After reading the rules on gravity and atmosphere on pages 331 and 333, I started thinking about the rest of the Solar System beyond some of the examples given.
"Worlds with lower than 0.7 G are considered low-gravity worlds while those of 1.3 G or above are classed as high gravity. On both low and high-G worlds, characters will have trouble moving around and get a -2 modification to all AGILITY, CLOSE COMBAT and STAMINA tests. After a period of acclimation, this modification disappears."
Following this guidance, the only places in the Solar System that are high gravity are the Sun and Jupiter and the only other places that aren't low gravity are Neptune, Saturn, Earth, Venus, and Uranus, right? Is there anywhere in the Solar System where the toxic atmosphere rules would come into play instead of the vacuum rules on page 107?
