The Admin of this Wiki (@User:Ratchetwithclankbot) has estimated or presumed certain Ratchet & Clank details based off of real world bases.
1. Veldin's Population - 20,000 because Veldin's worldly population is about half the size of normal population.
2.Veldin's Political Affiliations - Galactic Democracy, because it is known that in the Polaris Galaxy that Copernicus Leslie Qwark was "voted" in, along with the neighboring galaxy Solana", of the Galactic President Phyronix, therefore it is presumed that it is a Republic/Democracy, simaller to the U.S. and other countries in the Earth.
3. Veldin's p=Medium-Small. Presumed.
