Pluto
Pluto is astronomically classified as a dwarf planet. Modern astrology continues to use it as a symbolic factor.
How it is defined
Placing a factor in a chart requires a date, an instant and a reference frame. Sign, house and aspect answer different questions: zodiac position, chart sector and angular relationship. They should not be treated as interchangeable.
How to read it
It is associated with intensity, power relationships and processes of transformation.
