A planet with an identity crisis, Class Q worlds are referred to by Star Charts as “variable.” These are planets that are generally unstable. They may be located in a star system’s hot zone, ecosphere, or cold zone and have surface conditions that can range from extremely hot to extremely cold, even on the same planet. Class Q planets may be found in eccentric orbits creating climactic swings that subject the surface to molten lava or frigid ice. The atmosphere of the planets may also vary wildly from very thin to very thick.
