Every year at the end of November, the Sun leaves the small constellation of Scorpio and enters a much larger one that most horoscopes never mention: Ophiuchus, the Serpent Bearer, the 13th sign of the zodiac. In 2026 the Sun enters Ophiuchus on Monday, November 30, at 05:40 UT and stays there until Friday, December 18, at 13:10 UT. Welcome to Ophiuchus season.

What Is Ophiuchus?
Ophiuchus (pronounced oh-fee-YOO-kus) comes from the Greek Ophiouchos, "the one who holds the serpent". It is one of the 48 constellations listed by Ptolemy in the 2nd century AD and one of the 88 constellations officially recognised by the International Astronomical Union (IAU) today. The figure is a man holding a great snake, the constellation Serpens, which is split into two parts on either side of him: the Head of the Serpent and the Tail of the Serpent.
Ophiuchus lies between Hercules to the north and Scorpio to the south, and its southern part reaches into the Milky Way. Its brightest star is Rasalhague, from the Arabic for "the head of the serpent charmer". The constellation also holds two famous treasures of astronomy: Barnard's Star, one of the closest stars to the Sun, and the place where Kepler's Supernova blazed into view in 1604, the last supernova in our galaxy seen with the naked eye.
Why the Sun Really Passes Through Ophiuchus
The zodiac is the band of constellations that the Sun crosses during the year along its apparent path, the ecliptic. When the IAU fixed the official constellation boundaries in 1930, the ecliptic clearly crossed the southern part of Ophiuchus. The result surprises many people: the Sun spends about 18 days in Ophiuchus, but only about 7 days in Scorpio.
The familiar 12-sign horoscope ignores this for two reasons. First, it divides the sky into twelve equal parts of 30 degrees, while the real constellations have very different sizes. Second, it is tied to the March equinox, which slowly drifts against the stars because of the precession of the Earth's axis, about one degree every 72 years in a cycle of roughly 25,800 years. Over the last two thousand years, the drift has added up to almost a whole sign. That is why the Sun is actually in Libra on October 31, not in Scorpio, and why it reaches Ophiuchus at the end of November.
13-sign astrology simply follows the real sky: thirteen constellations, unequal in length, with the dates the Sun truly enters each one. You can find all thirteen with their dates on our page of 13 signs traits.
Ophiuchus Personality Traits
Ophiuchians are natural investigators. They like to look for the inner causes of things and to explore the details beneath the surface. They are sincere, simple and unpretentious, and when they make a mistake, they repair it with honesty.
The serpent bearer is the healer of the zodiac, and people born under Ophiuchus often fit the role of therapist, counsellor or analyst of difficult situations. They also make inspiring teachers, not by repeating social norms but by sharing their own ground-breaking ideas. At heart, Ophiuchus is the sign of the one who heals his or her mistakes and grows through constant renewal, both mentally and physically.
Their challenges are the other side of the same gifts: a tendency to make situations more complicated than they need to be, and a strong love of independence that can make commitment feel difficult. Read more in our article on Ophiuchus 13.
The Myth of Asclepius, the Healer Among the Stars
In Greek mythology, Ophiuchus is Asclepius, the greatest physician of the ancient world. Son of Apollo, he learned the art of medicine from his father and from the wise centaur Chiron, and he sailed with the Argonauts as their doctor. The serpent he holds was a symbol of wisdom, renewal and healing herbs, and the rod of Asclepius with its coiled snake is still a symbol of medicine today.
Asclepius became so skilled that he could even bring the dead back to life. Hades complained that his kingdom was being emptied, and Zeus struck the healer with a thunderbolt. Apollo, however, made his son immortal by placing him among the stars, where he still holds the serpent high in the night sky. Discover more of the story on our page Ophiuchus, the new zodiac sign.
Did NASA Change the Zodiac?
Ophiuchus makes headlines almost every year. In January 2011, a Minnesota astronomer reminded the public that the Sun passes through Ophiuchus, and the story went around the world. In September 2016 it happened again, after an educational NASA article for children explained that the ancient Babylonians knew of thirteen constellations along the Sun's path but chose twelve to match their twelve-month calendar. Many reports claimed that "NASA changed your zodiac sign".
NASA answered that it had not changed anything: it had simply done the math. And that is exactly the point of 13-sign astrology. Nobody needs to change the sky. The Sun has been passing through Ophiuchus all along, and the 13-sign zodiac simply uses the sky as it really is.
How to Make the Most of Ophiuchus Season
Whatever your sign, the Sun's journey through the Serpent Bearer is a wonderful time for healing, learning and renewal. It favours honest conversations, fresh starts after a mistake, a new course of study, and any kind of care for body and mind. It is also the perfect moment to look a little deeper, as Ophiuchus does, and ask what really lies behind the things you want to change.
