Pluto , pluto ..... Where are you ?

Question

Where is pluto ? It has been removed , from the solar system and lost in the dark dark space . Do you think this is fair?

Answer 1

Good question
Pluto is out there somwhere after neptune . May be it is removed from the planet status but not from the solar system , It is in the status of a dwarf planet and it isn't lost and It isn't fair but this isn't the first planet to be removed from the planet status but ceres was once aplanet in the ancient times it was in the planetery status for 5 decades and was removed by the same scientist/astronaut who found it , he stated he was wrong on his prediction and declared it was an asteroids which was floating the space which looked to him as a planet . It was said be in the middle of mars and jupiter .

on 24 august 2006, the international astronomical union reclassified pluto.

pluto does orbit the sun, is ball-shaped, does not have an isolated orbit (a bunch of other similar bodies have similar orbits.), and is not a satellite 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 soon found several others and finally stopped classifying them as planets. no on 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

Answer 3

The International Astronomical Union decided that Pluto was no longer a planet. The reason is that while Pluto is round, orbits the sun, and has three moons, it has not cleared (via gravity) its own orbit of debris. Instead, they decided to classify it as a "dwarf planet".

See the details below.

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" [footnote 1] 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.

(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 [footnote 2] , (c) has not cleared the neighbourhood around its orbit, and (d) is not a satellite.

(3) All other objects [footnote 3] except satellites orbiting the Sun shall be referred to collectively as "Small Solar-System Bodies".


Footnote 1: The eight "planets" are: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.

Footnote 2: An IAU process will be established to assign borderline objects into either dwarf planet and other categories.

Footnote 3: These currently include most of the Solar System asteroids, most Trans-Neptunian Objects (TNOs), comets, and other small bodies.

RESOLUTION 6A
The IAU further resolves:

Pluto is a "dwarf planet" by the above definition and is recognized as the prototype of a new category of trans-Neptunian objects.

Answer 4

Pluto is no longer considered a planet. It never was a planet in the first place. Pluto is still part of the solar system.

Answer 5

Pluto has been removed from the list of PLANETS of our SOLAR SYSTEM.

Pluto is still present in the solar system. And it is removed from the list of planets because it doesn't passes through the new definition of the "Planet".

Answer 6

Ok sweety here is the fact pluto was considred a planet becaue of certain reasons which u know .But when it was proved that those properties r not followed they had 2 remove it

Answer 7

If you want to count Pluto as a planet then there are at least 3 more in the Oort cloud and probably hundreds more that haven't been seen yet. It's an ice ball, not a planet.

Answer 8

It is still there, but downgraded to "dwarf planet". Needless to say, it is sulking, hiding in its room and lying in bed all day.

I don;t blame Pluto, as only about 220 members of the IAU made that decision. Personally, I think it was a plot by Neptune to gain some status

Answer 9

We have been fair to pluto for a long time, now its time to move it out of family as it does not abeys family rule and regulations.

Answer 10

Pluto has been declared to be immature, and has been sent to sit at the "little planets" table.
