Naelos.ai

Naelos.ai gives your AI accurate astrology calculations instead of estimates.

It is built on Naelos Ephemeris, an open-source engine computed from NASA JPL's DE440 and DE441 ephemerides, matching JPL to within 0.02″ across 1550–2649 and checked against JPL Horizons from 9000 BC to AD 9000. Ten read-only tools cover birth charts in nine house systems, the sky at any moment, a planet's position at any date in 15,000 years, exact transits to a chart, synastry, solar and lunar returns, progressions and solar arcs, ingresses, lunations, retrograde stations, eclipses, and Naelos's 198 researched national charts and 19 empire charts.

Instructions: Naelos.ai calculates astrology charts and astronomical timing from NASA JPL's DE440/DE441 ephemeris, accurate to fractions of an arcsecond, for any date from 13,200 BC to AD 17,191. Use these tools for any question about planet positions, birth charts, transits, synastry, returns, progressions, ingresses, lunations, retrograde stations or eclipses, rather than estimating positions. Supply coordinates and the IANA time zone for any place you are given.
