Pluto - Ruler of Scorpio
Pluto Lord of the Underworld, governs the unconscious mind, as well as hidden riches. Secrets, intense emotions, soul truths and sudden endings and beginnings are also ruled by mysterious Pluto, the most recently discovered and most distant of the planets. It gives magnetism and an almost X-ray insight into others' motives. Its position at birth shows where change and soul growth can occur.
It is the planet of the masses and stands for regeneration, change and transformation. Its house position in your chart and the links it makes to other planets, show your unconscious motivations and your most intense - and hidden - feelings. Secretive Pluto gives depth and passion to any planet that it touches, making it hard to be objective and detached. Because it is the furthest planet from the Sun, Pluto takes so long to travel through one zodiac sign that you share its influence by sign with your whole generation, as you do with Uranus and Neptune.
