why is the pluto not a planet of our solar system anymore?

Answer 1

IT IS TO SMALL TO BE A PLANET

Answer 2

Pluto, the last planet to join the heavenly pantheon, became the first to leave it. The status of Pluto had been under discussion for some time, but with the discovery of 2003 UB313, nicknamed Xena, the question became acute, for it seemingly had as much right as Pluto to be called a planet.

On August 24, 2006, the International Astronomical Union surprised the world by voting in a new definition of planet, one that would exclude Pluto and bring the total number down to eight. (There had previously been been strong speculation that the redefinition would bring the total up to 12 instead of down.)

Pluto was instead classified as a dwarf planet, along with Ceres and the aforementioned Xena. The main difference between a dwarf planet and the real thing is that the dwarf variety has not cleared the area of its orbital path.

This redefinition met with a wave of protests from those who wanted to see the ninth planet grandfathered in, including but not limited to supporters of the late Clyde Tombaugh, who discovered Pluto in 1930. His widow, however, said he would have been accepting of the IAU's decision since "he was a scientist" and understood that astronomers had to take into account newly discovered objects in the Kuiper Belt (where Pluto is located).

Answer 3

Well, pluto is mark as a planet first when it was discovered orbit around the sun, however we don't know much so we claim it planet. Scientist already research about Pluto after a launch to there, that Pluto recieved less sunlight so it's cold and small like asteroid or drawf planet. Scientist deduced it's not a planet but a leftover inside solar system that has been dragged into orbit, so they classified it under drawf planets.

That's all I know about Pluto.

Answer 4

LOL!! next you'd be telling us that astrology is misguided because the Earth isn't the middle of the universe. It amazes me at the same time as human beings declare an pastime in astrology yet fail to carry close it really is maximum hassle-free premise. Astrology is a language of symbols. which contain when we are saying Mercury is retrograde. Mercury isn't easily shifting backwards. It only looks and is symbolic on the purpose of the psyche. Pluto is an important portion of our psyche and continually will be no count what all of us in a junior extreme technology classification says. If some thing Pluto's declassification symbolizes a denial of those elements human beings that are governed by skill of Pluto. it really is a appealing preamble to Pluto getting into Capricorn the position it really is going to extremely shake up society usually. It pertains to Jung's theory of the Shadow. What we deny about ourselves will reek havok in our lives. Did I lose you? So sorry. possibly you will get truly one of your instructor to describe it for you. smile

Answer 5

We've found rocks further out there that are larger than Pluto. So, if we included Pluto, we'd have to include at least 3 more, bringing the total to 12.

Answer 6

Because it didn't meet the rule of the IAU saying: a planet must dominate and clear the neighbourhood around it's orbit.
Because it didn't meet that rule, it is now classified as a minor planet.

Answer 7

I believe it is because scientists think that Pluto is just another rock from a large ring called the Kuiper Belt. It is just abnormally larger than most of the other clumps of ice in that belt.

Answer 8

It was too small
It's orbit was peculiar
If it was allowed in, then plenty more would've been in
and then our solar system would be enormous and impossibly complex

Answer 9

Because the universe is not as simple as you'd like to believe.

Answer 10

God, will this question never go away? Many months ago 500,000,000,000,000 other people started asking this stupid question. Look them up.
