Did My Star Sign Change? 7 Reasons Ophiuchus Is NOT the New Zodiac Sign

Global panic ensued when NASA first announced that the star signs changed to include a new, 13th zodiac sign called Ophiuchus. But don’t believe the new zodiac sign hype. You’re still the same astrology sign you’ve always been, whether it’s NASA or a TikToker telling you otherwise. Here’s why.

(original publication date: September 2016)

Constellation constipation? The world got its collective knickers in a knot several years ago when NASA published a post claiming that the star signs changed due to the Earth’s wobbling axis and shifting constellations.

Since we first wrote about this phenomenon in 2016, The Wall Street Journal has brought the “new zodiac sign” subject back into the headlines. In the summer of 2020, at the peak of the pandemic, we saw sensational headlines all over the internet about “a new star sign.” In 2024, there would be TikToks abound with the latest version of “your zodiac sign has shifted.” We recommend you enjoy these articles and TikToks for their entertainment value, but don’t buy into the misinformation!

While the world’s skeptics and horoscope-haters and debaters rejoice, astrologers everywhere know it’s all a cosmic crock—there is not a new zodiac sign.

Here are some fast facts you can use to debunk this astrology drama—and reclaim your rightful title as a Leo, Scorpio, or whatever your star sign may be!

1. The constellations have shifted. The zodiac sign dates have not.

Periodically, astronomers will announce “breaking news” that horoscopes aren't accurate because the constellations have shifted. Or they will announce a 13th zodiac sign, citing the constellation Ophiuchus and claiming that the horoscope dates for the zodiac signs have changed.

Here’s an interesting bit of clarification between astronomy and astrology. The actual constellations in relationship to the earth HAVE shifted over the ages. But Western astrology follows a different system called the Tropical Zodiac.

This system uses “artificial” constellations—30-degree segments of a circle that are named after the constellations but not tied to it. The zodiac dates are based on the apparent path of the Sun, called the ecliptic (pictured), as it moves through these 30-degree zones. Rather than following the movement of the visible stars, Western astrology is based on the apparent path of the Sun as seen from our vantage point on earth. Within that path, astrologers have carved out static zones, and we track the planetary movements against these. That is why there are no new zodiac signs—and the zodiac sign dates remain the same even as the heavens keep shifting.

The NASA star sign changes and new astrology signs would be accurate IF Western astrology was still tied to the position of the constellations. But it’s not.

2. There are actually three different branches of astrology, and the star sign dates change depending on which you use.

There are actually 3 “branches” of astrology, and this is also what adds to the confusion about new astrology dates:

  • The Tropical Zodiac—used by Western astrologers—which is based on the seasons and the ecliptic
  • The Sidereal Zodiac—used in Vedic astrology, or Jyotish, and IS tied to the constellations
  • The Constellational Zodiac—a modern invention that includes the star sign Ophiuchus and the supposed new zodiac dates (the NASA zodiac sign dates)

Pro tip: Most astrologers don’t even consider the Constellation Zodiac, which the NASA star signs would fall under, to be accurate or legitimate astrology. So when you hear someone say that the zodiac signs have changed, they are referring to a whole different system...one that would be accurate if it were based on physics and astronomy.
