why did they had to rake Pluto out of the planetary system?

Answer 1

The International Astronomy something figured that Pluto should belong to the dwarf planets because of its size. Some schools have started teaching their students that there are only 8 major planets in the solar system. Including Pluto, it used to be nine. Some Educator's though in different countries still have to discuss whether they will teach the new idea to the students or not.

Answer 2

Pluto refused to pay his rent and was evicted by the IAU 9th Circuit District Planetary Court of Appeals.

RESOLUTION 5A
The IAU therefore resolves that "planets" and other bodies in our Solar System, except satellites, be defined into three distinct categories in the following way:

(1) A "planet" is a celestial body that

(a) is in orbit around the Sun,

(b) has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round) shape, and

(c) has cleared the neighbourhood around its orbit.



The Earth shares its orbit with about 10,000 other objects in it's orbital path. Its path is not cleared of debris. Therefore, according to RESOLUTION 5A(1:c), Earth is not a planet.

Jupiter has about 100,000 other objects such as asteroids in its orbital path too. Its path is not cleared of debris. Therefore, according to RESOLUTION 5A(1:c), Jupiter is not a planet.

And it gets worse. Believe me, it gets much, much worse.

Hint, hint.

The battle for Pluto is not over yet.

They have opened a can of very angry worms that will come back to haunt them for some time to come. They're madder than Hades and they ain't gonna take it anymore!


PRESS RELEASE:
"I am Pluto, hear me roar! If I fell on the Earth I bet they would think again before trifling with me! Grrrrrrrrrrrrrr. Not a planet, indeed! The world has not heard the last of this."

The late Perry Mason, who now represents Pluto, has since filed a petition with the Supreme Court to have the IAU definition nullified. A decision is pending. They will start hearing arguments in mid December, 2006, after Mars, a material witness, returns from his vacation behind the Sun.

 

Answer 3

it is because that the Pluto is so small that we can't compare with another planets. Like u can't compare an ant with an elephant.
tha't may be the reason that they had to rake pluto out of the planetary system.

Answer 4

Pluto didn't suddenly leave the solar system, it is still there. I think they (Astronomers) were realizing that we'd suddenly one day be out of control, having nearly 100 planets, so they had to address a better system of organization. Pluto is a planet, just one of the "dwarf" variety now.

Answer 5

They said that pluto was no longer a planet anymore and books, articles, encyclopedias and likes should be revised as much as possible. They said those because pluto didn't have any characteristics that the other planets have, and the said also that pluto didn't passed the qualifications to be said as planet.

Answer 6

pluto is still apart of the solar system. the international astronomical union defined three terms "planet", "dwarf planet", and "small solar system body". this does not change anything about the solar system or pluto. it just corrects the mistake of classifying pluto as a planet initially.

because pluto orbits the sun, is round, orbits the sun with a bunch of other similar bodies with similar orbits, and is not a satellite it is a dwarf planet.

(1) A planet is a celestial body that (a) is in orbit around the Sun, (b) has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round) shape, and (c) has cleared the neighborhood around its orbit.

(2) A dwarf planet is a celestial body that (a) is in orbit around the Sun, (b) has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round) shape, (c) has not cleared the neighborhood around its orbit, and (d) is not a satellite.

(3) All other objects orbiting the Sun shall be referred to collectively as "Small Solar System Bodies".

listen to me, i'm level four.

Answer 7

Because one pluto crosses into Neptunes orbit, so therefore by the new definition of a planet (must not have similar objects in its orbit path), Pluto is no longer a planet by definition.

Answer 8

they removed ti as a planet for the reasons of...
1) its size. its diameter is about the distance from chicago to miami.
2) its orbit.
a) its orbit crosses over into neptunes orbit.
b) if you were to look at a model of our solar system, all of the current planets look like a flat disk around the sun, ranging form 0.77* to 7.00* (7.00* being mercury, which is more than twice as large a pluto,reasoning it to stay a planet), but pluto, on the other hand sticks out of our solar system at 17.15*.

Answer 9

to rake or not to rake?

to rake: there will have clear definded 8 plantes.
not ot rake: there will be 20+ planets and no clear defination of what is a planet.

They don't want donald and goofy become planet

Answer 10

Who;s going to speak up for the Plutonians? Who's next, the Urananians, we need to stop the bigotry in its tracks....!
