Neptune Opposite Chiron: Longing, Rescue and the Mirror of Others

← Back to Aspects

Neptune opposite Chiron means the two were 172° to 188° apart at birth, on opposite sides of the zodiac within an 8° orb. Neptune is associated with ideals, imagination, compassion and the urge to merge or escape. Chiron, in modern astrology, is a lasting tender spot that can, over time, become a source of insight and care for others. An opposition is often read through relationships: what belongs to one end of the axis tends to be met in other people.

Between 1920 and 2060 the opposition forms only twice, in 1987 to 1991 and in 2048 to 2050, so each is the mark of a few years of births. The houses (when the birth time is known) and any personal planet on the axis show where it is felt.

How it is commonly interpreted

The rescuer and the rescued. A frequent reading is a pull toward saving others, or toward hoping to be saved, with the sore spot and the longing showing up in different people.

Ideals tested in relationships. Astrologers often describe disappointment when a partner, teacher or community cannot live up to an idealised picture, and growth from seeing people as they are.

Seeing the wound in someone else first. Some readings suggest that one's own sensitivity becomes recognisable by noticing it in others.

Compassion with clear edges. The developmental direction commonly named is care that does not require losing oneself.

These are tendencies, not outcomes. The rest of the chart, and the person's choices, shape how the axis works.

Two oppositions, one each side of the 2010 meeting

In the 51,501 daily Greenwich noon charts from 1920 to 2060, Neptune opposite Chiron appears on 1,351 dates: 2.62%, the rarest Neptune-Chiron line in the range. On 11.5% of them the pair is out of sign.

Each stretch has one main window with all three passes: 12 May 1989 to 27 July 1990 (442 dates) and 26 October 2048 to 27 November 2049 (398 dates). Around them come shorter windows where the angle reached orb and slipped out again; the closest, from 30 June 1988 to 20 January 1989, came within 0.40°.

The opposition marks the far point of the cycle that runs from the 1945 conjunction to the 2010 one. It took about 44 years to get from the 1945 meeting to the 1989 opposition and only about 20 to get back to conjunction in 2010, because Chiron was slow for much of the first half and fast for much of the second.

Never retrograde together

Not one opposition date in the sample has both Neptune and Chiron retrograde. Neptune alone was retrograde on 43.2% of opposition dates, Chiron alone on 36.8%, and neither on 20.1%. The reason is the Sun. Neptune is retrograde only when the Sun is about 100° or more from it (the smallest distance in the sample was 99.7°), and Chiron only when the Sun is about 100.4° or more from it. When the two are about 180° apart, the Sun's distances to them add up to roughly 180°, so it cannot be 100° from both at once. In the planet table, an opposition shows at most one R marker.

1989 and 1990: Capricorn and Cancer

The first stretch came while Saturn, Uranus and Neptune were all in Capricorn, and on 301 of the 464 dates in 1988 and 1989 with Saturn conjunct Neptune, Chiron opposed Neptune too. At London noon:

• 18 July 1989: Neptune 10°35' Capricorn, retrograde, Chiron 10°32' Cancer (0.04°). Saturn at 9°28' Capricorn, retrograde, was conjunct Neptune (1.12°) and opposite Chiron (1.08°), and Pluto at 12°22' Scorpio sextiled Neptune (1.78°) and trined Chiron (1.82°).
• 18 January 1990: Neptune 12°40' Capricorn, Chiron 12°39' Cancer, retrograde (0.02°), with Mercury, Saturn and Uranus in Capricorn all opposite Chiron within 6°.
• 26 May 1990: Neptune 14°10' Capricorn, retrograde, Chiron 14°08' Cancer (0.03°), and Jupiter at 11°41' Cancer was conjunct Chiron (2.45°) and opposite Neptune (2.48°).

Capricorn is ruled by Saturn and Cancer by the Moon. Neptune in Capricorn covers this generation.

2048 and 2049, calculated ahead

The second opposition is calculated with the same ephemeris. Exact passes at London noon fall on 14 December 2048 (Neptune 21°39' Taurus, retrograde, Chiron 21°35' Scorpio), 22 May 2049 (Neptune 23°52' Taurus, Chiron 23°52' Scorpio, retrograde, with Saturn at 27°11' Capricorn trine Neptune and sextile Chiron, both 3.3°) and 5 October 2049 (Neptune 25°46' Taurus, retrograde, Chiron 25°48' Scorpio, with Mercury, Mars and Saturn all trine Neptune and sextile Chiron). Taurus is ruled by Venus. Scorpio has Pluto as its modern ruler and Mars as its traditional ruler. See Neptune in Taurus.

Finding it on your chart

On the free birth chart an opposition is a dashed red line across the wheel between ♆ and ⚷; a solid red line is a square. In the planet table the longitudes should be 172° to 188° apart. Births before 1920 or after 2060 have no Chiron on the chart, so the line is not drawn for them.

With no birth time entered, both are placed at local noon as an internal reference, not as an assumed time of birth. Their separation moved by at most 0.18° a day, so the hour could make a difference on only about 0.7% of opposition dates (estimated by interpolating between noon charts). How to read Chiron in your chart suggests where an axis like this fits in a reading.
