They say Scorpio's planet is Pluto?
What is the explanation for that now?

Pluto is now called a "dwarf planet" by the International Astronomy Union. This is because the IAU created a definition of the word "planet" for the first time last summer, and Pluto did not satisfy it. The new definition requires that a celestial body be massive enough that gravity compacts it into a spheroid but not so massive that nuclear fusion occurs at its core, and that it orbit the Sun but not a planet. It also requires that the body "clear the neighborhood of its orbit." An object like Pluto or the asteroid Ceres that satisfies all but the last condition is instead called a dwarf planet. Pluto has not cleared its neighborhood because its orbit intersects those of many other similar bodies.
I happen to be a Scorpio by standard reckoning, and I can tell you quite definitely that the explanation for Pluto being Scorpio's governing "planet" is that astrology is pure quackery with no basis in science. The normal dates for astrological signs do not even correspond to the Zodiac constellations in which the Sun rises over the course of the year!

Pluto is considered a Dwarf Planet, now...
To quote from the Dwarf Planet Wiki:
"The International Astronomical Union (IAU), the official scientific body for astronomical nomenclature, defines a "dwarf planet" as a celestial body within the Solar System that satisfies these four conditions:[1]
1. is in orbit around the Sun
2. has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (near-spherical) shape
3. has not cleared the neighbourhood around its orbit
4. is not a satellite
The term "dwarf planet" was adopted in 2006 as part of a three-way classification of bodies orbiting the Sun. Objects that are large enough to have cleared the neighbourhood of their orbit are defined as "planets", while those which are too small to be in hydrostatic equilibrium are defined as "small solar system bodies". As defined, the term "dwarf planet" does not apply to other planetary systems.[2]
Three dwarf planets are currently recognized: Ceres, Pluto and Eris."

About Scorpio's planet being Pluto... I wouldn't worry about it. when astrology was first developed (it was used in China three thousand years ago) they never heard of Pluto... things change :)

To add to the above answer, if you count Pluto as a planet based on its size and orbit then as a result thousands of other "dwarf" planets would be added that exist on the outskirts of our solar system.

Pluto is still a planet...just a lesser type of one..a "dwarf planet." It is classified as a dwarf planet because it does not dominate the space around it.

A bunch of renegades got together and decided this. It would be like a group of people getting together calling themselves Building expects and claiming that your house is not a building because of it size. Pluto will always be a planet and unless a new one falls in between it and the sun then it will always be the ninth one.

A planet is required to have its own orbit while pluto's crosses neptune's.So pluto's not a planet

Pluto is a "Dwarf Planet" because it doesn't dominate its space.
