Um. They (the scientists) declare that it isn't a planet, and it suddenly isn't a planet. The End.

they declared it didn't meet the new criteria used to define a what a planet is.
"According to the new definition, a full-fledged planet is an object that orbits the sun and is large enough to have become round due to the force of its own gravity. In addition, a planet has to dominate the neighborhood around its orbit.
Pluto has been demoted because it does not dominate its neighborhood. Charon, its large "moon," is only about half the size of Pluto, while all the true planets are far larger than their moons.
In addition, bodies that dominate their neighborhoods, "sweep up" asteroids, comets, and other debris, clearing a path along their orbits. By contrast, Pluto's orbit is somewhat untidy."
It's now considered a dwarf planet.

Also, Pluto does not have a circular orbit around the sun, it is more of an oval and at some points in its orbit is closer to the sun than Neptune, for that reason it is not classied as big enough to command its own orbit and be a fully fledged planet. Its still in the milky way though, that has not changed

After a few thousand years, the astronomical community is finally deciding on a firm definition for 'planet'.
The designation of Pluto is now "dwarf planet", which leads one to assume there is a minimal size requirement that is less inclusive as "large enough to become spherical via it's own gravity".
The problem with Pluto, I say, is not just it's size or insane orbit, but also it's unusual dance with Charon.

A rose by any other name would smell as sweet.
Does it really matter if we call pluto a planet or not?
The label doesn't change the nature of the subject.
And it won't inhibit scientific inquiry.
What is the big deal?

1) use spell check
2) They did not exclude from Milky Way since Milky Way is the galaxy we live in...Pluto was downgraded from Planet status to Dwarf Planet status in an attempt to codify the classification of stellar objects

Your question doesn't make any sense. Pluto is now classified as a "dwarf planet". What does that have to do with the Milky Way?

They are removing the planet status from Jupiter (from our solar system) because it is too small to be considered a planet. I don't know who determines the size or what it is, but that's the gist of it.

Pluto is now one of many asteroids in a new asteroid belt found at the outer limits of our solar system
