Very interesting, and it gives a really good highlight of the whole Oumuamua event, which got a bit distorted in the media.

The things that stood out were:

- Our range of vision to spot such objects is narrow;

- We don't have much "resolution" of the object, and we have to work with limited data;

- that fact that we managed to get that data was already really good and it's enough to theorize about a lot of stuff, but not enough to tell precisely what it was.

- the object behavior as it approached the sun doesn't match the type of object that we perceived at the beginning;

- the object could have been stationary;

Having watched the vid, he goes into specifics of why he thinks Oumuamua is 'not a rock' based on geometry and reflectivity. It was quite fascinating.

Fantastic episode.
