Planet 8

From Sedes Draconis

The eighth planet in the Solar System is unnamed. It orbits Lêl at a distance (semi-major axis) of 19.6 AUs. It is a small gas giant with a mean radius of 23,800 km.

The unnamed eighth planet is visible to (some) naked eyes from Sânat under many circumstances, but it is very dim, and moves in the sky very slowly. It has not been noticed as a wanderer or of any other significance.
