Your sky, precisely calculated
Stellaro.net computes birth charts, Human Design charts, transits and partnership comparisons from real ephemerides – sidereal and tropical, with nakshatras, houses and aspects. Plus an AI reading that actually argues from your chart – in six languages: German, English, Spanish, Portuguese, French and Italian.
Calculation before speculation
Astronomy comes first. Interpretation comes after.
Real ephemerides
Swiss Ephemeris based on DE431 – no approximations. Including Chiron, Lilith and the lunar nodes.
Sidereal & tropical
Lahiri ayanamsa for Jyotish, tropical zodiac for Western astrology. You decide per chart.
27 nakshatras
Lunar mansions with padas and Vimshottari rulers, derived cleanly from the actual degrees.
Human Design
Bodygraph with gates, channels, centres, type, authority, profile and incarnation cross.
Zodiac mandala
Gates, zodiac and bodygraph in one drawing – plus the chart wheel and bodygraph as separate graphics.
House systems of your choice
Placidus, Koch, equal houses, whole sign, Campanus or Regiomontanus.
Transits & partnership
Current transits to your natal chart and a comparison of two charts – each with its own reading.
AI reading with follow-up questions
A reading that quotes your actual chart, a chat to dig deeper, saving in your own area and PDF export.
StarNews
A daily astrological reading of the current mood of the times – not news, not a forecast.
Star Weather
Measured space weather from NOAA – and beside it, clearly separated, the astrological reading of the day.
Quotas instead of fine print
Calculations are unlimited. The only limit is how many AI readings are included per month.
