not the 11th planet
Mark Whittington proposes naming the Kuiper Belt Object 2003EL61 as Persephone. He also calls it a planet, even though it is only 1/3 the mass of Pluto. Too bad it is probably too small to be considered a planet, and also too bad that there is already an asteroid named Persephone.
Update: Mark changed the link in his post; as I suspected, he meant to point to an article about 2003UB313. However, he still wants to call it Persephone.
