1st Known Interstellar Visitor Gets Weirder: 'Oumuamua Likely Had 2 Stars

Our solar system's first known interstellar visitor is likely even more alien than previously imagined, a new study suggests.

The mysterious, needle-shaped object 'Oumuamua, which was spotted zooming through Earth's neighborhood last October, probably originated in a two-star system, according to the study.

'Oumuamua means "scout" in Hawaiian; the object was discovered by researchers using the Panoramic Survey Telescope and Rapid Response System (Pan-STARRS), at Haleakala Observatory on the island of Maui.

...

"It's really odd that the first object we would see from outside our system would be an asteroid, because a comet would be a lot easier to spot, and the solar system ejects many more comets than asteroids," study lead author Alan Jackson, a postdoctoral researcher at the Centre for Planetary Sciences at the University of Toronto Scarborough, said in a statement.

But 'Oumuamua probably didn't come from a system like our own, according to the new study. Jackson and his colleagues performed computer-modeling work, which indicated that systems with two close-orbiting stars boot out asteroids much more efficiently than one-star systems do.

And there are a lot of these binary systems out there; previous research has suggested that more than half of all Milky Way stars have close stellar companions.

it is indeed an alien invader, what with a name sooooo very, very similar to Obummer’s

“Jackson and his colleagues performed computer-modeling work, which indicated that systems with two close-orbiting stars boot out asteroids much more efficiently than one-star systems do.”

I bet their computer models also proved that global warming played a part in this.

Once again, our brightest scientists have created a computer model that explains how the universe works. I wonder if they could also create a model to tell me where to invest so I won’t run out of money in retirement.

I like the way you think.

If most star systems are binaries, how does that make this weirder?

Which means that, one-star systems ALSO eject objects.

So, we really don't know where yo-mauma came from.

Then, if an object gets "strategically" placed between 2 large objects, like Jupiter and the Sun, the object can be sent careening out of a one-star system too.

So, the computer model is lacking in "diversity" of scenarios.

Well, it’s kind of obvious that a central “point-like” object cannot gravitationally expel so much as a grain of sand. ( N. B. a grain of sand and an asteroid are in the same category here. )

But with a spinning pair of suns ... let your imagination run wild.

...

So it’s not weird as the title says.

” ‘Oumuamua Likely Had 2 Stars”

Is that like “Heather Has Two Mommies?”

Sounds like they are stretching what little they know about this object until the data screams for mercy.

Funny, I don’t much trust “experts” any more. Wonder why?

Well when you turn 18 million years old, you get kicked out of the solar system house.
