You know what time it is. It's time for Ask a Space Man. I'm your host, Paul Sutter. You've got questions, and I've got the answers. Pretty simple idea. You know how the show works, but I'm going to let you know

anyway because maybe it's been a while, you know? All right. So you go online to Twitter or Facebook,

use the hashtag ask us, spaceman. Do what the hashtag suggests and ask a spaceman. You can also

send me questions directly on Facebook and Twitter. You can find me at Paul Matt Sutter because that's my name.

Kind of weird if I were to use someone else's name.

That'd be a little bit complicated.

So I used my own.

I used my own name for my Twitter handle.

Seem to make sense.

You can also go to askus spaceman.com.

And we have a very simple goal with this show. Very straightforward.

Complete knowledge of time and space. It'll take a while, but I don't plan on going anywhere

anytime soon. So don't you worry. Now on that road to complete knowledge of time and space,

we have a bunch of questions.

I've been getting questions in past few months, especially with like the news of exoplanets in general.

And some specific questions like John Ziegler on Facebook, he asked, well, actually he started out just saying exoplanets, exclamation point.

I feel the same way. Just everyone say it. Exoplanets. That's so much fun. His actual question was,

how reliable are the measurements? And what's up with orbital migration and hot Jupiters?

Dan Cataldo on email, he was also curious about planetary migration,

asking how it works. At Infirmus on Twitter said, has Kepler, this is one of the planet hunting

missions that we have, been giving us false positives when it comes to exoplanet detection?

Mark on Twitter at Mark Reeb asked of all the exoplanets discovered how many correspond to the planets around our own sun, like how weird are they?
