Check a planet’s position
Use a tropical zodiac position from a chart or ephemeris. Choose day or night according to whether the Sun was above or below the local horizon in the chart. The lookup stays in this browser and does not require a birth record.
Select a planet, zodiac degree, and day or night, then calculate.
What this lookup includes
It reports the sign’s domicile ruler, exaltation ruler, sect-dependent triplicity ruler, and the Egyptian bound ruler at the exact degree. The last ruler changes at irregular degree boundaries. Ptolemy records these categories in Tetrabiblos Book I; the displayed Egyptian bound table is his transmitted common table rather than his separate reconstructed bounds.
The result also flags a planet across from its domicile or exaltation. These are traditional detriment and fall relationships. This lookup does not turn the categories into a personality score or a prediction. Different authors use different bound and triplicity tables; compare the method and full twelve-sign table before reading a result.
