1. We have absolutely no idea where it came from
2. We don't really know what it looks like
...tumbling through space and appears to be, more or less, cigar-shaped.... about 10 times longer than its width.
..object's brightness (or amount of reflected sunlight) varied by a factor of 10 every eight hours or so. This strongly implies that 'Oumuamua has an extremely elongated shape.
3. 'Oumuamua got a little speed boost as it approached us
Observations from the Hubble Space Telescope and ground-based observatories noticed that its acceleration increased which slightly changed its course from what was initially predicted.
“Our high-precision measurements of Oumuamua’s position revealed that there was something affecting its motion other than the gravitational forces of the Sun and planets,"
"This additional subtle force on ‘Oumuamua likely is caused by jets of gaseous material expelled from its surface. This same kind of outgassing affects the motion of many ..."
4. It's the first interstellar object we've managed to observe
5. We don't really know what it's made of
...some scientists have considered classifying the object as an asteroid. But, as described above, it may have kicked off some dust particles and/or gases, giving rise to a small speed boost at some point during its approach.
We do know that it is highly reflective. Especially given its relatively small size.
When compared to other solar system-type asteroids 'Oumuamua is at least ten times more reflective.
6. It's not going to stay around
7. It shows we are not really prepared for future Earth impacts
Its apparent near-Earth trajectory was also something of a worry. Whilst we've 'gotten away with this one', if it had hit Earth, it would have easily erased an entire city.

Who gave it that idiotic name?
“4. It’s the first interstellar object we’ve managed to observe”
Seriously? Really?
There is something being left out of that statement that would make it true.
In a universe of unfathomable size and age anything is possible.
“Who gave it that idiotic name?”
—
Maybe the guy who discovered it, when he first saw it, said “Ooooh, Mama!!!” and it stuck?
“...orbiting within our solar system”. (Which may or may not be true.)
8) it had a twin on a different course and further away.
An astronomer saw it and said “Oh mama!”
The lab writers for the observatory gave it a weird spelling.
I thought it looked Hawaiian and I was right. Scroll down to "Nomenclature."

Seriously? I would like to know more about that.
All these mysteries will be clarified when the alpha predator who sent them arrives ...
Help me out here.
Wrestler or football player?
Seriously? Really?

Other than gas clouds illuminated by stars and black holes, which are only "observable" by their gravitational influence and occasional gravity waves. I suppose he should have said "discrete object not gravitationally bound to a particular star". It certainly appears to be gravitationally bound to the Milky Way. There are stars that are not. Of those stars about 6/7's have been ejected by interaction with other stars, and one-seventh appear to be intergalactic visitors.
It's a real-time analog of 'last days' confusion.
Some of the oddest things about obama, other than his name.
1. We have absolutely no idea where it came from. He says Hawaii. We know Kenya.
2. We don’t really know what it’s like. The media gave us a false image of him.
5. We don’t really know what it’s made of. Certainly not human.
6. It’s not going to stay around. Unfortunately, it stayed around too long.
7. It shows we were not really prepared for an America-hating muzzy-loving marxist.
Much too small.
