Moontanman,
A planet that is the size of Earth has no reason to be in any way more inhabitable than a planet that is twice the size of Earth. Unless you believe that the period of rotation of a larger planet would be insufficient for life due to uneven periods of warmth due to starlight.
However, if it is true that this planet is much too hot to sustain any form of life, then period of rotation or revolution or any other planetary movement or characteristic would obviously be disregarded.
As for you, Janus, I now understand why "fungus" and "mindworms" were referenced.
