I'll correct my edit comment. I read "radius", not "diameter" for some reason. Cart'hen II's a lot smaller than [[wp:Pluto|Pluto]] and [[wp:Eris (dwarf planet)|Eris]], is probably more comparable in size to [[wp:Charon (moon)|Charon]] or [[wp:50000 Quaoar|Quaoar]] which are both Dwarf Planet candidates. The former is currently considered Pluto's largest moon. | I'll correct my edit comment. I read "radius", not "diameter" for some reason.

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/ | The rereading also brings Cart'hen III into doubt.

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. Salak</font>]] (Amateur Astronomer)<sup><i>[[User talk:Salak|Talk]]</i></sup> 04:21, 4 March 2008 (CST) | ||
