Sedna, the 10th Planet
Most distant object in solar system found. The name is tenatively Sedna, after an Inuit goddess. (Which I think is not the right name. Keep it in the same pathos as the others for goodness sake.)
The only real question is “What makes a planet?” It’s tiny (1,000 miles across), but so is Pluto (1,500 miles across). No atmosphere.
Be interesting to see.
