In 2267, geophysical findings of the rogue planet Gothos indicated that the surface had no detectable soil or vegetation, the temperature was extremely hot, it had a toxic atmosphere which was swept by tornadic storms, continuous volcanic eruptions, and deadly to any lifeform as the crew knew it without oxygen and life support systems. The estimated survival time of two unprotected individuals was not very long.
