ดาวพลูโตในราศีตุลย์: ความหมายและอิทธิพลในแผนภูมิกำเนิด

The sign itself

Libra is a cardinal air sign, and its classical ruler is Venus. The ruler matters in practice: it inherits part of the meaning of this placement, and its own condition in the chart changes how the placement plays out.

Classical standing

Pluto was discovered centuries after the classical dignity table was fixed, so it has no domicile or exaltation in it. The only widely agreed point is the modern attribution: Pluto is linked to Scorpio. The exaltations sometimes handed to it differ from author to author, so we do not quote them.

How rare this is

Pluto takes about 253 years to go around the whole zodiac and stays in one sign for 11 to 32 years. That makes this a generational placement: everyone born inside the window below shares it, so on its own it describes an age group rather than a person. What makes it individual is the house it falls in and the aspects it receives.

When it actually happened

The dates are computed with Swiss Ephemeris, the same engine we use for natal charts. These are the stretches when Pluto was actually in Libra:

• 5 October 1971 - 27 August 1984
• At the edges of these windows the planet crosses the sign boundary back and forth because of retrograde motion, so a birth within a couple of weeks of a boundary has to be checked against the actual chart, not the calendar.
