Scorpio: Dates, Meaning, and the Scorpion Explained

The scorpion zodiac sign — its dates, symbol, mythology, and why it's one of the few constellations that actually looks like its name.

Scorpio is the eighth sign of the zodiac, covering October 23 through November 21. Its symbol is a scorpion, and Scorpius (the constellation's formal name) is unusual among zodiac constellations for actually resembling what it's supposed to be — a long, curving line of stars with a distinct hooked tail, anchored by the reddish star Antares at its heart.

Scorpio dates and basic facts

• Dates: October 23 – November 21
• Symbol: The Scorpion (Scorpius)
• Element: Water
• Modality: Fixed
• Ruling planet: Pluto (modern), Mars (traditional)
• Brightest star: Antares, magnitude ~1.09 — a red supergiant whose name means "rival of Mars," a reference to its rusty color

Where the scorpion symbol comes from — and why it hates Orion

In Greek myth, the scorpion was sent — depending on the version, by Gaia or by Artemis — to kill the hunter Orion after he boasted he could hunt down any creature on Earth. The scorpion succeeded, stinging Orion to death, and both were placed in the sky afterward. But they were placed on opposite sides of the celestial sphere, so that as one rises, the other sets — meaning Orion and Scorpius are never visible in the night sky at the same time, a detail ancient skywatchers built directly into the myth as ongoing enmity.

What Scorpio is said to represent

As a fixed water sign ruled by Mars and Pluto, Scorpio is traditionally associated with intensity, emotional depth, and a strong instinct for privacy — deeply loyal to whoever earns its trust, and just as capable of holding a grudge against whoever breaks it. The pairing of a water sign's emotional undercurrent with Mars's sharp edge is usually cited as the source of Scorpio's reputation: not aggressive on the surface, but formidable once provoked.

Why Scorpio is easy to find in the night sky

Between Antares's brightness and a shape that genuinely curves like a scorpion's tail, Scorpius is one of the most recognizable and faithfully-shaped constellations in the zodiac — a rare case where the ancient figure and the actual star pattern line up closely, rather than requiring real imagination to connect.
