It would be really funny if a decision by the International Astronomical Union could actually affect the crazy ideas of astrologers. That alone is a reason to demote Pluto.

No, this is a dwarf planet, including 5 different products in the image voltaic gadget. Which even have moons. To be a planet: a million. Orbit around a megastar (and not yet another planet). 2. Be in hydrostatic equilibrium (meaning the exterior of the planet is around or egg formed, counting on the rotation of the planet and not as an occasion looking like a extensive potatoe, it is defining the minimum mass for a planet from an astronomers sight) 3. Have cleared the orbital community of alternative products (meaning, have adequate gravity to dominate this area). All 8 planets are each ninety% of the mass of their orbital area, Pluto isn't even 15%. Pluto have been given degraded, because of the fact this is a factor of a extensive team of goods, referred to as Plutinos, that are orbiting around the solar with sort of an identical orbit era as Pluto - suggesting that they formed by making use of a collision in early history. Pluto has the 1st 2 attributes of a planet, yet no longer the 0.33, it is the reason this is a Dwarf Planet. If Pluto might purely have had the 1st characteristic, it could have been an asteroid in the present day - even asteroids could have moons BTW (Ida & Dactyl as an occasion).

the only answer to this question is:
because pluto orbits the sun, is round, does not have an isolated orbit (a bunch of other similar bodies have similar orbits.), and is not a satellite it is a dwarf planet.
because mercury, venus, earth, mars, jupiter, saturn, uranus, and neptune are round and orbit the sun in isolated orbits they are planets.
this does not change anything about the solar system or pluto. it just corrects the mistake of classifying pluto as a planet initially
i have been waiting for this since i was about twelve. i feel somewhat satisfied. this was the right thing to do, believe me. i don't understand why so many are having such a problem with this. i don't know how long this will drag on tho. many planetary scientists are not satisfied with the definition because it is not rigorous enough.
i have decided to add that the answer given by "me..........anee" is mine, with a few words added, copied from a previous answer. i felt pretty pleased and amused when i saw it.

The reason that Pluto was excluded is that it's just one Kuiper Belt Object (KBO) of many that we've now seen. Either there are eight planets or there are more (probably a lot more) than nine. Nine is not logical no matter what. It's not fair to favor Pluto over other KBOs, some of which are probably larger. And it's better to treat KBOs like asteroids, which are also not considered planets. That way we have eight well defined planets, thousands of asteroids, and thousands of KBOs, instead of trying to pick some special asteroids and some special KBOs out and call them planets. What could make them special, that people would not argue endlessly about?

The earth is only one planet in our solar system.
Our solar system has a star which is our sun.
The sun is just of the stars in our galaxy which is the milky way.
And there are other galaxies in space.
We human beings are totally insignificant in the universe. So it doesnt matter at all what we say or do. So pluto is no longer considered a planet by humans. Big deal!! How can it possibly affect anything on the universal scale???

Hi. Astrology aside, the real problem is that the more we (humankind) learn the more we realize we do NOT know. Prior to Pluto's discovery in the 1930s we were perfectly happy to have eight planets. Now everyone and her second cousin is emotional about the reclassification of a ball of rock and ice. Have any of these nice folks ever SEEN Pluto? I have. And I'm not emotional about science adjusting its nomenclature based on new knowledge. If we don't want to know anymore then stop looking? No.

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 have known since i was about ten(as i luv astronomy i keep reading books n factz bout it) that pluto does not have the physical and orbital characteristics that fit the pattern set by the major bodies in the solar system, and later, after the discovery of hundreds of other similar bodies with similar orbits, i knew this was inevitable. this was the right thing to do, believe me ppl really.
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".

Pluto is a "Dwarf Planet" This is a classification given to bodies that revolve the sun but are below a certain size. There are a few of them in the solar system and one of them is actually larger than Pluto.

Well I haven't reviewed the scientific reasoning behind why Pluto was demoted,but I think that if a planet is defined by one having a moon in that case Pluto is a planet.

I guess it's a matter of science vs. philosophy or religion...but according to Scientists the poor thing has been stripped of it's planet status and referred to, demeaningly, as a mere "hunk of ice." Poor lil Pluto!!
After thought... I think the peeps that make maps of the solar system paid the scientists to demote Pluto just so they could pump up their business by making new maps...ummmmmm??
