2007 OR10 naming?

• May 11, 2016 2007 OR10: Largest Unnamed World in the Solar System "The names of Pluto-sized bodies each tell a story about the characteristics of their respective objects. In the past, we haven't known enough about 2007 OR10 to give it a name that would do it justice," said Schwamb. "I think we're coming to a point where we can give 2007 OR10 its rightful name."
• Give Dwarf Planet 2007 OR10 the Real Name It Deserves Already 5.12.16
• Dwarf Planet 2007 OR10: Big, Dark, and Slow May 24, 2016
  • Astronomers Megan Schwamb, Michael E. Brown, and David Rabinowitz spotted OR10 in 2007 as part of a search for distant solar-system bodies. They nicknamed it “Snow White,” thinking it was quite a bit smaller and more reflective. Eventually, they’ll have the honor of giving it an official name. “It will no doubt get a name soon,” now that more is known about this mysterious object, says Geert Barentse, “and it might be a name that links back to what we have learned in this study.”

• [14] Jul 17, 2017 Brown "Wow; 10 years since we discovered 2007OR10. I know, I know, everyone wants it to have a name. But could someone get a spectrum for me first?" ... "all three of us are discussing."

• Snow White needs a bailout March 10, 2009

My pick

• Venilia - in Roman mythology, is a deity associated with the winds and the sea. She and Salacia are the paredrae of Neptune. ...she had three children, Turnus, Juturna, and Canens.
  • Should be female to match "snow white", OR10 and Salacia are both low albedo TNOs. And 3 children are available as moons.
