As the article explains, if you bring back Pluto you must include Eris too, and perhaps Makemake and Haumea if you ignore is not as round as expected, and who know how many other undiscovered small object near them. (And Ceres? I like Ceres.)
Anyway, 9 is not an option, you must choose 8 or 10+.
I'm on board with all the dwarf planets. MVEMCJSUNPHME should be easy to make a mnemonic.
no you don't. just because some nerds say it doesn't make it true. just bring back pluto and nothing else
Pluto is grandfathered in through the collective Consciousness of society. Just treat it the same way as tomatoes, which are officially fruits but no child believes that crap.
