Which stars make up Leo?
Leo is one of the few constellations that looks like what it’s named for. A backwards question mark of stars, the Sickle, forms the lion’s head and mane, and a triangle behind it makes the haunches and tail.
At the bottom of the Sickle sits Regulus, the lion’s heart. It sits almost exactly on the Sun’s path, so the Moon and planets pass close by it regularly, and sometimes in front of it.
Where does Leo come from?
The Babylonians knew this figure as UR.GU.LA, the Great Lion, and the lion has stayed a lion ever since. Its brightest star had a royal name in almost every language. Ptolemy called it Basiliskos, “little king”, and Copernicus translated that into the Latin Regulus.
Greek myth made it the Nemean Lion, whose hide no weapon could pierce. Heracles strangled it with his bare hands as the first of his twelve labours and wore its skin as armour for the rest of his life.
Every November, Earth passes through a stream of dust left by a comet, and meteors seem to fly out of the lion’s mane. In 1833 that shower, the Leonids, became a storm of tens of thousands of meteors an hour across North America. The panic and wonder it caused helped turn meteors into a science.
c. 1000 BCE

Seasons, not stars
Leo is measured from the equinox and holds the height of northern summer. The lion's stars now host the Sun from mid August to mid September.
How does Leo line up with the real sky?
There are three different versions of every sign. The Earth’s axis wobbles like a slowing spinning top, a full circle about every 25,800 years, and that drags the spring equinox west against the stars by about one degree every 72 years.

Dates of the Sun's passage in 2026, computed by Hali.
Western astrology stays locked to the seasons, Vedic astrology follows the stars, and the two are now 24.2° apart. Hali uses the tropical zodiac because it follows the seasons the signs were named for.
Does science support astrology?
Not as a way to predict personality or events, and controlled studies have found no such effect. We get the sky exactly right and treat the meaning as a language for reflection. Read more in Is astrology scientific?
