	The rereading also brings Cart'hen III into doubt. A diameter of 4378km puts that planet in the same ball park as [[wp:Callisto (moon)\|Callisto]] (Jupiters' second largest moon) and [[wp:Mercury (planet)\|Mercury]], both have diameters in the 4800-4900km range. Density lacks a unit of measurement, but assuming it is g/cm<sup>3</sup>, that makes it more dense than any of the [[wp:Terrestrial planet\|terrestrial planets]] in our solar system (all under 5.6). Surface gravity can be calculated using other stats using a formula found at [[wp:List of Solar System objects by surface gravity\|List of Solar System objects by surface gravity]]. I've not tried checking that one myself. - [[User:Salak\|<font color="maroon">Lt.

			:Oh, and you'll be doing amazingly well to find a habitable planet around a White Dwarf. Earth like planets are only thiought possible around G type stars like our Sun, along with some F and K type stars. Whute Dwarfs are by definition D type. Any planets in their Goldilocks Zone (Not too cold, not too warm, just right for life) would have been obliterated by the Red Giant preceeding it. - [[User:Salak\|<font color="maroon">Lt.
