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

because those scienctists think planets should be big. They are also gonna strip neptune too!
I am very unhappy that it lost its status as a planet.. It is not a dwarf planet.. Thus.. it is still a planet.. or are those people going to call it now a star... a comet. or even an asteroid? Do not worry Pluto. to me you are still a planet.
Don't worry too much - I hear Pluto is going to appeal
No i think that becase plouto has a moon It is a planet i dont care what those science freaks say
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.
Because one of its moons is double the size of it and it travels in a different orbit than the other planets, and no they will not strip pluto either.
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
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.
The pinheads at the observatory fiddled with the definition until they could kick Pluto out of the club. If Galileo had found Pluto this would not even be a discussion.
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 .
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.
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
Fair, It was always felt to too small to be a fully-fledged planet.
Calling Pluto a planet was a bit like calling Hawaii a continent (Sorry Hawaii!).
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.
What does Mickey say about it?
