Dwarf Planets

In 2006, after the discover of a “tenth planet”, the International Astronomical Union decided to rewiev the concept of planet. According to the resolution, Pluto has been downgraded to the rank of Dwarf Planet, along with Ceres, Eris, Makemake and Haumea. From 200 to 2000 dwarf planets are expected to be found outside Neptune’s orbit. In my story, a dwarf planet threatens Earth [3]. In search for a name, I found “Nestis” (from a fragment of Empedocles), alleged nickname of Persephone, Queen of the Dead, or Iron Queen, according to Odysseus.
