Topocentric Part of Fortune Birth Chart Calculator

This calculator uses topocentric coordinate system and the Part of Fortune.

The topocentric system calculates planetary positions relative to the observer's location on Earth's surface, rather than from Earth's center (geocentric). This results in slightly different positions, particularly for the Moon, and is preferred by some astrologers for its physical accuracy.

The Part of Fortune is a calculated Arabic Part that represents worldly success, prosperity, and where we can find joy. It is calculated from the positions of the Sun, Moon, and Ascendant. This calculator displays the Part of Fortune alongside the traditional planets.
