As time passed, the region would have cooled down considerably and contracted--thus pulling away from its surroundings and forming fractures akin to the cracks that form in mud as it becomes dry--but on a considerably larger scale.
The moon plays a large role in astrology and astrological phenomena. The position and phase of the moon influences the other aspects of astrology, including sun signs and planetary movements. In fact, the moon influences other aspects of astrology as a whole.
Most of the moons of our Sun's family circle the quartet of large gaseous planets located in our Solar System's outer limits: Jupiter, Saturn, Uranus and Neptune. The four solid inner planets--Mercury, Venus, Earth and Mars--are almost entirely moonless. Earth is the only inner planet that hosts a large Moon, while Mars sports only a pathetic duo of misshapen little Moons (Phobos and Deimos), that are either captured asteroids that escaped from the Main Asteroid Belt between Mars and Jupiter, or are instead the outcome of a primordial collision between Mars and a large protoplanet.
