The Moon in the Birth Chart. The Moon is a very important planet in the Birth Chart as it is from this that we operate from through childhood and thus it becomes our foundation. Although we grow towards our Sun (our own 'mind') in adulthood, the Moon is a 'feeling, reflective' energy that picks up and stores early messages and experiences. Many of our behavioural and emotional problems can be uncovered by examining the role of Moon in the Natal Chart. The Moon informs and represents the way we habitually respond and react throughout life. It denotes our instinctive behaviour and the sign it is in describes its innate quality, whereas the house reflects the environmental influence. Any aspect to the Moon shows how it reacts. If for example it has a connection to Mars, then it may be more assertive in having its needs met. Moon with Venus will emphasise its female or creative quality and Moon in aspect to Mercury may be able to express its feeling in some communicative way..
Comets are really traveling relic icy planetesimals, the remnants of what was once a vast population of ancient objects that contributed to the construction of the quartet of giant, gaseous planets of the outer Solar System: Jupiter, Saturn, Uranus, and Neptune. Alternatively, the asteroids--that primarily inhabit the region between Mars and Jupiter termed the Main Asteroid Belt--are the leftover rocky and metallic planetesimals that bumped into one another and then merged together to form the four rocky and metallic inner planets: Mercury, Venus, Earth, and Mars. Planetesimals of both the rocky and icy kind blasted into one another in the cosmic "shooting gallery" that was our young Solar System. These colliding objects also merged together to create ever larger and larger bodies--from pebble size, to boulder size, to mountain size--and, finally, to planet size.
A moon is a natural body that is in orbit around a planet, and it is kept in place by both the host planet's gravity and the gravity of the moon itself. Some planets possess orbiting moons; some do not. There are several theories explaining how Earth's Moon came to be. At this point, the favored model is termed the giant impact theory, often playfully called the Big Whack or Big Splash theory by astronomers when they are in a humorous frame of mind. These funny nicknames were derived from the central tenet of the theory, which is that a Mars-sized body, named Theia, smacked into the primordial Earth billions of years ago. The collision caused part of our planet's crust to be hurled violently into space. Some of this shattered, somersaulting debris was snared into Earth-orbit, where it formed a host of moonlets that were ultimately pulled together by gravity to evolve into our Moon.
