Betelgeuse
Betelgeuse is the great red star that marks the right shoulder of Orion, the hunter, diagonally across the figure from blue-white Rigel. It is a red supergiant, one of the largest stars visible to the eye, and its brightness rises and falls over months; in 2019 and 2020 it dimmed so markedly that it made the news. In astrology it is read as a star of martial success: bold, competitive achievement and the recognition that follows it.
In the zodiac
Betelgeuse stands at about 29° Gemini today, in the last degree of the sign, and will cross into Cancer in the coming decades. It moves forward about one degree every 72 years through precession, so a chart from 1950 places it about a degree earlier, near 28° Gemini.
Its nature
Ptolemy gives the stars on Orion's shoulders the nature of Mars and Mercury. The tradition said Betelgeuse brought fortune, martial honours and lasting distinction, and it was counted among the most favourable of the bright stars.
Modern astrologers usually read it as drive joined to quick wits: courage, a competitive spirit, and the skill to act decisively when it counts. It tends to favour those who take the initiative, in sport, leadership or any field where nerve is rewarded, and the honour it promises is usually the kind that is earned in the open.
In a chart
A planet within about a degree or a degree and a half of Betelgeuse tends to take on its boldness. With the Sun or Mars it can describe a person who rises through courage and effort; with Mercury, a sharp, decisive mind; on the Midheaven, recognition for achievement. The star colours the point it touches rather than acting alone, and works through that planet's own sign, house and aspects.
