on 24 august 2006, the international astronomical union reclassified pluto.
pluto does orbit the sun, is ball-shaped and is not a satellite, but it does not have an isolated orbit (a bunch of other similar bodies have similar orbits.) so it is not a planet.
i have been waiting for this since i was about ten when i learned that pluto didn't fit the pattern set by the major bodies in the solar system so it was an anomaly. it just felt "out of place". now that astronomers have found hundreds of other bodies with similar orbits, classifying "134340 pluto" as a planet is even more irrational. i feel somewhat satisfied, but i don't know how long this will drag on tho. many planetary astronomers are satisfied that the definition is rigorous enuf. i can accept that the definition is flawed, but i can not accept that "134340 pluto" is a planet.
this was the right thing to do, believe me. this does not change anything about pluto or the solar system. this just corrects the mistake of classifying pluto as a planet initially.
this same thing happened has happened before. in 1800, an astronomer found a body orbiting between the orbits of mars and jupiter and thought it was a planet. astronomers finally stopped classifying them as planets after they found several other bodies with similar orbits, and no one thinks ceres, pallas, juno, and vesta are planets today.
many astronomers consider pluto and charon to be a binary system, but two small bodies orbit that system. they are called nix and hydra.
incidentally, "134340 pluto" was never a moon of neptune. neptune did capture triton. this is why triton has a retrograde orbit

No. Pluto has just been demoted.The celestial body, long known as one of the nine planets of the solar system, will now be considered a "dwarf planet," the General Assembly of the 2006 International Astronomical Union ruled in a vote Thursday in Prague, Czech Republic.
Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune will be defined as "classical planets."

Pluto is now considered as a dwarf planet and designated a number 134340 pluto. The IAU had passed certain resolutions for defining a planet. Amongst many, pluto has not cleared it orbit and is inflenced by the gravity of Neptune. Further its inclined at 17.1 degrees. Many of these clauses went against pluto and it was voted out.

"Pluto in the Minor Planet Center catalogue, is the second-largest known dwarf planet in the solar system."
-Wikipedia
"After years of wrangling and a week of bitter debate, astronomers voted on a sweeping reclassification of the solar system. In what many of them described as a triumph of science over sentiment, Pluto was demoted to the status of a “dwarf planet.”"
-NY Times

It's a dwarf planet but it's still there in the milky way but not considered as a planet under the solar system milky way.

scientists says that pluto is now no longer be considered as the ninth planet because it does rotate in an oval shape and not as in a circle as the other planets do and it is very small from the other planets and therefore ithas now been called as an asteroid but it's name will be still called as pluto.

Depends on who you ask.
Officially, no. But I like Pluto and still consider it a planet.
BTW, the Milky Way is the galaxy that our Solar System is located in.

it would be 13 planets (you counted Pluto the two as a planet and dwarf planet). however the element is, there might nicely be greater dwarf planets to be stumbled on, so the type will shop icreasing. i'm able to ensure why the astronomers desperate to entice the line at Neptune. previous Neptune lies portion of many Pluto-sized products that are in actuality the "left-overs" from the formation of the photograph voltaic equipment.
