Debdeb will be one of the two new star systems in KSP2. Debdeb is likely the name of the star. Debdeb will be the first star system to be added to the game after early access along with interstellar scale parts.
Star and system characteristics
Debdeb appears to be a very young star, estimated to be only 5-50 Myr, and appears more orange than Kerbol. This means it could be a K type star, meaning it would be smaller than Kerbol. It is still young enough to have remnants of the planetary disk now condensed and formed into a planetary debris disk and inner and outer asteroid belts.
If Debdeb is modeled and heavily inspired by Alpha Centauri, it could be assumed that Debdeb is around 3-5 light years away.
The system moves in a circle style configuration with a radius of 0.3 units. The system is offset by -0.5 X axis and -2.5 Z axis units from Kerbol, making it the closest of the other star systems, and roughly analogous in position to Alpha Centauri.
