“If 2003 UB313 is a 10th planet, astrologers say it may have a profound influence over people's lives, and thus on the forecasts astrologers make. But its potency cannot be discerned until perhaps several years after the astronomical debate is settled, when astronomers have had time to chart its orbit. So astrologers are not inclined to do anything hasty. There will be no tearing up of charts, no hurriedly penciling in a new planet and certainly no crossing out of Pluto, a body that many astrologers hold near and dear.”
