StarTalk Radio
Secrets of Asteroid Bennu with Harold Connolly Jr.

Pushed material up, which was not commentary-like, but we had looked, going back to the comment discussion, we had looked for commentary action because one of the hypotheses for Bennu before we got there was it could have been an extinct comet core.

But it isn't.

StarTalk Radio
Secrets of Asteroid Bennu with Harold Connolly Jr.

At least most of us will say it isn't.

StarTalk Radio
Secrets of Asteroid Bennu with Harold Connolly Jr.

No, sir.

StarTalk Radio
Secrets of Asteroid Bennu with Harold Connolly Jr.

No, sir.

StarTalk Radio
Secrets of Asteroid Bennu with Harold Connolly Jr.

It is not.

StarTalk Radio
Secrets of Asteroid Bennu with Harold Connolly Jr.

You know that better than I. Yep, it is not.

StarTalk Radio
Secrets of Asteroid Bennu with Harold Connolly Jr.

Right.

StarTalk Radio

So let's go back to, again, the square root of one, and that phosphorus is, of course, one of the elements on a periodic table, as you said.

StarTalk Radio
Secrets of Asteroid Bennu with Harold Connolly Jr.

And the accretion time period of the asteroid, you have all this material accreting, which contains all the different elements that we have on a table, you know, to...

some extent not things like hydrogen and helium and stuff um then as time goes on minerals start to form through the interaction of water with these rocks that we talked about and that water is moving through with different what i call nutrients in this case it's not for biological system but geologic system and things like sodium like in sodium chloride table salt and chlorine and phosphorus are in this fluid and then i love that reference to geologic nutrients that's a cool that's a cool thought

I was hard when I was in high school.

StarTalk Radio
Secrets of Asteroid Bennu with Harold Connolly Jr.

Let me just say that.

StarTalk Radio
Secrets of Asteroid Bennu with Harold Connolly Jr.

I was a geek.

StarTalk Radio
Secrets of Asteroid Bennu with Harold Connolly Jr.

Anyway.

StarTalk Radio
Secrets of Asteroid Bennu with Harold Connolly Jr.

Yeah, so there's a whole sequence that forms of these different minerals, the calcium-rich ones, then the phosphorus-rich ones, right?

StarTalk Radio
Secrets of Asteroid Bennu with Harold Connolly Jr.

And they go down through what's left in the fluid to come out of the fluid and start forming new minerals.

StarTalk Radio
Secrets of Asteroid Bennu with Harold Connolly Jr.

You get things like sodium, et cetera.

StarTalk Radio
Secrets of Asteroid Bennu with Harold Connolly Jr.

And phosphorus is one of those key minerals that makes things like phosphates.

StarTalk Radio
Secrets of Asteroid Bennu with Harold Connolly Jr.

And of course, phosphorus is one of the key kind of elements that gets bound together with things like carbon and hydrogen, et cetera, to form prebiotic compounds that are important.
