Free Nessus Asteroid Calculator
Enter your birth details to find centaur 7066 Nessus: a pattern-naming prompt by sign and house, read as cycles available for interruption rather than verdicts on character.
What Nessus is, and what this calculator returns
Nessus is centaur 7066, discovered on April 26, 1993 by the Spacewatch survey. It orbits between Saturn and Pluto, completes one circuit of the zodiac roughly every 122 years, and shows up in modern asteroid astrology as a prompt for cyclical patterns of harm and the point at which those patterns become interruptible.
The calculator above returns your Nessus sign, degree, house, and any natal aspects within a tight 2° orb. Positions come from JPL ephemeris data, the same source the rest of the Augurine engine reads. The sign and house entries below give you a written interpretation block by block; the calculator points you to the one that matches your placement.
The stance this page takes
Most Nessus writing online flattens into two readings. One: this is the asteroid of the abuser. Two: this is the asteroid of the victim. Both readings are wrong, and both do harm.
Nessus does not assign roles. It names a pattern available for interruption. Some people inside that pattern repeat it. Some attract it. Some internalize it and turn it inward. Some look at it clearly, name it, and stop the transmission. The chart shows you which patterns are nearby. The role is decided by you, over years, often after the pattern has already been visible for a while. Read every block on this page with that in mind.
How to read your Nessus placement
Sign first. The sign Nessus occupies tells you the style of the pattern: how it tends to enter the room, what it sounds like, where it usually gets named. Read the entry above that matches your placement.
House next. If you have an exact birth time, your Nessus also lands in a specific house, which tells you where in the life the pattern usually plays out. Sign is style. House is venue.
Aspects last. Tight contacts under 2° to natal planets and angles thicken the picture. Conjunctions to the Sun, Moon, Ascendant, or Midheaven are the most noticeable. Read aspects as showing which other parts of the chart are part of the pattern, not as fate.
Nessus in the centaur family: Chiron, Pholus, Nessus
Nessus is not a stand-alone curiosity. It is one of three named centaurs that operate as a group in modern astrology, and the readings sharpen when the trio is held together.
Chiron (2060) is the wound and the teaching that comes from working on it. Pholus (5145) is the small action with the disproportionately large consequence, often a lid lifted on a much larger container. Nessus (7066) is the recurring pattern of harm and the point at which the pattern can be interrupted. Chiron tells you where the wound is. Pholus tells you where the small action triggers the large consequence. Nessus tells you what the pattern looks like once the consequence arrives and starts repeating.
If you are working with Nessus seriously, run Chiron alongside it. The two contacts often tell you, together, why a particular pattern is the one your chart is built to work on.
Nessus aspects to natal planets
Aspects narrow the picture. Sign and house tell you the style and the venue; aspects tell you which other parts of the chart are part of the pattern. The standard orb for Nessus contacts on this page is 2°. Anything wider, treat as background.
With the Sun or Moon, the pattern is involved with identity or with the emotional body, and contacts to the Moon are the most common signature of a Nessus theme that took years to name. With Mercury, the pattern lives in language. With Venus, in love and self-worth. With Mars, in anger and initiation. With Saturn, the pattern is structural and time-shaped. With Pluto, it is total, and not a contact you intellectualize your way out of.
Aspects to Chiron are often the place where the breaking actually happens: the wound has already been named, and the same patience now turns toward the pattern.
Nessus in synastry
Two charts overlaid, each person's Nessus sits on the other person's planets, and the question of who carries what becomes visible. The framing matters here more than anywhere else.
A Nessus contact in synastry does not say one person is the abuser and the other is the victim. It says the two of you have a shared theme available, the theme has roles, and the roles can be swapped, declined, or interrupted. Read the contact as the dynamic between you, not the assignment of guilt.
Your Nessus on a partner's Sun or Moon means the theme lands in their identity or emotional body, and they will remember moments that felt like the pattern more clearly than you will. Take their memory seriously. The reverse is also true: their Nessus on your planets reads the same way, with the roles inverted.
Where Nessus is right now, and what transits feel like
Nessus moves about 3° per year on average, so a transit to a natal point can last a long time. When transiting Nessus is within 2° of a natal planet or angle, that part of the chart is currently inside the theme.
Nessus crossing a natal Sun or Moon brings the theme into identity or emotion for several years. Nessus crossing an angle (Ascendant, IC, Descendant, MC) makes the theme visible in a major life arena. Nessus retrograde over a natal point usually correlates with the internal phase of the theme: less acted out, more felt. These windows are often when the pattern becomes nameable for the first time.
Disambiguation: Nessus and bodies it is often confused with
Nessus is not Black Moon Lilith. Black Moon Lilith is a mathematical point, the empty focus of the Moon's elliptical orbit. Nessus is a physical body, minor planet 7066. If you are looking for the lunar point, use the Lilith Sign Calculator.
Nessus is not Asteroid Lilith (1181) either. That is a small asteroid in the main belt, a different body and a different reading. The All Asteroids Calculator covers Asteroid Lilith and the wider asteroid set.
Nessus is not Chiron, and it is not Pholus. Those are centaurs 2060 and 5145, and each has its own reading. Use the Chiron calculator linked above when you want the Chiron contact specifically.
Nessus through the 12 zodiac signs
A short interpretation of Nessus in each zodiac sign. Read the entry that matches your placement above. The other entries give you the texture and shape of the archetype across the full wheel.
Nessus in Aries
loud pattern, fast interruption
Nessus in Aries names a pattern that tends to arrive loud. Quick temper, quick apology, quick repeat. The pattern is available, not assigned: the same placement can describe someone who keeps repeating the loop and someone who became fluent at naming what they feel before they act on it. The interruption point is the half-second between the trigger and the reaction.
Nessus in Taurus
slow pattern, material cost
Nessus in Taurus names a pattern that moves slowly and shows up in material life. Staying because leaving costs money, staying because the house is nice, staying because nothing dramatic has happened recently. The interruption point is the question 'what am I actually paying for this,' asked honestly rather than rhetorically.
Nessus in Gemini
pattern in language
Nessus in Gemini names a pattern that lives in language. Sharp messages sent late at night, conversations that turn the moment a direct question lands, the script that always wins the argument. The interruption point is the unsent draft. Writing the message and leaving it overnight is often most of the work.
Nessus in Cancer
ancestral pattern, named at last
Nessus in Cancer names a family-shaped pattern. Roles inherited from a parent or grandparent that nobody named but everybody played. The interruption point is the first time someone in the lineage refuses the assigned role and tolerates the silence that follows. The placement is common in people who become the ones who finally name it.
Nessus in Leo
pattern behind performance
Nessus in Leo names a pattern that hides inside performance. The version of you that gets loved is not the version that is real, and the cost of keeping the loved version visible is large. The interruption point is being seen on a Tuesday, in regular clothes, not doing anything impressive, and having that count as enough.
Nessus in Virgo
pattern dressed as help
Nessus in Virgo names a pattern that wears the clothes of help. Care that arrives with a bill attached, correction that runs longer than it needs to, fixing that keeps the other person dependent. The interruption point is the difference between help that builds the other person's capacity and help that quietly preserves the dynamic.
Nessus in Libra
pattern hidden in peacekeeping
Nessus in Libra names a pattern that enters through the wish to keep the peace. Conflict gets postponed, postponed again, then explodes. Or it is held inside and the body carries it. The interruption point is one direct conversation, scheduled, survived, and not undone by the apology that arrives afterward.
Nessus in Scorpio
loyalty becomes a hold
Nessus in Scorpio is most at home in this sign, and the reading is the most direct. Loyalty that becomes possession, intimacy that becomes a hold, secrets used as currency. The interruption point is full disclosure of one thing that has been held back. That single act often changes the temperature of the entire pattern.
Nessus in Sagittarius
pattern hidden in belief
Nessus in Sagittarius names a pattern that hides inside the larger story. Harm justified by a worldview: 'I had to do that because of my philosophy, my faith, my freedom.' The interruption point is asking whether the worldview is being used as a worldview or as a permission slip.
Nessus in Capricorn
structural pattern, quietly held
Nessus in Capricorn names a structural pattern. Power held a long time, used quietly, never quite questioned. Often inside families, sometimes inside companies. The interruption point is the moment a younger person asks 'why are we doing it this way' and the older person decides to answer honestly instead of defending the structure.
Nessus in Aquarius
pattern hidden in the group
Nessus in Aquarius names a pattern that hides inside the group. Belonging that is conditional on agreeing, ideology that requires an excluded person to stay coherent, the in-group that needs an out-group to exist. The interruption point is one defense of the excluded person, made out loud, in front of the group.
Nessus in Pisces
atmospheric pattern, absorbed
Nessus in Pisces names a pattern that dissolves into atmosphere. Hard to point to, easy to absorb. Often shows up as the person who carries everyone else's emotional debt without anybody noticing, including themselves. The interruption point is the first time you say 'this is not mine' and let the feeling go back where it came from.
Nessus through the 12 houses
If you have an exact birth time, your Nessus also lands in a specific house, the life area where this prompt may be easiest to notice. Without a birth time, use the sign placement as the steadier read and skip this section.
Nessus in the 1st house
Nessus in the 1st can fuse the pattern with identity. People meet you and meet the loop at the same time. The work is separating the loop from who you are underneath it, which is slower work but real.
Nessus in the 2nd house
Nessus in the 2nd can put the pattern around money, possessions, and self-worth. Worth measured externally, money used as a hold. The interruption point is decoupling worth from inventory.
Nessus in the 3rd house
Nessus in the 3rd can place the pattern in daily conversation, siblings, and neighbors. The pattern is communicational and often built from small recurring rhetorical moves rather than dramatic events.
Nessus in the 4th house
Nessus in the 4th can place the pattern inside home and family of origin. Ancestral material is common here. The work is generational, and often quiet: refusing one inherited role and tolerating the family's response.
Nessus in the 5th house
Nessus in the 5th can place the pattern around children, creativity, and romance. It often shows up in early love affairs and in how the people closest to you treat your creative work. The work is protecting the unfinished thing.
Nessus in the 6th house
Nessus in the 6th can place the pattern inside work, daily routine, and health. It hides inside chores and inside who does the invisible labor. The interruption point is making the invisible labor visible.
Nessus in the 7th house
Nessus in the 7th can place the pattern inside one-to-one partnership. The dynamic is relational and reciprocal: whatever Nessus is doing here is also being done back. The work is naming the dynamic without trying to assign who started it.
Nessus in the 8th house
Nessus in the 8th can place the pattern around shared resources, sex, and deep intimacy. The signature here is the quiet hold one person has over another. The interruption point is naming the hold so it stops being unspoken.
Nessus in the 9th house
Nessus in the 9th can place the pattern inside beliefs, travel, and teachers. The pattern hides inside ideology. The work is checking whether your beliefs are belonging to you or being used against you.
Nessus in the 10th house
Nessus in the 10th can place the pattern in public role, career, and authority. Often visible: harm that happens at work, harm done from a position of authority, or harm done to you by one. The work is keeping the public role clean.
Nessus in the 11th house
Nessus in the 11th can place the pattern inside friend groups, networks, and causes. The interruption point is being the person who declines to participate when the group turns on someone.
Nessus in the 12th house
Nessus in the 12th can place the pattern in the hidden, internalized, ancestral layer. Often invisible to you and visible to everyone else. The work is therapeutic and slow, and bringing the pattern into language is most of the job.

Frequently Asked Questions
What is asteroid Nessus (7066) in astrology?
Nessus is minor planet 7066, classed as a centaur, with an orbit between Saturn and Pluto. In modern astrology it can be read as a prompt for cyclical patterns of harm and the point at which the cycle becomes interruptible. It is not a verdict on character. The chart names the pattern; the role inside it is not assigned by the placement.
How do I find my Nessus sign?
Enter your birth date, time, and place above. The calculator computes centaur 7066 Nessus at your birth moment from a local JPL SBDB-derived Keplerian element set and returns the sign, degree, and house when birth time and location are known. Nessus moves slowly, roughly 3° per year on average, so its sign placement stays steady for several years at a time.
Is Nessus the asteroid of abuse?
No, and the question is the wrong frame. Nessus names a pattern of cyclical harm and an interruption point inside it. The same placement can describe someone who keeps repeating the pattern, someone who absorbs it, and someone who became the person in the lineage who finally named it and stopped the transmission. Read it as a pattern available for interruption, not as a role assignment.
Is Nessus an asteroid or a centaur?
Both. The technical classification is centaur, a small group of minor planets with orbits between Jupiter and Neptune. Nessus is also minor planet number 7066. Calling it 'asteroid Nessus' or 'centaur Nessus' refers to the same body. Chiron and Pholus are also centaurs and form a group with Nessus that is often read together.
What orb should I use for Nessus aspects?
Two degrees is a standard. Anything wider than that we treat as background for this calculator. Tight conjunctions, oppositions, and squares read most reliably; trines and sextiles register as available rather than active.
What if I don't know my exact birth time?
You will see the Nessus sign, which is the steadier read for a slow-moving body. The house section depends on the hour of birth, so it is skipped when birth time is unknown. The interpretation on the sign section is the main thing to read.
