More about planets

The book First Steps to Astronomy and Geography, from 1828, listed the planets as "Mercury, Venus, the Earth, Mars, Vesta, Juno, Ceres, Pallas, Jupiter, Saturn, and Herschel." Apparently the name "Uranus" hadn't caught on yet.

The thing that interests me about that quote is that as far as I know, it was a local maximum for number of planets, since the asteroids were demoted by the time Neptune was discovered. But if the IAU's proposal goes through, we'll beat that list by one, and then add many more in the near future.
