Mr. Martian Mr. Martian is also exceptionally strong, and gifted with the power of teleportation. He uses a Distorter Beam to alter his appearance, and a Multi-Ray to enlarge or shrink his opponents. However, he cannot breathe Earth's atmosphere, and must always wear a protective helmet. Planet Mars was once a paradise, until a nuclear war made the surface uninhabitable. The Martians moved underground, only coming to the surface to use the "Transit Tubes" (which Earth scientists mistook for Martian canals). Under the surface, Martian technology flourished, and continues to do so underneath the planet. Besides being a pastiche of Martian Manhunter,
Stability of the Solar System essentially the distance from sun to earth). These are now known as the Kirkwood gaps. Some asteroids were later discovered to orbit in these gaps, but their orbits are unstable and they will eventually break out of the resonance due to close encounters with a major planet. Another common form of resonance in the Solar System is spin–orbit resonance, where the period of spin (the time it takes the planet or moon to rotate once about its axis) has a simple numerical relationship with its orbital period. An example is our own Moon, which is in a 1:1 spin–orbit resonance
