Is it true that Pluto is no longer classified as a planet?

Question

I heard recently Nasa think its more like a moon. (i think)

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

pluto does orbit the sun, is ball-shaped and is not a satellite, but it does not have an isolated orbit (a bunch of other similar bodies have similar orbits.) 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 the sun between the orbits of mars and jupiter and thought it was a planet. astronomers finally stopped classifying them as planets after they found several other bodies with similar orbits, and no one 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 2

Yes. Pluto is no longer a Planet. It is now categorized in the group of Dwarf Planets. Officially the Solar System now consists of 8 planets and 3 dwarf planets - Pluto, Eris (after Pluto) and Ceres (between Mars and Jupiter).

Answer 3

Pluto is now classified as a Dwarf planet...I think it should still be classifyed a planet though, because it still rotates around the sun.

Answer 4

confident pluto is not a planet using fact the dwarf planet can not avert getting hit via comets and asteroids and likewise does not circle the sunlight like something of the planets in our image voltaic equipment and is not has great has something of the planets its a competent factor it grew to become into demoted has there is no could desire to look at that factor has it extremely is in basic terms a huge ice ball which could on no account help life till you have alot of gas pipe strains lol even then it could be not easy to stay there if its even available desire this facilitates i watch nasa television alot

Answer 5

yes they decided it was too small to be called a planet
but they recently (two years ago) found so new things orbiting the sun which might just be big enough to be called planets (they are around the size of Ploto) some one is a bit bigger though

Answer 6

That little ice cube is smaller than our moon, it's only a minor planet, took the scientist this long to figure out. Now lets see how long it'll take um' to see that the planets getting hotter.

Answer 7

Yes. But don't worry, Pluto doesn't care.

Answer 8

Yes. It was dubbed not a planet about three months ago.

Answer 9

Yes to bad for the cartoon reputation to get out ther now lol.

Answer 10

The sience ppl say its too small to be a planet so its a star know:/
