Why Ophiuchus appears in news stories
The Sun does pass through the constellation Ophiuchus, inside its official boundaries, so any date list built on constellations has to include it. That's where the "13th sign" headlines come from.
Why astrology still has twelve signs
The tropical zodiac is a mathematical division of the ecliptic into twelve equal sections anchored to the equinoxes and solstices.
Does Ophiuchus change your sign?
Not in the standard tropical zodiac. It only changes your answer if you switch to a different system, such as one based on constellations.
