It'd be like 10 to 20 kilometers bigger than Mount Everest.
It'd be a huge piece of rock.
But you know, I think Abby's probably made the wrong bet on that one because as we saw in the in the Hubble image That there's a freaking coma on that thing.
There's no doubt and we've actually imaged it with Hubble Space Telescope James yesterday So it is a comet.
Not completely.
It discredits the idea because his idea was if it's 10 to 20 kilometers in size, that just shouldn't happen.
That's too big by chance for a rock to stray into the solar system that's that big because there just shouldn't be that many big rocks lurking around in deep space.
If it's a smaller comet, there's actually a size estimate now that puts it at a couple of kilometers, I think, as the upper limit.
Yeah, so that makes it, if it's 300 meters across, I mean, it's just a completely normal comet.
Yeah, because you can see this diffuse coma all around it.
So all that stuff.
There's actually, even today, there was a paper on Published.
that detected water coming off it.
Which is what comets do.
They produce OH emission as they fly through.
So we know without any doubt it's a comet at this point.
