The retro list is a table of contents. How the inward planets get along with the rest of the chart — and where their depth becomes strength — is what Luna reads from the full natal chart.
Read my chartHow to find the retrograde planets
No tables needed: retrogradation is the sign of a planet’s speed in the ephemerides for the birth date. The calculator above checks all ten planets with Swiss Ephemeris — the same engine that builds the natal chart in the app. The Sun and the Moon are never retrograde: seen from Earth they simply do not back up. Birth time does not matter here — a planet reverses direction once in weeks or months, not hours.
What retrograde means for each planet
- ☿Mercury
the mind works inward: think first, speak second; strong writing and an editor’s eye
- ♀Venus
feelings live inside and open slowly: a personal value system instead of a fashionable one
- ♂Mars
force accumulates and fires precisely: action after ripening, not on impulse
- ♃Jupiter
growth through one’s own experience rather than borrowed authority: personally tested faith
- ♄Saturn
the inner core is self-built: rules of one’s own, not imposed ones
- ♅Uranus
freedom lives inside: quiet revolutions, but irreversible ones
- ♆Neptune
a rich inner cinema: intuition and creativity run deeper than they show
- ♇Pluto
transformation happens at depth: change ripens long and then changes everything at once
How many retrograde planets is normal?
On average a person has two or three retrograde planets — that is orbital statistics, not a twist of fate. Zero retro is normal too (roughly one person in ten). Four or more is a rarity that reads as a deeply “inward profile”, not a problem: the social and outer planets (Jupiter through Pluto) spend a third to a half of every year in retrograde, which is why they are the usual suspects.
Frequently asked questions
Is the meme “Mercury retrograde” the same thing?
No. The memes are about transiting retrograde Mercury: a calendar period shared by everyone. Natal retrograde Mercury is a personal chart trait: a mind that thinks first and speaks second. The transit passes in three weeks; the natal one is a way of thinking for life.
I have many retrograde planets. Is that bad?
No. Many retros make a deep inward profile: those planets’ themes live inside and unfold with time. The outer planets are retrograde in almost half of all charts — a generational backdrop, not a personal verdict.
Can the Sun or the Moon be retrograde?
Never: apparent backward motion comes from orbital overtaking, and the Sun and Moon do not move that way relative to Earth. A site showing a “retrograde Moon” has a calculation bug.
Is an exact birth time needed for retrogradation?
No. A planet reverses direction once in weeks or months, so the date is enough. The time is needed for something else — houses and the ascendant.
Calculating the positions is astronomy; interpreting them is a symbolic system for self-reflection, not science.
Retro is not a defect — it is a timbre
Luna reads retrogradation in the context of the whole chart: sign, house, aspects. Real ephemerides, plain words, voice — and no “karmic debts”.
