Neptune May Have Eaten a Planet and Stolen Its Moon

jitendraharlalka noted a piece about the origins of Neptune. There is a theory now that it once ate a super-earth in the outer solar system, and kept its moon as some sort of macabre trophy to make sure that Mars and Venus didn't get any big ideas.

      It is well known that the Earth's core is liquid and made almost entirely of iron. It has been shown that rotating a mass of liquid metal generates a significant magnetic field. It's where Earth's field comes from. Mars also has an iron core, but it is solid all the way through, which explains the lack of a magnetic field.

      With no magnetic field Mars gets no filter - it gets the full blast of the Sun's radiation, which pretty much destroys any chance of life at the surface. Without the magnetic field to re-direct some of the Sun's rays, more of Mars's atmosphere also gets launched into space.

      Ugh. Every time one of these stories comes up, someone has to bring up Velikovsky. As someone who studies early solar system evolution, I've had the "pleasure" of talking with Velikovsky supporters on numerous occasions. What Velikovsky wrote about was wide-scale rearrangements of the architecture solar system WITHIN HISTORICAL TIMES, based on nutty interpretations of classical mythology. What the article here discusses is a hypothesis for the formation of Triton during an event called the Nice model that is thought to have happened about 3.9 billion years ago (based on dating of large lunar basins from Apollo samples). During this time, a much more massive precursor to the Kuiper belt fueled the migration of the outer four giant planets, disrupting stable reservoirs of small bodies throughout the solar system. Once the ancient Kuiper belt was depleted of mass, the migration stopped (so the "fuel" is gone, and therefore this process can only occur once in the lifetime of the solar system). Had planetary migration occurred within historical times, then we would currently be in the midst of a massive bombardment of comets and asteroids, and the Earth's oceans would currently reside in the atmosphere (along with perhaps some rock vapor clouds). The Nice model and Late Heavy Bombardment is backed up by observations of the structure of the Kuiper belt, observations of other solar systems around other stars, radioisotope dating of lunar rocks (in a variety of isotope systems, but most especially K-Ar, and U-Pb), observations of the structure of the asteroid belt, dynamical models based on plausible initial conditions for the early solar system (constrained by aforementioned observations), observations of zircon crystals found in ancient Earth rocks, cratering chronologies of the rocky planets, the Moon, and icy satellites. Basically it's a preponderance of evidence pointing toward plausible models for the early history of the solar system. Velikovsky has tortured interpretations of ancient literature. Who do you think is more likely to be closer to describing reality?

  27. Some orbital dynamics by Michael+Woodhams · · Score: 5, Interesting

    Some may wonder what need there is for a third body at all - Triton wanders too close to Neptune, it gets captured, right?

    The reason is conservation of energy: as Triton wanders near Neptune, it falls into Neptune's gravity well and accelerates, so it is going too fast to remain in orbit. Triton at infinity has more energy than Triton in orbit, so to get captured it has to lose energy, and that energy has to go somewhere.

    With a few exceptions, three body interactions (e.g. Neptune, Superearth, Triton) are chaotic, and often end with one of the bodies being expelled and the remaining two left in orbit. The lightest body is the most likely to be expelled. This scenario has Superearth being expelled rather than Triton, which is somewhat unlikely but not impossible. (It is too long since I studied this for me to quantify 'most likely to be expelled'.)

    It really doesn't seem to me that you need Superearth to explain Triton. The third body could very easily have been a normal Neptunian moon, which is now unobserved somewhere in the Oort cloud or expelled from the solar system entirely. (Could it be Pluto? This was thought of and rejected a long time ago.)

      The reason we invoked the extra planet was that in these three-body encounters, it's much more likely that the more massive object gets ejected and the smaller captured. However, the surveys of the Kuiper Belt are such that if Triton had larger twin, we'd have found it by now. But noone has, so a different capture method remains plausible. The existence of the extra planet isn't actually the hard part to prove, but rather that it impacted instead of being tossed by Neptune down to Saturn or Jupiter, who could then throw it out of the solar system.

      "...it's much more likely that the more massive object gets ejected and the smaller captured."

      How does this work? My memory from a few lectures 20 years ago is the opposite, but clearly you're more reliable than I am. I thought it was an equipartition of energy thing - interactions will tend to divide the energy evenly between the objects, which means the lightest is the most likely to acquire escape velocity. Is it that ejecting the lightest object doesn't usually take away enough energy to leave the other two bound?

      If you're trying to drop Superearth into Neptune, then it has to both get very low angular momentum and at the same time high energy (else Triton would not be bound to Neptune). This seems a very narrow target to hit. If you're arguing relative probabilities (it is more likely that the more massive object gets ejected) then you need to establish that the unlikelihood of impact is outweighed by the gain in likelihood of losing the larger rather than smaller object.

      It had not occurred to me that the disappearance of the third body could be a two stage process: ejected from Neptune orbit, then secondarily ejected from the solar system by Saturn or Jupiter. What are the odds that an object ejected from Neptune orbit will eventually be ejected from the solar system? My gut feeling is that the odds are pretty good, that falling into a resonance with one of the giant planets or being ejected are the only long term options. (Where 'long term' I'd guess to be thousands or millions of years, not billions.)

      Whether absorbed or ejected, this interaction with Superearth would tend to increase Neptune's orbit's eccentricity. How does the expected increase in eccentricity compare to the current eccentricity of Neptune's orbit?

      My counter hypothesis is that the third body was a pre-existing but now lost Neptunian moon. Now that I think on it, equally plausible is that Triton was this original moon (originally in a regular prograde orbit) and an outside object came in, formed a 3 body system for a while, and then was ejected.

    3. Re:Some orbital dynamics by simonbp · · Score: 5, Informative

      what happens in these binary captures is that you have two objects orbiting around each other and falling at essentially escape velocity towards Neptune. If it were just one object, it would either hit Neptune or zoom past and leave Neptune's sphere of influence. But since there are two objects, one is going slightly faster than escape velocity, and the other slightly slower. If there is no collision, then one that is going slower can be captured, while the other is ejected from the system. If the two objects are not of equal mass, then the smaller is going to be moving faster than the larger, and thus there is much wider window of opportunity for it to be captured. So, it's not impossible for the larger to be captured, just much less likely.

      In the case of a collision, it is more like likely that the larger will impact, as the center of mass is closer to it, and impacts are the merging of centers of mass. In this case, we think that Triton would be in a sufficiently wide orbit that it would watch the impact from a distance, and then either ejected (if its orbital velocity was in the impact direction) or captured (if its orbital velocity was in the opposite direction). So, Amphtrite could have had multiple moons, but Triton was the one on the correct quarter of the orbital phase to be captured.

      Thanks - that all makes sense.

      I was thinking in terms of more elaborate interactions where the bodies do multiple 'orbits' before one is eventually ejected, rather than a single pass. That is why all my instincts were going astray.

      (My encounter with three body systems was in the context of binary+single star meet in a globular cluster. As I recall, if the binary is loosely bound, they tend to dance for a while before ejecting the lightest star. If the binary is tightly bound, it tends to get more tightly bound and eject the single star with greater energy. This is a source of 'heating' in globular clusters.)
