• Ceres - The largest asteroid to have ever been discovered by humanity.
• Eris - Currently the largest Dwarf Planet known. It is almost 10% larger than Pluto in diameter.

Many years later in 2006, scientists debated over if it was really big enough to actually be considered a planet, and after much talk, it was declassified. The Pluto Slipstream Monitoring Station Democritus is stationed in orbit around it. On November 3, 2552, the Monitoring Station detected Cortana's signal in Slipspace with Dr. Halsey's message to Lord Hood.
