I recently finished reading two books that had Pluto in them (one had a little, one had a lot).
When is a Planet Not a Planet?: The Story of Pluto felt like an article that had been stretched into a small book by using lots of photos and illustrations. A pretty book, but it didn’t have anything new in it for me (to be fair to the book, I spent a big chunk of time in graduate school writing a paper about Pluto’s so-called demotion).
The Three Stigmata of Palmer Eldritch is supposed to be one of Philip K. Dick’s best books, so I was curious to read it. For Pluto, it’s just mentioned as a place where a ship crash lands. For the rest of the book, it was like the other things I’ve read by him—it had a lot of sci-fi elements but was really about people’s perceptions of their world. Weird and interesting.
To round out the Pluto references, my daughter started pre-school recently and I was fascinated to see that the teachers had crossed Pluto out of the solar system material they had (wanting to stay up to date, but not getting around to buying a new planet puzzle yet).
It’s a really interesting time right now—the change in status is new enough that a lot of old information is still out there, but it’s been long enough that younger kids have grown up only knowing that Pluto used to be a planet. It’s a paradigm shift in action with the new generation simply accepting the new status as normal while any disagreements among older generations start to fade away.
