If you were born under a rotten zodiac sign, you may be in luck. Or you might be out of it.

When astronomers in 2006 declared that Pluto was no longer a planet, the world gasped — and then obeyed. School textbooks were re-written, and scientific discovery ruled the day.

Then this week, a Minnesota astronomy professor took on something even more sacred — our horoscopes.

The astrological calendar was all wrong, he said in public comments that set the Internet aflame.

People might think they’re a Pisces (compassionate, imaginative), but often they’re really an Aquarius (witty, clever) — at least based on an exact reading of the earth’s orbit.

Or maybe, if you were born between Nov. 29 and Dec. 17, you’re actually a strange new zodiac sign: Ophiuchus, the serpent holder.

But who wants to admit to being that snake-guy sign on a first date?

For what it’s worth, I am still a Virgo, and I occasionally check out my horoscope in the paper for the incredibly general advice it offers such as “Don’t date sailors.” As Edith Bunker once noted, “It’s fun to see what’s gonna happen to you even if you know it ain’t true.”
