Ephemeris Astro Search: query builder

A professional tool for astrologers and researchers. Set your own query: a planet in a sign or degree, an aspect of two planets, a conjunction with a fixed star, or a figure of three to six planets — with any planets, in the desired element, cross or signs, with your own orb. Search through past and future skies for the entire depth of the ephemerides, free and without registration.

Describe your query in words — the form will fill itself in

Planet

Sign (or filter below)

Absolute degree from (0–360)

Absolute degree to (0–360)

Sign, absolute degrees, or the “Where” filter — one condition is enough.

Planet

Star

Orb, °

Where: elements, crosses, signs, degrees within sign

Degree within sign to (0–30)

Degree within sign from (0–30)

The filter is applied to all participants of the query: 'trapezium in fire' — all four planets in fire signs. Elements, crosses and signs narrow each other.

Year from

Year before

Maximum periods

Years BCE — with a minus sign: −500 = 501 BCE (astronomical count). Window of one query: up to 2000 years for positions and stars, 1000 for aspects, 500 for figures — further, scroll with the buttons.

What does this mean for you personally? Найденный аспект или фигура работает по-разному в каждой натальной карте. Build your chart — и получите персональный разбор: как этот аспект проявляется в вашем характере, отношениях и выборе времени.

Example queries

All cradles (trapeziums) in fire signs from 1950 to 2040, orb 2° — four 'any planet' slots, filter 'Fire'.
Any planet in the 29th degree of any sign in conjunction with any other: two 'any' slots, aspect 'Conjunction', filter 'degree within sign 29–30'.
Conjunction of any planet with the star Algol in 2026–2030, orb 1°.
T-square in cardinal signs for the 20th century: the Moon is disabled to see only slow configurations.
Jupiter–Saturn conjunction with 1° orb in 1000 BCE: year from −1000 to −1.

How it works

The engine stores daily ecliptic longitudes of ten planets for the entire depth of the Swiss Ephemeris — more than twelve thousand years back and forward — and searches through ready-made series, so the answer comes in seconds. For each period, the start and end dates, the exact date of the minimum orb, the orb itself, the participants and their positions at the exact moment are shown. The 'any planet' slot turns the query into a brute-force search: the engine checks all combinations and returns each found one as a separate period. The 'Where' filter is applied to the position of each participant: element, cross, specific signs and degrees within a sign. The orb for figures is strict — each connection of the configuration must be within the specified orb. The positions of fixed stars are reduced to the J2000 epoch and shifted by precession.
