And their images often go into public archives.

And you can look through them if you

really want to dig through all the data, and people are.

Because like I said, Planet 9 and this Earth mass planet or Mars mass planet are all reasonably bright.

So they've probably been imaged if they're out there.

It's just we didn't note them as moving objects.

So maybe they'll get pulled out of the archival data.

But I know that it's going to be really exciting.

And I would be super surprised if we don't get some seriously planetary mass objects out there, because there's so much space left to be surveyed in the outer solar system.

So thank you.

Oh, him?

So there was a spike in 1962?

A very big spike.

Let's pull that up.

I don't know my asteroid history as well.

Yes.

So that is actually how we get some of our best size estimates for the larger Kuiper Belt objects.

And that's actually how we know how big MU69, that tiny, tiny target is.

Because we're sending a spacecraft to it, they actually deployed telescopes.

They knew there was an occultation shadow last year, and they sent out people to get five or six occultation cords across the object to measure its size.
