: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 [[wp:G V star|G type stars]] like our Sun, along with some F and K type stars. White Dwarfs are by definition [[wp:Spectral classification#White dwarf classifications|D type]]. Unless I'm very much mistaken, any planets in their [[wp:Habitable zone|Goldilocks Zone]] would have been obliterated by the Red Giant preceeding it as its boundaries should be WITHIN the former suface of the Red Giant. Also, Cart'hen III is too small to hold on to an atmosphere, thus also too small for a runaway greenhouse effect ([[wp:Venus|Venus]] style). Without that, to get those temps, it needs to be a LOT closer to its' star. For it to even exist, it would likely be a frozen wasteland, probably far closer in conditions to what Pluto is than to a Hot Desert. There would be no debris from the destroyed planets, they became part of the star, or the [[wp:Planetary nebula|Planetary Nebula]] caused by the loss of its' outer shells when shrinking to a White Dwarf - [[User:Salak|<font color="maroon">Lt.

::For comparison, for the White Dwarf [[wp:IK Pegasi|IK Pegasi B]], the average distance of the Habitable zone works out at around 0.35 AU. - [[User:Salak|<font color="maroon">Lt. Salak</font>]]<sup><i>[[User talk:Salak|Talk]]</i></sup> 05:57, 5 March 2008 (CST)
