An hour and 27 minutes...

Can you sum up in a sentence or two, please?

[Jamestown1630]

It’s basically a humorous but interesting summary of his book by the same name, including how his discovery of the largest trans-Neptunian object, Eris, resulted in ‘killing Pluto’ in terms of planet status . From his Amazon biography:

“He specializes in the discovery and study of bodies at the edge of the solar system. Among his numerous scientific accomplishments, he is best known for his discovery of Eris, the largest object found in the solar system in 150 years, and the object which led to the debate and eventual demotion of Pluto from a real planet to a dwarf planet.”
