back to article 'Weird' OBJECT, PROPELLED by its OWN JETS, spotted beyond Mars orbit by Hubble

A bizarre spinning object, described by NASA as "weird and freakish" and shooting jets of matter that cause it to move, has been spotted in our Solar System. The mysterious rock, located in the asteroid belt between Mars and Jupiter, was seen spewing matter from its surface by the Hubble space telescope on September 10. Then …

    YORP? Really? Naming something that terribly could only be the result of a women's health product focus group, or alien conspirators who have infiltrated the astronomy field in an attempt to cover up the imminent arrival of more landing craft if, as in this case, they were accidentally spotted. Even the lamest Human astrophysicist could come up with something better than "it's like, spinning man, really fast and parts are flying off". The fact this kind of stuff is printed in the media is just proof that they're in on it too.

    Erm...

    "The prevailing theory now is that the asteroid is being spun around so quickly that it is breaking apart under the strain of its own rotation. "

    Wouldn't this create a spiral effect like the arms of our galaxy, rather than the straight-line ejecta the photos show?

    1. Wzrd1

      Re: Erm...

      Possibly.

      I'm more thinking it got spun by an impact that fractured the asteroid, permitting sunlight to warm volatiles beneath the surface that normally would not have been heated.

      I'd go take pictures and gather samples, but some Doctor stole my transportation...

    2. MrMur

      Re: Erm...

      Surely, the outpouring is also travelling in the direction of the spin at the point it left the influence of the object itself? So a spiral effect could be reduced to a point of being not visible to the naked eye?

      Just guessing. Might be bollocks.

    3. FrozenFlame

      Re: Erm...

      I read it as the sun would make the object rotate fast and faster until it started to break apart under it's own centrifugal force, at which point, the gas would be released from the asteroid in the form of jets thus causing the propulsion seen. It would then not be spinning as it was originally due to the sudden propulsion in one direction.

    First example?

    "Since the pressure from the Sun is constant, and space is virtually frictionless, then asteroids can spin faster and faster until they disintegrate."

    Given that the number of asteroids is in the millions, that they have been around for millions of years, and that the effect is something that should have been going on for quite a while for, probably, a considerable portion of those asteroids, is the fact that this is the first observation of the effect an indication of lack of attention up to this point?

    1. TechnicalBen Silver badge

      Re: First example?

      No idea if it's a fault of the article... but some unequal force is needed for spin. So something would need to be set up just right for this one rock to spin from solar forces only. I'd put such a theory below "hit by another rock" and "off-gassing of ice under the surface (thus the sudden event and surface having no ice) on the plausibility scale. But then which one get's more funding/headlines/papers published? The plausible one, or the crackpot... ahem, less likely and more convoluted explanation?

      1. NoiTall

        Re: First example?

        My vote is on 'hit by another rock'. It's hard to explain that the basically constant solar radiation across the rock's surface would impart rotation. But maybe that's just the journalist's lack of understanding that lead to the omission of that essential explanation. As it comes without the article is next to useless, other than bringing an odd object into the broader public news arena.

        1. marioaieie

          Re: First example?

          Actually you explain with the assimetry of the asteroid, as it was hinted in the article...

          "This YORP effect (named after the four scientists who contributed to the theory: Yarkovsky, O'Keefe, Radzievskii, and Paddack) has been suggested as a reason for the relative paucity of small, asymmetrical objects within our Solar System in comparison to rounder rocks, and the search is now on for more observations of the theory in action."

          1. TechnicalBen Silver badge

            Re: First example?

            Again, that's the theory, as yet without observation. Do uneven shapes rotate when solar radiation is applied? Or show that the sun "burns off the edges and makes them round" as the above quote seems to suggest.

            Many other factors can play to why the rocks are round (structure, strength, gravity, impact) etc.

            I'll not quote the astronomer, physicist and mathematician on a train gag. ;)

            But I'm not suggesting it's wrong, just it's still very low in the plausibility until more observations are made. :)

            1. Tom_

              Re: First example?

              The force coming from the sun hits the sunward facing side of the asteroid fairly evenly. So if the asteroid is asymettrical, there will be a greater force to one side of its centre of mass than the other. This will cause it to spin.

      2. Lapun Mankimasta

        Oh for pity's sakes Re: First example?

        Everything in space spins to some degree. Angular momentum is universal. It's more a question of how much this asteroid's angular momentum differs from other asteroids'. And it's likely that the outgassing is the result of a thin layer of insulating rock being eroded off by flares and the like, than an impact.

        1. TechnicalBen Silver badge

          Re: Oh for pity's sakes First example?

          Lapun Mankimasta, the question is, how does the sun impart rotational momentum. I do not question that it exists for objects orbiting the sun. The question is, how is an energy gradient setup so that the rock gains momentum in it's rotation?

          As for the wind/pin wheel. Yep, that's down to the shape. So, have they observed the shape of this rock to confirm it? It's the difference between claiming "rocks spin because of solar wind" and "rocks spin because of collisions with other rocks".

          As said, it's no doubt a correct theory, but it needs observation to support it first.

      Yeah I saw that, but did/if you look on in further at Haumea's orbit, it may be a gravitational slingshot away from coming to inner solar system, this inter galactic pool is trickier than appears, it seems they might not need the probe, I seen "when worlds collide", so it must be true ...

  11. BestofAndy

    Spinning so much that the innards of the asteroid are coming out of the core through the several crater holes that it has, and giving a garden sprinkler like effect. The real question is: how can a massive crater get so much angular momentum that is spins wildly enough to have its innards spewing out? This does not make much sense. Perhaps its a aliens version of a Mexican fireworks, or pin wheel?

    The Asteroid is Electrically Charged and Passing Through the Sun's Electric Field

    The asteroid is approaching the sun and thus moving further into the sun's electric field (which accelerates the solar wind away from the sun). The asteroid has an electric charge and thus behaves like a comet - check this out : The Electric Comet at https://www.youtube.com/watch?v=34wtt2EUToo

      Care to explain how the asteroid can keep its charge for any amount of time at all? Being immersed in solar wind which is rich in charged particles of all sort would then equalize its charge to pretty much exactly zero faster than the European Central Bank deciding on another half-percentage cut of the interbank interest rate.

    170 degrees K to hot for ice

    "One idea was that we were seeing ice on the asteroid outgassing, but the object is too hot, around 170 Kelvin, for ice," he explained.

    To hot for ice? I must admit that it has been a very long time since I studied this but at a -103.15 degree C does not seem to hot to me.

      Re: 170 degrees K to hot for ice

      Blame that semi-explanation, i.e. NO explanation, on the journalist who merely repeated the line without wondering what it meant. But, this might help: Space is mostly a very large volume that nearly everywhere has a truly dazzling vacuum, much emptier than anything we can create on Earth. That next-to-nothing pressure implies that (water-) ice would be sublimating (solid turning into vapor) at a very low temperature. However, the ice is likely maintained well above the equilibrium temperature for the local "vapor pressure" by the substrate \ rock it is attached to, which receives thermal radiation, may be radioactive itself, etc.

    Gravitational Instability

    Planetesimal Formation by Gravitational Instability:

    The growing understanding of planetesimal formation is that it occurs by gravitational instability, explaining their spherical contours; however, excess angular momentum often causes them to fragment as they gravitationally collapse, forming gravitationally-bound binary comets, asteroids and trans-Neptunian objects (TNOs). And perturbed binaries may frequently spiral in to merge and form peanut-shaped 'contact binaries'.

    An alternative hypothesis suggests that gravitationally-collapsing stars may form bar-mode instabilities which become isolated pairs of giant planets when the protostar collapses to form a core, abandoning its two 'bar-mode' arms. If the arms are gravitationally bound within their own Roche spheres, they may go on to gravitationally collapse to form proto-planets.

    And giant proto-planets may go on to fragment (bifurcate) due to excess angular momentum, forming binary planets. Then the energy and angular momentum of their binary orbits cause them to spiral out from their progenitor stars until their binary components spiral in and merge, forming solitary planets.

    Moons may similarly spin off from gravitationally-collapsing proto-planets during their own bar-mode instability phase, forming moons that bifurcate and spiral out from their progenitor planets. Saturn's moon Iapetus may be a contact binary without sufficient gravity to form a completely spherical surface, hence its contact-binary walnut-shape and the raised ridge around its equator.

    the rotation theory does not seem to fit what's show in the image. besides, why would the fact that it is rotating cause it to heat up over a hundred degrees more than its surroundings?

    it's far more likely to be the result of residual heat from a collision. there could have been radioactive material in the asteroid that ignited in the collision.
