Tuun System
From Kerbal Space Program Wiki
The Tuun System is a star system that will be in KSP2.
Known Information
Very little is known about Tuun except for its name. The name was discovered in the game's code by u/DartFrogYT, along with the Qeg System.
Properties
The system moves in a figure-eight style configuration. It has a radius of 0.2 units.
Speculation
Though unconfirmed, Tuun and Qeg might be a binary star pair, which would explain why the exploration update on the roadmap only lists one new star system being added.
