Gliese-631 (also known as Ayseta) is a rare solar system with a rather plentiful amount of planets and a brown dwarf in the outskirts. 2 large dwarf planets exist with an extremely elongated orbit, usually coming in between d and c (also called Izio and Vantia by some). The system's counterparts has been given names by the community. (Note: I created this on a ROBLOX game called SolarSim. This was automatic, and I simply recorded results and gave names.
Gliese-631 d ("Izio")
This was the last planet to attain planetary status.
