Default Sedna can't be a planet.

Sedna can't be a planet because the planets are named after Roman
gods. Sedna is named after an Inuit one, therefore it isn't a planet.

But we already know Earth isn't a planet- it's the only one that doesn't wander!

I had thought that myself, but in fact, it is a planet, spanning 180
degrees (more or less), making one circuit around the celestial sphere
in just one sidereal day (by definition). Therefore, not only is it a
planet, but it is the fastest moving one, and the only one on which we
can see inhabitants.
