Part of Fortune — Astrology glossary

The Part of Fortune is an Arabic Part, a calculated point rather than a planet, found by combining the positions of the Sun, Moon, and Ascendant. Its formula differs for day and night births. In a natal chart it marks an area where ease, flow, and a sense of natural reward tend to gather, where effort meets less friction than elsewhere. It matters because it adds a note of where a person finds things working out without forcing them. For example, the Part of Fortune in the tenth house can suggest that public roles and career bring a settled, fortunate quality. Astrologers treat it as a supporting point that refines a reading rather than a headline feature of the chart.
