Planets in the zodiac signs

Ten bodies — the Sun, the Moon and eight planets — in twelve signs make 120 pages. Each one says what the planet is in charge of in a chart and how the sign changes the way it shows up, then gives its element, modality, ruler and dignity, and the dates when the planet was actually in that sign.

Your natal chart tells you which pages are yours: it shows where every planet stood when you were born. The Sun, Moon, Mercury, Venus and Mars move fast, so people born a few weeks apart already have them in different places. Uranus, Neptune and Pluto stay in one sign for years, which means everyone born in the same stretch of years shares their placement.
