Is Pluto still a planet?

Question

My teacher says no but i so not know.

Answer 1

At an international conference of astronomers last year, the decision was made to demote Pluto from planet to what is called a "dwarf planet". This was decided because of Pluto's size (they have found at least one object larger than Pluto orbiting the sun farther out) and for a number of other reasons.
The solar system is now (in order from the sun):
Mercury
Venus
Earth
Mars
Ceres (dwarf planet located in the asteroid belt)
Jupiter
Saturn
Uranus
Neptune
Pluto (dwarf planet)
Eris (dwarf planet)

Pluto and Eris are both called "Kuiper Belt Objects" because they are simply the largest objects that have been seen so far in the Kuiper Belt (a belt of small objects orbiting beyond Neptune, similar to the asteriod belt that orbits between Mars and Jupiter).

Answer 2

Some of the so called scientific people say, "NO" and some say, "Yes". The supposed world of academic is staying with the ones that say, "No". Why? Because they are teachers. Me personally I say it's a plant why. Well it's round like a planet, it orbits like a planet and it's in our solar system like a planet. So therefore, it is a planet and religion has nothing to do with it like some think. They just needed an excuse.
I was taught that if it looks like a duck, quacks like a duck and walks like a duck well then it must be a duck.

So in your heart if you think and believe that Pluto is a planet. Then go right a head. Just because a person has a degree, it does not make them right all of the time. What I would like to know is how much money those people sent on deciding the question.

Answer 3

Not anymore because the planet didn't meet the third requirement.
The astrolonmer realized that Pluto circular is perpendicular to the other planets. Pluto movement is not moving in the same circular movement as compared to the other planets. As a result, Pluto is no longer classified as a planet. According to the McGriffin Laboratory (Observation) of Los Angeles, California

http://en.wikipedia.org/wiki/Planet

Pluto is a dwarf planet. It is small and there are many like it on similar orbits.

The same thing happened in the 19th century when Ceres, Pallas and Vesta were newly discovered planets. As time went on (and as instruments got better) astronomers were discovering other small, similar bodies on similar orbits. Therefore, Ceres (and others) were demoted from planets to "minor planets" -- also known as asteroids.

So, they are still "planets" in the sense that a boy is a "little man" (the boy is a human, not a horse or a kangaroo). They share some features of planets, but not all of them.

Answer 5

Not a planet.

Late last year it was decided that Pluto should be reclassified as a "planetoid".

There are several reasons for this, but primarily it was the size of the planet and its bizarre orbit (Pluto's orbit actually means that sometimes it is closer the the sun than Neptune).

Answer 6

i heard scientists have a theory that pluto may not be a planet but a star of neptune or there's another planet with multiple stars after pluto

Answer 7

Some say "yes." Some say "No." The very definition of "planet" seems to have changed over the years. My opinion? It's still a planet.

Answer 8

i'm in Kansas, and it was a Kansan that discovered Pluto, (and named it after a Disney(another Kansan, or was it Missourrian? same thing) caracter...
Pluto always was and always will be a planet, of some sort. (even though it isn't a planet, i don't think that changes the cosmos any)

Answer 9

according to the modern definition of a planet, Pluto is not a planet anymore but in remembrance of the former planet the word "plutoic" or "plutonic", if i am not mistaken, is coined

Answer 10

Every body is saying no but some religious beliefs are trying to stop that. A planet thtat was found is called Eris by the way.
