Arbitrary
condensation points for compounds in the formation region. numbers approaching
one indicate a relatively high acquisition rate, where as higher or lower
numbers indicate less abundant compounds.

zone description:
Planetary
conditions: cold extreme life limit
Mean
temperature, K: 234
Life:
indigenous microbial life found deep below surface, palaeo-biological research
indicates surface had more complex surface ecology in the past
Atmosphere:
unbreathable, but an appreciably thick atmosphere, sufficiently cuts down
radiation, and causes a significant increase in temperature by heat capture
(+20'K)
Temperature
at perihelion, K: 236
Temperature
at aphelion, K: 231
