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.

Have you heard about the bird?
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 wont run out of money in retirement.
I like the way you think.

If most star systems are binaries, how does that make this weirder?
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.
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.
...
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?
LOL
” systems with two close-orbiting stars boot out asteroids much more efficiently than one-star systems do. “
Well when you turn 18 million years old, you get kicked out of the solar system house.
