Mars is the fourth planet from the Sun orbiting at a distance of 249,228,730km at aphelion and 206,644,545km at perihelion. Mars, the fourth planet from the Sun (after Mercury, Venus and Earth), is the center of interest of the Marspedia project. Of all planets of our solar system, except Earth, it is considered the most habitable place. This makes it the focus for future manned colonization and settlement planning.
