But it's a weird thing.

I mean, yeah, great, easy to say comet, but...

When it came back around from around the sun, if I'm remembering right, I mean, these are numbers that I'm not horribly invested in remembering, but it was only like 4% water vapor as it came back around.

Comets are dirty snowballs.

They're made of water.

4% water?

Well, now what is this thing?

It's got iron or it's got nickel, but no iron.

Iron and nickel come together.

I mean, they're next to each other on the periodic table.

To separate iron and nickel, you're going to need some difficult processes to separate these two.

And metal meteorites are always iron-nickel meteorites.

Iron and nickel come together.

So now you've got something that's nickel and not iron.

This is a weird thing.

And it suggests some weird processes that went into its formation.

It's got a tail and an anti-tail.

Yeah, there's a lot to worry about here.

And I suspect, I mean, from a practical standpoint...

Clearly, this is something that we don't know much about.
