Is planet PLUTO still COUNTED in our solar system or REMOVED ?!


Question: Is planet PLUTO still COUNTED in our solar system or REMOVED !?
Answers:
REMOVED by the General Assembly of the International Astronomical Union
You see,
Pluto's official status as a planet has been a subject of controversy since at least 1992, when the first Kuiper Belt Object, (15760) 1992 QB1, was discovered!. Since then, further discoveries have intensified the debate!.

Allow me to further elaborate!. Let's break it down!.
Pluto (pronounced [?plu?to?] (help·info), from Latin: Plūto, Greek: Πλο?των), also designated 134340 Pluto, is the second-largest known dwarf planet in the Solar System (after Eris) and the tenth-largest body observed directly orbiting the Sun!. Originally classified as a planet, Pluto is now considered the largest member[6] of a distinct region called the Kuiper belt!. Like other members of the belt, it is composed primarily of rock and ice and is relatively small: approximately a fifth the mass of the Earth's moon and a third its volume!. It has a highly eccentric and highly inclined orbit!. The eccentricity takes it from 30 to 49 AU (4!.4—7!.4 billion km) from the Sun, causing Pluto to occasionally come closer to the Sun than Neptune!. Pluto and its largest moon, Charon, are often treated together as a binary system because the barycentre of their orbits does not lie within either body!.[7] The International Astronomical Union (IAU) has yet to formalise a definition for binary dwarf planets, and until it passes such a ruling, Charon is classified as a moon of Pluto!.[8] Pluto has two known smaller moons, Nix and Hydra, discovered in 2005!.[9]

From its discovery in 1930 until 2006, Pluto was counted as the Solar System's ninth planet!. In the late 20th and early 21st centuries, however, many objects similar to Pluto were discovered in the outer solar system, notably the scattered disc object Eris, which is 27% more massive than Pluto!.[10] On August 24, 2006 the IAU defined the term "planet" for the first time!. This definition excluded Pluto, which the IAU reclassified as a member of the new category of dwarf planets along with Eris and Ceres!.[11] After the reclassification, Pluto was added to the list of minor planets and given the number 134340!.[12][13]

The discovery of the Kuiper belt and Pluto's relation to it led many to question whether Pluto could be considered separately from others in its population!. In 2002, the KBO 50000 Quaoar was discovered, with a diameter of roughly 1,280 kilometres, about half that of Pluto!.[88] In 2004, the discoverers of 90377 Sedna placed an upper limit of 1,800 kilometres on its diameter, near Pluto's diameter of 2,320 kilometres!.[89] Just as Ceres eventually lost its planet status after the discovery of the other asteroids, so, it was argued, Pluto should be reclassified as one of the Kuiper belt objects!.

On July 29, 2005, the discovery of a new Trans-Neptunian object was announced!. Named Eris, it is now known to be slightly larger than Pluto!.[90] This was the largest object discovered in the solar system since Triton in 1846!. Its discoverers and the press initially called it the "tenth planet", although there was no official consensus at the time on whether to call it a planet!.[91] Others in the astronomical community considered the discovery the strongest argument for reclassifying Pluto as a minor planet!.[92]

The last remaining distinguishing features of Pluto were now its large moon, Charon, and its atmosphere!. These characteristics are probably not unique to Pluto: several other Trans-Neptunian objects have satellites, and Eris's spectrum suggests that its surface has a composition similar to Pluto's!.[93] It also possesses a moon, Dysnomia, discovered in September 2005!.

Museum and planetarium directors occasionally created controversy by omitting Pluto from planetary models of the solar system!. Some omissions were intentional; the Hayden Planetarium reopened after renovation in 2000 with a model of only eight planets!. The controversy made headlines at the time!.[94]

The debate came to a head in 2006 with an IAU resolution that created an official definition for the term "planet"!. According to this resolution, there are three main conditions for an object to be considered a 'planet':

The object must be in orbit around the Sun!.
The object must be massive enough to be a sphere by its own gravitational force!. More specifically, its own gravity should pull it into a shape of hydrostatic equilibrium!.
It must have cleared the neighbourhood around its orbit!.[95]
Pluto fails to meet the third condition, since its mass was only 0!.07 times that of the mass of the other objects in its orbit (Earth's mass, by contrast, is 1!.7 million times the remaining mass in its own orbit)!.[96][97] The IAU further resolved that Pluto be classified in the simultaneously created dwarf planet category, and that it act as prototype for a yet-to-be-named category of trans-Neptunian objects, in which it would be separately, but concurrently, classified!.

On September 13, 2006, the IAU included Pluto, Eris, and the Eridian moon Dysnomia in their Minor Planet Catalogue, giving them the official minor planet designations "(134340) Pluto", "(136199) Eris", and "(136199) Eris I Dysnomia"!.[98] If Pluto had been given a minor planet name upon its discovery, the number would have been a little over a thousand rather than over 100,000!. The first minor planet to be found after Pluto was 1164 Kobolda, a month later!.

There has been some resistance within the astronomical community toward the reclassification!.[99][100][101] Alan Stern, principal investigator with NASA's New Horizons mission to Pluto, has publicly derided the IAU resolution, stating that "the definition stinks, for technical reasons!."[102] Stern's current contention is that by the terms of the new definition Earth, Mars, Jupiter, and Neptune, all of which share their orbits with asteroids, would be excluded!.[103] His other claim is that because less than five percent of astronomers voted for it, the decision was not representative of the entire astronomical community!.[103] Marc W!. Buie of the Lowell observatory has voiced his opinion on the new definition on his website and is one of the petitioners against the definition!.[104] Others have supported the IAU!. Mike Brown, the astronomer who discovered Eris, said "through this whole crazy circus-like procedure, somehow the right answer was stumbled on!. It’s been a long time coming!. Science is self-correcting eventually, even when strong emotions are involved!."[105]


Children protest the reclassification of Pluto, police keep counter-protesters on a different corner!.Among the general public, reception is mixed!. Some have accepted the reclassification; others seek to overturn the decision with online petitions urging the IAU to consider reinstatement!. A resolution introduced by some members of the California state assembly light-heartedly denounces the IAU for "scientific heresy," among other crimes!.[106] The U!.S!. state of New Mexico's House of Representatives passed a resolution declaring that, in honour of Tombaugh, a longtime resident of that state, Pluto will always be considered a planet while in New Mexican skies, with March 13 being known as "Pluto Planet Day"!.[107] Some reject the change for sentimental reasons, citing that they have always known Pluto as a planet and will continue to do so regardless of the IAU decision!.[108] Others view this rejection as an attempt to bend the rules in order to keep the only planet discovered by an American classified as such!.[109]

The ongoing debate over the status of Pluto continues to be acknowledged by the Jet Propulsion Laboratory which, as recently as January 2008, continued to reference it on JPL Photojournal webpages dedicated to Pluto!.[110] Researchers on both sides of the debate will gather in August 2008 at Johns Hopkins University for a conference that includes back-to-back talks on the current IAU definition of a planet!.[111]Www@Enter-QA@Com

It's removed from our solar system as it is too far away too see, do research and so on!.!.!.
But in most of the schools, we did not remove it because it is still in our learning syllabus!.!.!.

So on and so on, many people still think it is counted in our solar system!.!.!.Www@Enter-QA@Com

Did you done it !? I think you forgot and still it's in universe!.Www@Enter-QA@Com
