...Sedna’s placement in the natal chart is not so much a mystery as a revelation of a new aspect of ourselves which each of us as individuals must now learn to integrate into our conscious being: the caretaker of humanity and this planet.
...Then ka-boom. Sedna arrives. A 10,500-year orbit? How in the world does that fit into this nice little schema of inner and outer planets? Short answer: Sedna doesn’t. Sedna represents a new category of planet, a third category which hasn’t been officially named by the astrological community. However, my third house Moon in Aries demands a label, so for the purposes of our discussion here I’m going call Sedna the first of the Great Year planets .
Here’s why. The Great Year is defined by the precession of the equinoxes, and the precessed cycle is some 25,770 years long by current scientific calculations. Geophysically precession is simply the slow wobble of the Earth’s axis, and it gives us the 12 ages of the zodiac, the Age of Aquarius and the Age of Pisces being the most current and most famous.
The Mayan calendar, tied inextricably to Mayan cosmology and its attendant astrological system, neatly defines the demarcation point for the ending and beginning of a Great Year as that time when the Sun, the ecliptic, and the centre of the galaxy are conjunct. That only happens once every 25,770 years, and December, 2012 is the next occurrence. The centre of the galaxy, now around 27 degrees Sagittarius, was considered a sacred spot by the Mayans, the place from with God emerges, to very crudely translate their complex cosmology. These days we know the centre of our galaxy, and most galaxies for that matter, to be a black hole, an intriguing phenomenon which likely is also a dimensional gap into the metaphysical planes.
