I am loving all the wonderful insights of my fellow astrologers re the proposed new planets.
Susan Custer has an indepth article here about it all, which includes great links to what others have to say on the subject.
I consider the proposed changes as a reflection of expanding consciousness. Individually and collectively we 'are' the planets, so these 'offical' changes fittingly symbolise an evolution in our understanding about ourselves and our place in the universe.
Here's a link to an expansive online ephemeris to play with that includes the new planets (Ceres, Charon and UB313/Xena), and their positions for any date between 1500 and 2099. Fab!
