How accurate is Planetary Ephemeris Chart?

Planetary Ephemeris Chart draws on centuries of accumulated wisdom from spiritual traditions — not on scientific prediction algorithms. The Rider-Waite-Smith tarot tradition, Pythagorean numerology, and Western astrology are symbolic frameworks designed to support self-reflection, not to forecast external events with certainty. Results from Planetary Ephemeris Chart are best understood as mirrors for your own inner state, inviting you to explore patterns, possibilities, and meanings that resonate with your current situation. Many users find them valuable for clarity and perspective, while maintaining personal discernment about any guidance they receive.

Is my data private when I use Planetary Ephemeris Chart?

Absolutely. Planetary Ephemeris Chart processes everything in your browser. No personal data — not your birth date, your questions, or your results — is ever sent to a server. There is no account system, no tracking of individual readings, and no way for anyone (including Astralium) to see what you do with Planetary Ephemeris Chart. Your spiritual practice remains yours alone.

What is an ephemeris?

A table or graph that shows the positions of celestial bodies over time. Astronomers and astrologers both use them.

Why does Mercury sometimes appear to go backwards?

That is the famous Mercury retrograde. The chart shows it as a dip — Mercury’s longitude moving against the usual direction over a few weeks.

How accurate are these positions?

They use mean orbital elements (Meeus-style) and are typically within 1° to 2° of professional ephemerides — fine for sign placement and visualization, not for navigation.

Can I see future years?

Yes — you can pick any year between 1900 and 2100.

Why are the lines sometimes broken?

When a planet wraps from 360° back to 0° (Pisces to Aries), we break the line on purpose so the visualization stays clean.
