is pluto a satellite?how can u prove?what mistake does old scientists had done when they rate it as a planet?

Answer 1

Try that question in English. If I understood your question, I would have to question my own sanity.

Answer 2

Pluto is not a satellite. According to the latest nomenclature it is a dwarf planet. Earlier scientists did not know that there were many (at least 12) more heavenly bodies comparable to the size of Pluto orbiting the sun. Thus they classified Pluto as a planet. But due to advances in astronomy it is now known that:
1. Pluto has an extremely eccentric orbit.
2. Pluto is not large enough so that its gravitational force can clear bodies in its immediate neighbourhood.
Due to these reasons it has recently been decided to change the definition of planet which satisfies these criteria. Under the new rules Pluto is no longer a planet. It is merely a change in nomenclature and actually doesn't mean anything.

Answer 3

It is just a question of nomenclature. There was no mistake. Scientists decided that Pluto was a planet when it was discovered because it orbited the sun. Recently, many more objects orbiting the sun were discovered and the asteroid belt has been known about for many years. So everyone had to decide if these other objects were planets or not, so they had to decide exactly what a planet is.

After a bit of thought, they decided that they didn't want there to suddenly be 12 planets, with so many new ones expected to be discovered too, when most of them are far out tiny rocks the size of the moon that don't matter at all. Eventually they decided that Pluto was one of these far out tiny rocks too. So they decided that all of these less significant bodies would be dwarf planets, and the number of 'real' planets was changed to eight.

There was no mistake, they just thought a change in the definition of planet would keep things simpler. Instead of an ever-changing number of discovered planets, there are always going to be eight, and teachers won't have to bother teaching about planets that aren't important enough to even have names. They can wrap up the tour of the solar system with 'and there are a bunch of dwarf planets out there, such as Pluto . . ." and not need to know much about them.

Answer 4

Oops yes it is...

Pluto is a satellite of the Sun! The first rule for being a Dwarf Planet. But it's not a satellite of a Planet (sometimes shown as the 4th rule for Dwarf Planets).

You can prove it with observation and simple math, or even logic...

They mistook it for a planet because they didn't realize how many Kuiper Belt objects there were and how varied in size they were. They thought "ooh a kind of big thing!" and called it a planet because they didn't really have a set definition. Now we know it's a rather ordinary comet (well, extraordinary enough to be called a Dwarf Planet as well) and have a better view of our solar system and planets of other solar systems, not to mention how they form, so we don't call it that anymore.

Answer 5

pluto is not a satellite. it is a planet. it is the 9th planet in the solar system. recently the scientists discovered 3 new planets. i m not sure but 1 of them is the moon of pluto. the newly discovered planets r different from the other planets but r quite similar to pluto. pluto and the 3 planets r now being called plutons. the scientists have officially changed the definition of planets.due to this discovery.

Answer 6

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 twelve 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.

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".

Answer 7

pluto was actually discovered in 1930s n it was given a planet status but now bcoz of the advanced telescopes the scientists have discoverd much more bodies than pluto which r bigger than pluto n hence the status of pluto being a planet is lost now

Answer 8

Pluto is not satellite.because it rotates the sun and not another planet.they mistook Pluto with their primitive equipment as much as 5times the earth

Answer 9

Come on man,use your brain!
A stupid meeting in eastern europe between a bunch of nerds and they change history?It's obvious that these clowns have nothing better to do and are trying to create some action in astronomy so that their budgets/funding will not be cut.This is a step backward for mankind!And i can't believe that there is not much opposition to the declassification of pluto.Pluto to me will always be a planet,screw these assholes.They don't know ****!

Answer 10

basically pluto and its moon charon according to earlier definition were planet and sattelite but the centre around which they rotate as a system is outside both of them so none of them can qualify as planet
but in case of moon earth system the centre of rotation is in the earth so earth --> planet
moon-->sattelite

Answer 11

If Pluto is a satellite, what is it a satellite of??? (other than the sun)........
