gradient in the early solar system from inner to outer solar system was such that the inner part was super hot due to the heat of the sun's formation, which pushed out all the volatiles, like water and other gases, to the outer solar system (which is why the outer planets are all gas or ice giants). This is factual in the sense that all the physical and thermodynamic models for the early solar system suggest that water or water containing minerals would not have been stable in the inner solar system, but even without these models, it is pretty clear that they are right given that all the inner solar system planets are rocky and the outer ones are gas or ice. :) Again though, it is difficult to go into detail over the comments, so hopefully when it comes out you can check out the full video, I think it will answer a lot of your questions! :) (that said, I am happy to continue to answer your questions over this thread if you have more) :)

@@GEOGIRL Thanks for your reply. Well, I shall look forward to watching the video in due course. Interesting that you base your views on ‘models’ so nothing definite or factual. There may other reasons why the inner planets are rocky and the outer ones much larger and gaseous albeit with a small solid core. After all, gas can’t revolve around itself. It needs a gravitational source to keep it in place just as the rocky planets do to keep the solids from spinning off into space. Suffice to say that your view on origins, and mine, are completely opposite, but I wait to what your new video brings. Take care!

Neptune’s moon Triton is larger than Pluto, Neptune’s second-largest moon is Proteus. But, Proteus is not spherical, it has a deformed crated surface. Proteus is slightly smaller than Saturn’s moon Mimas. Let me explain different facts about different dwarf planets……. 2015 TG 387 - 2015 TG 387 is an extremely trans-Neptunian dwarf planet beyond Pluto, and the Kuiper Belt. TG 387 is nicknamed “the goblin” because of its discovery near Halloween in 2015. It takes “the goblin” dwarf planet 30,000-40,000 years to complete an orbit around the sun. “The goblin” dwarf planet is 300 kilometers in diameter. “The goblin” dwarf planet is 1/3 of the dwarf planet Ceres. “The goblin” dwarf planet is smaller than Saturn’s moons Mimas, and Enceladus. “The goblin dwarf planet is 1/5-1/6 the diameter of Pluto. “The goblin” dwarf planet does not have any known moons. 90377 Sedna - Sedna is an extremely mysterious trans-Neptunian dwarf planet beyond Pluto, and the Kuiper Belt. Sedna was discovered in November of 2003. Sedna was named after the Inuit goddess of the Arctic Ocean. Sedna takes more than 11,400 years to complete an orbit around the sun! Sedna at its aphelion can be 76 astronomical units. Sedna at its furthest point from the sun can be 937 astronomical units away! Sedna is smaller than Pluto in diameter. Sedna is believed to have a red surface similar to Mars. Sedna is smaller than Saturn’s moon Tethys. Sedna will be at its perihelion in 2075-2076. It is believed that Sedna did not originate from the solar system, and that the sun stole it from another solar system. Sedna does not have any known moons. Eris - Eris is the most massive dwarf planet ever found. Eris was discovered in the beginning of January of 2005. Eris was named after the Greek goddess of discord. Eris is believed to be a bit smaller than Pluto. Eris has a quite similar size to the country Russia. Eris at its perihelion can be almost 40 astronomical units away. Eris at its aphelion can be almost 100 astronomical units away. Eris has one known moon called Dysnomia. Eris takes 558 years to complete an orbit around the sun. Eris is the largest dwarf planet not visited by a spacecraft. Ceres - Ceres was discovered in the beginning of 1801. Ceres is the closest dwarf planet to Earth. Ceres is the only dwarf planet that not is trans-Neptunian object. Ceres was named after the Roman goddess of harvest, and grain crops. Ceres is the most massive object in the Asteroid Belt between Mars, and Jupiter. Ceres is smaller than Pluto, Eris, and most other dwarf planets. Ceres contains 1/4-1/3 of the entire mass of the whole Asteroid Belt. Ceres takes some 4, and 1/2 years to complete an orbit around the sun. Ceres is larger than Saturn’s moons Mimas, and Enceladus. Ceres does not have any known moons. Pluto - Pluto is perhaps the most famous, and most known of all the dwarf planets. Pluto was discovered in 1930 by American astronomer Clyde Tombaugh. Pluto was named after the Roman god of the underworld. Pluto was not named after the Disney dog. Pluto was the 9th planet for 76 years. Pluto was removed from the solar system, and was demoted to a dwarf planet because more dwarf planets were being discovered. Pluto is smaller than the earth’s moon. Pluto is also smaller than the country Russia. Pluto takes 248 years to complete an orbit around the sun. Pluto has five known moons, its five moons are called Charon, Nix, Hydra, Styx, and Kerberos. Charon is the largest moon of any dwarf planet. Charon is 1/2 the diameter of Pluto. Pluto will complete an orbit in 2178.

Haha Well remember when we say habitable for life as we know it, we are talking more so on a microbial scale. For a planet or moon to be habtiable for species like humans would be a whole different story! lol We go with habitable for any earth life because we are just looking for life period, not necessarily intelligent life.

​@@GEOGIRL - Yeah, I understand; it was just a joke. It's interesting that, in somewhat recent decades, we expanded the idea of what a "habitable" range could be due to discovering life in extreme places on earth, like at the edges of underwater volcanoes; but more recently, we expand the definition due to new theories or understanding of what conditions likely exist in the more remote planets, as well as what might be possible that could still qualify as "life".
