Ovin
From Kerbal Space Program Wiki
Ovin is an exoplanet in KSP 2. It has rings and its surface gravity is four times that of Kerbin. Ovin has no tall mountains, and it may be close to its star. It is 60% larger than Kerbin. It appears to have an atmosphere, although that is merely speculation and may not be the case. It is theorized to be in the unknown Second Star System, but this is unconfirmed.
It will be in KSP 2.
