On the National Geographic website, there’s an article about poor Pluto being found less rotund than Eris:
“The beleaguered former planet has been dwarfed again by a new study that finds its neighbor Eris is significantly bigger.
That makes Erisâ€”formerly known as 2003 UB313 and then Xenaâ€”the largest so-called dwarf planet in the solar system.”
So, the big winner here is Eris. I mean, in an article about Eris, she’s the largest dwarf. How much more Erisian can you get than being officially a competitive contradiction?
Hail Eris! Kallisti!
