DATA FIRST, MEANING SECOND
How to read this page without confusing astronomy and astrology
What can be calculated
Phase, illuminated percentage, waxing or waning direction, longitude and Moon sign derive from the geometry of the Sun, Moon and Earth. They are verifiable and reproducible data.
What astrology interprets
Associations between lunar phases, emotions, beginnings or endings belong to astrological tradition. They can support reflection, but do not demonstrate a causal effect.
What is the terminator?
It is the line separating day and night on the lunar surface. Near it, terrain shadows are longer, making craters and mountains appear more prominent.
Why does the Moon appear to change shape?
The Moon does not change shape. We see different portions of its illuminated hemisphere as the geometry between the Sun, Earth and Moon changes.
What does waxing mean?
It means the visible illuminated fraction increases day by day toward the full moon. Waning describes the opposite path toward the new moon.
