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,
Solar System with many close-in planets, and that typically a sequence of their collisions causes consolidation of mass into few larger planets, but in case of the Solar System the collisions caused their destruction and ejection. The orbits of Solar System planets are nearly circular. Compared to other systems, they have smaller orbital eccentricity. Although there are attempts to explain it partly with a bias in the radial-velocity detection method and partly with long interactions of a quite high number of planets, the exact causes remain undetermined. This section is a sampling of Solar System bodies, selected for size and quality of
