B
Astronomy & calculated points

Black Moon Lilith →

Also: Mean Lilith

An astrological lunar-apogee point, with several calculation conventions; it is distinct from asteroid 1181 Lilith and hypothetical dark-moon models.

Word origin, evidence & sources
Word origin · etymology
Modern astronomical nickname with a mythological name.

Black Moon is a descriptive occult label; Lilith is borrowed from the Hebrew name of a female demon. Deeper derivations are not assumed here.

How we know · epistemology
Astrological label for calculated points

Different Lilith calculations select different lunar-apogee models. Reproducible comparison requires the exact point and method; shared mythology does not make an apogee, an asteroid and a hypothetical dark moon the same astronomical object.

H
Astronomy & calculated points

Hypothetical Uranian point →

Also: Uranian hypothetical bodies

A mathematically modelled point used in the Hamburg School, such as Cupido or Hades; these are not confirmed physical planets.

Word origin, evidence & sources
Word origin · etymology
Modern school name with a descriptive qualifier.

Uranian identifies the Uranian astrological school; hypothetical marks its proposed points. The phrase does not describe a confirmed body orbiting Uranus.

How we know · epistemology
Unconfirmed mathematical model

The Hamburg School uses prescribed hypothetical orbits to supply these chart points. Software can reproduce their positions, but that agreement does not constitute an astronomical detection or establish that the proposed planets physically exist.

L
Astronomy & calculated points

Lunar apogee →

Also: apogee

The farthest point of a lunar orbit from Earth; an apogee direction is a geometric point, not another moon.

Word origin, evidence & sources
Word origin · etymology
Latin adjective and Greek-derived noun.

Lunar means of the Moon; apogee derives from Greek apo-, away, and ge, Earth. Together they name the Moon's farthest orbital point.

How we know · epistemology
Orbital distance geometry

Lunar distance observations and orbital calculations identify farthest-distance points or events. A chart's apogee direction requires a stated model; it should not be confused with an additional object occupying that position.

M
Astronomy & calculated points

Mean node →

Also: Mean North Node

A smoothed model of the lunar node, omitting short-period oscillations.

Word origin, evidence & sources
Word origin · etymology
Descriptive mathematical qualifier.

Mean names an averaged representation; node comes from the Latin word for knot. The phrase distinguishes the smoothed nodal model.

How we know · epistemology
Smoothed orbital model

Averaging removes short-period variation to provide a regular node trajectory. The result is a deliberate model, not a less carefully observed planet; comparisons with true-node positions must account for the different quantities being represented.

N
Astronomy & calculated points

North lunar node →

Also: ascending lunar node · North Node

The point where the Moon’s orbit crosses the ecliptic from south to north.

Word origin, evidence & sources
Word origin · etymology
Descriptive astronomical phrase with Latin roots.

Node comes from nodus, knot. North specifies the crossing where the Moon goes toward the north side of the ecliptic.

How we know · epistemology
Orbital intersection geometry

The node follows from the Moon's orbital plane crossing the ecliptic northward. It helps describe eclipse geometry, but it is a location defined by planes rather than a body that emits a distinct influence.

O
Astronomy & calculated points

Osculating apogee →

Also: True Lilith

The apogee of an instantaneous fitted lunar orbit; its changes include short-period effects and differ from the mean apogee.

Word origin, evidence & sources
Word origin · etymology
Latin and Greek mathematical vocabulary.

Osculating comes from osculari, to kiss; a locally fitted orbit metaphorically kisses the actual trajectory. Apogee means far from Earth.

How we know · epistemology
Instantaneous fitted-orbit geometry

An ellipse fitted to the current lunar state supplies this apogee. Perturbations continually change that fit, so its direction is not necessarily the place of the Moon's next actual greatest distance from Earth.

R
Astronomy & calculated points

Retrograde →

Also: retrograde motion

Apparent backward movement in a selected, usually geocentric, coordinate frame; it does not mean that a planet physically reverses its orbit.

Word origin, evidence & sources
Word origin · etymology
Latin through Middle English.

Retrogradus means going backward, from retro- and gradi, to step or go. The chart usage describes apparent backward longitude motion.

How we know · epistemology
Apparent motion in a reference frame

Successive positions establish whether longitude is increasing or decreasing in the declared frame. In a geocentric chart this can be an apparent reversal produced by relative motion and viewpoint. Traditional horary associations such as delay, return, or reversal are interpretive and require the rest of the selected method; they are not measured consequences of the motion.

S
Astronomy & calculated points

Stationary →

Also: planetary station

A moment when apparent longitudinal motion passes through zero near a change between direct and retrograde motion.

Word origin, evidence & sources
Word origin · etymology
Latin-derived English adjective.

Stationary belongs to the station family, from Latin statio, a standing. The term names an apparent pause in a body's longitudinal movement.

How we know · epistemology
Instantaneous motion criterion

A station is located by solving for zero longitudinal speed in a specified frame. A display that rounds a small speed to zero is not an exact station; practical station windows require a separately declared tolerance.

T
Astronomy & calculated points

True node →

Also: True North Node

A node calculated from the Moon’s instantaneous orbital geometry; it can briefly move direct despite the mean node’s retrograde motion.

Word origin, evidence & sources
Word origin · etymology
Historical astronomical model label.

True is the conventional counterpart to mean, indicating an instant-dependent rather than averaged node. The adjective is part of the model's name.

How we know · epistemology
Instantaneous orbital model

The calculation uses the Moon's instantaneous orbital geometry, retaining variations omitted by a mean model. True names that modeling choice; it does not establish that this node convention produces truer astrological interpretations.
