LiWelcome to Terra Productions where I make comics and animations who also made their own sound effect.
Kerbin is in the Kerbolar System with Kerbol as it's star
These are the planets in the Kerbolar system:
Moho Eve Kerbin Duna Dres Jool and Eeloo
it WAS a user submitted sprite but I forgot to add it.
If you are asking where I based it off of, I based it off of the planet from Kerbal Space Program.
