Leo

In astrological tradition

In astrology, Leo is traditionally associated with confidence, generosity, and a warm, expressive presence. Astrologers often describe it as drawn to creativity and recognition, though these meanings are interpretive rather than scientifically established.

Element and modality

Leo is a fire sign and a fixed sign, a combination astrologers traditionally read as steady, radiant, and self-assured. It is the only sign traditionally ruled by the Sun.

Where the figure came from

The lion is one of the most stable identifications in the zodiac. Babylonian sources call the constellation UR.GU.LA, the Lion, and the figure passes into Greek tradition essentially unchanged, where it is identified with the Nemean Lion killed by Heracles in the first of his labours.

The constellation, and how it differs from the sign

Leo is one of the few zodiac constellations that genuinely resembles its figure. The Sickle — a backwards question mark of stars — outlines the lion's head and mane, with Regulus at its base, and a triangle to the east marks the hindquarters. Regulus lies almost exactly on the ecliptic, so the Moon and planets pass very close to it and occasionally occult it.

The distinction matters and is easy to lose. The sign is one of twelve exactly equal 30-degree divisions of the ecliptic, measured from the March equinox in the Western tropical system. The constellation is an IAU sky region with irregular boundaries fixed in 1930, and the twelve zodiacal ones differ enormously in the span of ecliptic they cover. Precession has separated the two by roughly one sign over the past two thousand years.

A royal star, and the Leonids

Regulus was one of the four stars Persian astronomy treated as royal, marking the approximate positions of the equinoxes and solstices around three thousand years ago — alongside Aldebaran, Antares and Fomalhaut. Precession has moved all four off those markers since.

The Leonid meteor shower radiates from within the constellation each November. Its parent is comet Tempel–Tuttle, and because the debris is unevenly distributed along the orbit, the Leonids have produced some of the most intense meteor storms on record as well as many unremarkable years.
