Be interesting to see what differences there are between a visitor from another solar system and an asteroid from our system.

I think it's an above average astronomy focused channel. In my opinion he does pretty thorough research on the topic of each video. The only question is, how interested are you in the topic. I actually did end up finishing watching that video and I think I learned some more about it.
I've never bought Avi Loeb's theory that it is an alien technological artifact. To me, the Bayesian probabilities weigh heavily in favor of some sort of natural object like an asteroid. I think there are a lot more asteroids and comets in space than there are technological artifacts made by intelligent species, whether terrestrial or extra-terrestrial. Therefore, any new object spotted by a telescope that hasn't been cataloged before is much more likely to be a natural object based on the relative populations of those objects in outer space. The slight anomalies observed here don't amount to sufficient evidence to conclude otherwise.

Which of these videos "triggered" you?
Astrum
How big is the Solar System? What actually orbits our Sun? Why should I even be interested in space? On this channel, we'll answer these and a whole host of other questions. We will have a series dedicated to each of our planets and showcase beautiful images and videos captured by probes and...

Here you go. The difference is zoomed in on the right.

That is in the orbit. But what about its composition? Like what elements and minerals are they made from?

Lead and helium fall at the same rate when only gravity is considered.
Did you watch the video? That might help. Also, consider asking ChatGPT or similar to refine your questions.

Because the person asking is also hallucinating.

None in particular. It's just a general vibe I get when they pop up in my feed. I'd like to have my question answered with something that isn't a question, because I tend not to trust general vibes.

What video are you talking about? This one?
But that one is a picture, not a video. Or are you talking about the one from Astrum? I am not going to watch a 31 minute video whose quality has been questioned.

Questioned for no reason and without evidence.
You can increase the playback speed. Or you can just ask your questions to google if watching a video with all the info packaged in is too demanding.

Actually I did watch Astrum's video after I made the post. It was obvious junk. Discussed if it was a light sail. What rubbish. Just like your post. It did not address my post.

Nothing gets by you.

I don't think anyone knows what elements and minerals Omuamua was made of. We only had a very faint glimpse of it through telescopes. We know that at least one side of it seems to be more reflective than the others. This could because it is oddly shaped. The discussion of whether it might be a light sail was in the context of discussing a hypothesis proposed by Avi Loeb, a Harvard Professor. I agree that this hypothesis is almost certainly rubbish, but I don't think that means we shouldn't discuss it. I think it's worth considering, even just as a thought exercise.

...and absolute crank with the most outlandish theories about extraterrestrials that we've discussed at length in other threads.

The most interesting part of the video to me was not about Oumuamua itself. If it appears to be accelerating somehow... is there anything else like that we've seen? They ask this at about 13:30
They found 6 objects in the solar system that have acceleration that can't be explained by gravity or solar wind. This one kind of looks like it just turns in another direction:

Here is the Wikipedia page on that object:
2006 RH120 - Wikipedia
It is possible that it's something like an old rocket booster according to the article, although there are other possibilities mentioned in the Wikipedia article.
As far as the weird shape of its orbit, that diagram is centered on Earth, not the sun, with the yellow object being the moon, and the earth itself is orbiting the sun. The apparent bend in direction is probably just because it is leaving earth's gravity well.

It's Official: NASA Confirms New Interstellar Object Is Zooming Through Solar System
Astronomers on Wednesday confirmed the discovery of an interstellar object racing through our Solar System – only the third ever spotted, though scientists suspect many more may slip past unnoticed.

I think they misspelled "absolute crackpot".
