doing astronomy homework:

"One reason astronomers object to astrology is that it has no link to the physical world. For example, precession has moved the constellations so that they no longer match the zodiacal signs. Whatever sign you were "born under," the sun was probably in the previous zodiacal constellation. In fact, if you were born on or between November 30 and December 17, the sun was passing through a corner of the nonzodiacal sign.*"

((following the asterisk, you can find this at the bottom of the page))

"*The author of this book was born on December 14 and thus has no astrological sign. An astronomer friend claims that the author must therefore have no personality."
