I don’t think there’s any indication that it’s spinning.
Incorrect. There are strong indications.

I was looking at pictures of it's path through our solar system and it looks so odd to me where it entered and as it passed our Sun it began to change it's acceleration and took like a 90 degree turn! Weird.
Almost like a comet. The Sun's gravity tends to do that.

That link says that the turning was estimated, not observed.

“Rotation period estimates are inconsistent and varied.”

“No single rotation period can explain the exhibited brightness variations. Rather, 1I/‘Oumuamua appears to be in an excited rotational state undergoing non-principal axis rotation, or tumbling.”

I’m not convinced. If the idea of turning is only based on brightness variations then it could be actual lights on the object. Or the light of propulsion, maybe.

Am I missing something about it?

Is this the correct path?

How can the sun make it switch directions that hard and sudden?

Doesnt look very natural or cometlike to me. Just checked out some recent comets' paths in our solar system and there's nothing even similar.

Is that the correct path tho?

And you said that you didn't think there was any indication that it is tumbling. There is strong indication that it is doing so.

But the indication is only brightness variations, right?

I’m skeptical that that indicates turning, necessarily.

Especially it seems nonsense that the simulations always show it tumbling end-over-end.

How about the thing flies straight and remains level, while rotating the other way?

Hard and sudden? No. It's a clean parabolic curve (hyperbolic, actually, but close enough).

Why "recent?" Have you checked out comets which pass as near the Sun? Try Halley's comet, for example. Or 96P/Machholz 1.

I think he was talking about the seeming vertical drop in the line in the illustration. I’m guessing that’s just how they draw it?

Ah. He's talking about the "stalks?" Right, that's not the orbit. Just indicators of where it was relative to the ecliptic.


Its path is drawn in magenta before its October 19, 2017 discovery, and then in yellow. Stalks connect it to the ecliptic plane, that is the Earth-sun plane, at the beginning of each month.

It's too bad we didn't see it coming earlier. We could have dropped a probe on it to ride out of the solar system.

I don't think we have anything that could have caught it, even if we found it earlier.

the most interesting thing about the Inter-stellar object to me

is that it was aptly named ::



An interstellar asteroid has received a name that’s fitting to its status: ‘Oumuamua (“Oh-moo-ah-moo-ah”), a Hawaiian word meaning “a messenger from afar arriving first.”

The first-of-its-kind object forced the International Astronomical Union to come up with a new system for designating small bodies that apparently come from beyond the solar system.



MPC designation: 1I/2017 U1 … aka: Oumuamua


A new paper titled, "The origin of interstellar asteroidal objects like 1I/2017 U1," which is still under review, takes a look at three possible origins for `Oumuamua'

We conclude that ’Oumuamua is part of the left-over debris of the star and planet formation process in the Galaxy. We expect that the Galaxy is rich in such objects, with a density of ∼ 10 14 or 10 15 objects per cubic parsec. We estimate the probability that a s ̄ olus lapis passes the Sun within 1 au, taking the gravitational focusing corrected cross-section into account, at an event rate of about 2–12 per year.

Interesting. Not very rare but this is the first one we've seen? They don't seem to address that.

It would certainly be an interesting engineering challenge.

You can't just build a Vogon hyperspace bypass without first taking a few measurements.

Yes the Dyson sphere laser must be linked to the crafts power remotely to increase light speed captain

Somehow, Oumuamua reminds me the book "Rendez-vous with Rama".

Do yourself a favor, stop using the ridiculous or whatever civilization rating system. It's a not particularly funny joke that pretty directly contradicts everything we know so far about actual civilization and technological advancement!

Seriously, it's pure weapons grade derp of the highest order and when otherwise smart people try to sound smarter by using this ridiculous scale... They just look stupid.


are you but Hurt ! against your Religion ?

Looking Stupid , you must be in the We are the only ones in the Galaxy that is the Highest Civilization.


and I do what I want... So Keep on having those eyes Closed , and Those fingers in Your Ears.!
keep on Trolling away .. let the negativity run through ..

so are you calling Miko Kaku Stupid ?


The Physics of Extraterrestrial Civilizations
How advanced could they possibly be?

New Developments Since Kardashev gave the original ranking of civilizations, there have been many scientific developments which refine and extend his original analysis, such as recent developments in nanotechnology, biotechnology, quantum physics, etc.
