“The expulsion of Pluto would make for a fine new bit of mythological lore. Schoolchildren might feel sorry for Pluto at first, but as they reached adolescence, they’d appreciate his outlaw cachet. He’d be the leader of a disaffected rebel gang — Pluto and the Planetinos, or the Plutonoids, or whatever the coolest rocks from the Sun were called. As new ones were discovered out on the fringes, they could get appropriate names like Hendrix or Cobain.”
