As the outermost planet in our solar system, Pluto is also the farthest from the Sun. It has only recently been discovered, having come to light (albeit a dim one) in 1930.
Pluto's energy may be subtle, but its results will hit you like a ton of bricks. This planet is about transformation, regeneration and rebirth. Things aren't pretty with Pluto, but they do get done. Pluto says 'out with the old and in with the new,' and we'd better be ready for it. If we're not, this planet will simply have us wallow in our misery. Pluto asks us to transcend that which we know, redeem ourselves in the process, and come out stronger as a result.
For all that Pluto (re)creates (it also governs the reproductive system), it loves to destroy. This planet rules destruction, death, obsession, kidnapping, coercion, viruses and waste. That's definitely not pretty. Pluto also governs crime and the underworld, along with many forms of subversive activity (terrorism, dictatorships). This planet is about all that is secret and undercover, that which is hidden from view. Is this the story of good vs. evil? Yes.
No one will deny Pluto's power (it rules atomic power, too) and intensity. This planet's energy is often focused on the masses and what the collective will do. Pluto beseeches the masses to look inward (and to their subconscious) to see what's there. It may be scary, but Pluto doesn't care. This planet knows how to push buttons.
It takes Pluto approximately 248 years to complete its orbit around the zodiac. Due to the eccentricity of its orbit, it takes this planet between 12 and 31 years to pass through a sign. It rules Scorpio and the Eighth House. Pluto is the last of the transcendental planets and is the higher octave of Mars.
