Moon
What you need to feel safe.
In a birth chart, Moon describes your inner life — feelings, instincts, what you need to feel safe.
What it actually is
A quarter of Earth's diameter and the largest moon relative to its planet in the solar system. It moves about 13° a day, faster than anything else in a chart.
In a chart: Roughly two and a half days in each sign, which is why an exact birth time matters most for the Moon.
How Moon is read
At its best
Emotional fluency — knowing what you feel while you feel it, and being a safe place for other people to put things down.
The difficult end
Moods treated as weather that everyone else must live in. Needs expressed as sulking rather than sentences.
What to do with it
Name the need before it becomes a mood. The Moon is the one part of a chart that asks rather than performs.
What Moon rules
Traditionally Moon rules Cancer. If one of those is your rising sign, Moon is your chart ruler — the planet a traditional reading treats as standing for you.
The metal of Moon
Silver Ag
Silver is the most reflective of all metals, which earned it the Moon. Read as receptivity — you take the shape of what you are near, and see clearly by reflected light.
The other chart bodies
Where is Moon in your chart?
Its sign says how it acts; its house says where in your life it acts. Both come from real positions at your birth moment.
