(225088) 2007 OR10 is a very large planetoid located in the scattered disc. It is the largest known body in the Solar System without a name, approximately the size of Haumea, and appears to be a dwarf planet.

Naming
2007 OR10 was discovered by California Institute of Technology astronomers as part of the PhD thesis of Meg Schwamb, who was at the time a graduate student of Michael E. Brown. Brown nicknamed the object "Snow White " for its presumed white color, as it would have to be very large or very bright to be detected by their survey. It was also the "seventh dwarf" discovered by Brown's team, after Quaoar in 2002, Sedna in 2003, Haumea and Orcus in 2004, and Makemake and Eris in 2005. However, "Snow White" turned out to be one of the reddest objects in the Kuiper belt, comparable only to Quaoar, making the nickname inappropriate.

The naming controversy lasted until 2199 when Astronaut Gibert Grimm said after setting foot on the planetoid. "If Snow White doesn't fit Red Ridinghood will, that place is redder than the face of my father when he was told who my father really was")

While the object is officially called "Oh-Arr-Ten, many locals call it Red Ridinghood.

The settlement established in 2200 named Schwamb Camp has grown into a 8 million inhabitant city.

The planetoid rich in iron ore and magnetide was mined unil 3400. Today it is a vibrant community with a diverse industry still heavy on smelting and producing steel (still an important building material)

However most ore is now imported.

Main Exports: Steel alloys

Main Imports: Ore, Groceries, Tech
