Outer Planets
Uranus, Neptune, Pluto - generational forces of collective change.
Outer planets (Uranus, Neptune, Pluto) move slowly, staying in each sign for years or decades. They describe generational themes rather than personal traits. Their sign placements are shared by everyone your age, but their house placements in your chart show where these collective forces play out in your personal life. Transits from outer planets mark major life chapters.
Example
Everyone born roughly 1984-1998 has Pluto in Scorpio, but where Pluto falls in your houses determines how this generational intensity affects your personal life.
