Ephemeris Sky

Ephemeris Sky turns any moment in time into a precise picture of the solar system - and the cycles that drive astrology. Pick a date, time, and time zone - then step forward or back by hour, day, or week - and Ephemeris Sky instantly computes: POSITIONS Real geocentric positions for the Sun, Moon, and the planets out to Pluto - tropical, referred to the equinox of date, the same convention professional astrology software uses. See each body's sign, exact degree and minute, and daily motion, with retrograde clearly marked. ASPECTS Every aspect between the planets - conjunction, sextile, square, trine, opposition - computed from the positions and ranked by exactness. Move the orb slider to widen or tighten what counts. CHART WHEEL A clean, live chart wheel with the zodiac ring, planet glyphs, and color-coded aspect lines that redraws instantly for any date. SYNODIC CYCLE (the part most apps skip) Track each planet's full cycle relative to the Sun: inferior and superior conjunctions, the retrograde and direct stations (the famous "U-turns"), and greatest elongations - each with a real date. See exactly where Mercury is in its cycle right now, when the next Mercury retrograde begins and ends, and the same for every planet.
