The following is a conversation with Custin Teen Batigian, Planetary Astrophysicist at Caltech,

0:06.6

interested in, among other things, the search for the distant, the mysterious Planet 9,

0:13.1

in the outer regions of our solar system.

0:16.0

Quick mention of our sponsors, Squarespace, Literati, Onit, and N.I.

0:25.1

As a side note, let me say that our little sun is orbited by not just a few planets

0:30.0

This to me is amazing.
