The most precise planetary aspects right now.

An aspect is the angle two bodies hold to one another. It reaches exactitude when that angle equals the aspect's defining value — 90° for a square, 120° for a trine — and the angular deviation is how far the measured separation currently sits from it. Nothing here is forecast: every figure is the angle as measured from current ephemeris, timed to the minute.

The table is the current exactitude ranking — sorted by angular deviation, closest first, across both frames: geocentric (angles as seen from Earth) and heliocentric (as seen from the Sun).

Phase is applying where the pair is still closing on exactitude and separating where it has passed it. It is read from the solved exact instant rather than inferred from average speed, so a retrograde body is described correctly; where the register holds no solved instant the column shows an em dash rather than a guess.

Exactitude is stated as a percentage of the 2° orb — 100% at the exact instant, 0% at the edge of orb — so it is a restatement of the angular deviation beside it, not a separate measurement. It is shown only for aspects inside the orb, where it means something.

Time until exactitude is the interval to the solved exact instant, and it is the reason this is a planetary aspect timer rather than a snapshot. Most sites publish which aspects are in effect today; the current planetary aspect exactitude — the angle to three decimals and the minute it perfects — is the measurement almost nobody else states, and it is what the whole instrument exists to produce.

The player above voices the top-ranked pair. Planetary aspect precision is audible as well as numeric: each angle carries a harmonic ratio, applied to the two bodies' own frequencies, so the aspect this table ranks first is the aspect you hear. The six intervals set that out in full.
