Sun in Leo

The Sun in Leo is associated with warmth, confidence and a generous, creative spirit. The Sun rules Leo, so traditional astrology counts it as at home here, and modern astrologers read it as a person who wants to shine and to make others shine too.

What the Sun stands for

In a birth chart the Sun is the center of the self: will, vitality and the sense of purpose a person grows into. Ancient astrologers counted it as one of the two lights, with the Moon, and read it for life force and standing in the world.

Modern astrology puts the Sun sign first because it is the one placement anyone can work out from a birthday. That popularity began with Alan Leo around 1900 and the newspaper horoscope columns of the 1930s. The Sun is still only one part of a chart, and it reads best alongside the Moon and the rising sign.

How astrologers read it

Leo is the Sun's own sign, and a Leo Sun is usually described as the placement at its most natural: open, expressive and proud in the best sense. People with it often gravitate toward the stage in some form, whether that means performing, teaching or leading a team.

Astrologers stress the heart here as much as the ego. A Leo Sun tends to be fiercely loyal and generous with praise, and it is often happiest when making something of its own.

In relationships

A Leo Sun in love is described as warm, affectionate and generous with gestures. It wants to be admired by the person it loves, and it tends to return that admiration in full.

Strengths and shadows

At its best this placement is brave, playful and big-hearted. At its worst it needs too much recognition, takes criticism personally, and has trouble sharing the spotlight.
