The term detriment is used in astrology to refer to the sign of the zodiac that is opposite to a planet’s domicile.
When a planet is in the sign that is opposite to its own domicile, it is said to be in its detriment.
Traditional sources consider a planet being in its detriment to be a debilitating factor.
In traditional astrology, each planet has its detriment in the following signs:
Mars – Taurus and Libra
Venus – Aries and Scorpio
Mercury – Sagittarius and Pisces
Moon – Capricorn
Sun – Aquarius
Jupiter – Gemini and Virgo
Saturn – Cancer and Leo
