Deb Deb
Deb Deb will be one of the two new star system in KSP2 Deb Deb is likely the name of the star. Deb Deb will be the first star system to be added to the game after early access along with interstellar scale parts.
Planets
So far the only planets confirmed to be orbiting Deb Deb from inner to outer, Char, Gurdamma, and Glumo, but possibly also including the Rask-Rusk binary system, and Puff. The other shown planets, Lapat and Ovin, seem to be in a different system.
Star and system characteristics
Deb Deb 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 likely 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 modeled and heavily inspired by alpha centauri it could be assumed that Deb Deb is around 3-5 light years away.
