Moon stands for instinct, emotional need, and what makes you feel safe. It rules cancer, and the 4th-house themes of home and origins. Astronomically it is Earth's companion: the fastest body in the chart, and the one that sets the tides of mood.

The astronomy, briefly
Astrology ignores almost nothing about the sky, but it does sort bodies by how fast they move. Moon takes 27.3 days around the zodiac (about 2.5 days per sign). That pace matters: fast bodies describe personal, day-to-day patterns, while slow ones describe whole generations. When someone says “everyone my age has Pluto in the same sign,” this is why.
Reading Moon: the three questions
Every placement answers three questions. What is it (the planet: here, Moon)? How does it behave (the sign)? Where does it act (the house)? Take Moon in Aquarius, the receipt above. You would read the function (instinct, emotional need, and what makes you feel safe) in Aquarius's style, and then look up which house it occupied that day for that observer. Same planet, different story per person. The house is why two people with the same placement can live it differently.
