"Planet" Pluto, is it fair it lost its status, & why do u think so?

Answer 1

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. i actually feel somewhat vindicated. i have known since i was about twelve that pluto did not have the physical and orbital characteristics of the major bodies in the solar system. later, after the discovery of hundreds of similar bodies in similar orbits, i knew this was inevitable.

(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".

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.

Answer 2

It is fair that pluto lost its status - it never really fitted neatly into the classification of other planets. Ceres (an asteroid, now considered a dwarf planet along with Pluto) used to be considered to be a planet for over 50 years until it was downgraded to an asteroid. Pluto lasted 76 years before being downgraded to a dwarf planet. If we allowed Pluto to be considered a major planet then we would end up with hundreds of "planets" orbiting the sun. At least with 8 major planets everyone can know what they are.

Answer 3

This isn't the first time planetary bodies have been re-classified. Cerres used to be a planet in the 1800's but got demoted, same thing with Pluto now ... I feel it should have been grandfathered in as a traditional planet, but now it will be know as a lesser planet. The need for it is because there are several objects in the ort belt that are larger than Pluto, so scientist are trying to make a unified classification for planets, it stinks, but that is how it is ... the first draft was going to make 12 planets in our solar system ...

Answer 4

its not on a planetary orbit, in fact it orbit is more like that of a comet, there are things out there that are bigger and have similar orbits, so if Pluto is classed as a planet so should some of them.

size wise there are moons of Saturn, or Jupiter, i can't remember which that are larger then Pluto, i don't think that this should count, as there are moons, not planets.

but the orbit thing i never thought of Pluto as a real planet, as its just a big chunk of ice

Answer 5

I think it is unfair. I am disappointed, personally. Let's examine the definition of the term 'planet':

plan‧et  /ˈplænɪt/ Pronunciation Key - Show Spelled Pronunciation[plan-it] Pronunciation Key - Show IPA Pronunciation

–noun 1. Astronomy. a. Also called major planet. any of the nine large heavenly bodies revolving about the sun and shining by reflected light: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, or Pluto in the order of their proximity to the sun.
b. a similar body revolving about a star other than the sun.
c. (formerly) a celestial body moving in the sky, as distinguished from a fixed star, applied also to the sun and moon.

2. Astrology. the sun, moon, Mercury, Venus, Mars, Jupiter, Saturn, Uranus, Neptune, or Pluto: considered sources of energy or consciousness in the interpretation of horoscopes.

All the books are going to have to change now. I think it's gratuitous.

Pluto is a planet. It revolves around the sun. It is a primary, and has three moons. Although Pluto's orbit is eccentric, and it revolves around the sun at a strange angle as compared to the ecliptic and the revolution paths of the other planets, it is still a planet.

I guess that they will have to now redefine what, precisely, a planet is.

Answer 6

Because it's been known as a planet for so long, I think it's only fair that it retains its status, although future generations who learn about the solar system could be taught of its 'actual' dwarf planet (or whatever it now is) status.

Answer 7

We don't have to worry about this bec. Pluto would removed from Solar System list but Pluto is still there. We only worried if Pluto is disappeared from the Universe.

Answer 8

Calling Pluto a planet was a bit like calling Hawaii a continent (Sorry Hawaii!).

Answer 9

Pluto, the most suitable planet to affix the heavenly pantheon, became the first to leave it. The status of Pluto were lower than communicate for your time, yet with the discovery of 2003 UB313, nicknamed Xena, the question became acute, for it possible had as a lot excellent as Pluto to be referred to as a planet. On August 24, 2006, the international Astronomical Union shocked the international by using balloting in a sparkling definition of planet, one which ought to exclude Pluto and produce the completed huge variety right down to eight. (There had before been been good hypothesis that the redefinition ought to carry the completed as a lot as twelve fairly of down.) Pluto changed into fairly categorized as a dwarf planet, alongside with Ceres and the aforementioned Xena. the important vast difference between a dwarf planet and the actual difficulty is that the dwarf variety has not cleared the realm of its orbital direction. This redefinition met with a wave of protests from those who wanted to make certain the 9th planet grandfathered in, such as yet not restricted to supporters of the previous due Clyde Tombaugh, who stumbled on Pluto in 1930. His widow, notwithstanding, suggested he ought to were accepting of the IAU's decision in view that "he turned right into a scientist" and understood that astronomers had to consider newly stumbled on gadgets in the Kuiper Belt (the position Pluto is placed). yet fighters of Pluto's demotion stay unconsoled and performance generated a thriving marketplace in T-shirts, mugs and different memorabilia. between the various slogans of this stream changed into one which performed on the mnemonic for the names of the erstwhile 9:

Answer 10

What i would like to know who are these people who decided Pluto was not a planet. I heard there was 100s of them who went to Prague and made this decision, who is paying them and how much did it cost
