Conjunction: 0° and the Orb

The geometric relationship

An aspect uses the shorter circular distance between two ecliptic longitudes. The exact target for a conjunction is 0°. A difference exceeding 180° is subtracted from 360°. This also handles placements across the 0°/360° boundary correctly. A general relationship between signs and an exact degree-based aspect are different layers.

Orb: distance from exactness

For example, take longitudes of 12° and 14°. Their shorter separation is 2°, making the orb from the conjunction target 2°. Starmora uses a 8° limit for this aspect, capped at 3° for pairs containing a lunar node. This is a method convention rather than calculation error or a rule shared by every astrologer.

Symbolic interpretation

A conjunction places two bodies near the same longitude. Its symbolic reading examines themes working closely, joining or becoming harder to separate. A conjunction is not inherently favourable or unfavourable; the particular pair matters. Mercury–Venus and Mars–Saturn do not open the same question.

Natal, transit and synastry

A natal aspect relates two bodies at birth. A transit relates a body at the chosen time to a natal position; synastry relates the natal positions of two people. The same aspect name does not make these contexts identical. The orb alone cannot establish applying or separating motion: direction and change over time must also be calculated.

Read the line alongside the interpretation

The chart connection joins the actual longitude points rather than necessarily the centres of symbols displaced for readability. The table shows separation and orb separately. A near-limit aspect can change inclusion with a small input difference. First identify the connected bodies, then add their signs and houses.

Write an example where you notice both themes in one action, then one where you can approach them separately. A conjunction does not require the two themes always to carry the same wish.
