Regulus

The heart of the Lion and its move into Virgo

Regulus is Alpha Leonis, magnitude 1.4, the bright star at the heart of the Lion. In the tropical zodiac it stood at 29°08′ Leo in 1950, 29°50′ Leo in 2000 and 0°11′ Virgo in 2025. It crossed from Leo into Virgo around 2011–2012. The cause is precession: the equinox from which the signs are measured drifts backwards against the stars, so every star advances about 1° in 72 years.

The birth year therefore changes both the degree and the sign. With a 1° orb, someone born in 1950 has a planet on Regulus between 28°08′ Leo and 0°08′ Virgo. For someone born in 2025 the window runs from 29°11′ Leo to 1°11′ Virgo. Older charts meet the Lion's heart in Leo; younger ones increasingly find it in the first degree of Virgo.

Regulus lies only 0.46° from the ecliptic, closer than any other first-rank star, so the Sun passes almost directly over it each year and the Moon often covers it. A zodiac conjunction here is a real meeting in the sky. Ptolemy, in Tetrabiblos I.9, says the star on the Lion's heart is like Mars and Jupiter.

The king star

The star's names keep returning to kingship. Babylonian astronomers called it the King, Ptolemy wrote of it as Basiliskos, the little king, and Copernicus gave the Latin form Regulus. It sits at the heart of Leo, the lion Greek myth identified with the Nemean beast whose hide no weapon could pierce and which Heracles strangled with his hands.

The lion is courage and rule, and the heart is the seat of both. The story of the Nemean lion also carries a warning that fits the star's later reputation: the strongest creature of its age was overcome, and its pelt became another hero's armour.

Mars and Jupiter, and the royal-star tradition

Ptolemy's Mars and Jupiter nature joins courage with honour and generosity. Medieval authors treated Regulus as one of the most powerful stars for rank and success, and Vivian Robson in 1923 kept that reputation while repeating the warning attached to it: honour that rises high can be lost, and success can end in ruin.

Regulus is also counted as a royal star of Persia, the Watcher of the North, with Aldebaran, Antares and Fomalhaut. That scheme is a later tradition. European writers from the late eighteenth century onward attributed it to Persia, noting that around 3000 BCE the four stars lay near the equinoxes and solstices, but the ancient source is thin. A modern saying ties Regulus's gifts to one condition, avoiding revenge, and astrologers often use it as shorthand for the star's warning.

Read today, Regulus describes authority and a big heart. It suits people who lead, and it asks them to lead without grievance. The move into Virgo is often read as the king learning to serve, the Lion's pride joined to Virgo's care for detail and usefulness.

Regulus conjunct a planet

The Sun reaches Regulus around 22–23 August, at the turn from Leo to Virgo. People born then carry a Sun on the Lion's heart and often show ambition, warmth and a wish to be at the centre of something worthwhile. For recent birth years this Sun is in Virgo, and the leadership tends to be practical.

The Moon on Regulus gives emotional pride and generosity, along with a strong need to feel respected. Old slights can sting for a long time; letting them go is the star's own advice.

Mercury here gives commanding speech and confidence in one's ideas. Venus brings a generous, dramatic style in love and a wish to be admired. Mars on Regulus strengthens courage and leadership and needs a cause worth fighting for. Jupiter matches the star's nature and is read as honour, patronage and success. Saturn tempers the rise and often delays recognition, which can make it more durable. Uranus, Neptune and Pluto describe a generation's relationship with power more than a single life.

Regulus on the Ascendant or Midheaven

Regulus rising gives a dignified, confident manner, and people tend to treat you as someone in charge. That can open doors early. The tradition's caution is pride: the presence works best with humour and generosity.

On the Midheaven Regulus is one of the classic indicators of high position and public honour. It suits leadership, management and any role where others follow your lead. Astrologers add the star's warning here more than anywhere: recognition that comes fast is easier to keep when you do not use it to settle scores.
