what is diffrence between planets and plutons?

Question

and what are name of the three new planets

Answer 1

The word “planet” comes from the Greek word for “wanderer”. But today hosts of newly discovered large objects in the outer regions of our Solar System present a challenge to our historically based definition of a “planet”.

Plutons are distinguished from classical planets in that they reside in orbits around the Sun that take longer than 200 years to complete (i.e. they orbit beyond Neptune). Plutons typically have orbits that are highly tilted with respect to the classical planets (technically referred to as a large orbital inclination). Plutons also typically have orbits that are far from being perfectly circular (technically referred to as having a large orbital eccentricity). All of these distinguishing characteristics for plutons are scientifically interesting in that they suggest a different origin from the classical planets.

Our Solar System will include 12 planets, with more to come: eight classical planets that dominate the system, three planets in a new and growing category of “plutons” – Pluto-like objects – and Ceres. Pluto remains a planet and is the prototype for the new category of “plutons.

The new definition would mean there are 12, not nine planets, and more could be added to the list in the future.

They include eight "classic" planets - Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune - Ceres, currently considered an asteroid, and three "plutons," one of which is Pluto.

The other plutons are Charon, currently described as a moon of Pluto, and the newly-discovered object 2003 UB313, which has not been named officially, but is nicknamed Xena.

Ceres is the largest object in the asteroid belt between Mars and Jupiter, and like a planet is spherical in shape.

PLANETS
A planet is generally considered to be a relatively large mass of accreted matter in orbit around a star. As yet there is no formal definition for the term, but a proposed resolution by the IAU would define it as follows: A planet is a body that directly orbits a star and is large enough for its gravitational forces to overcome rigid body forces to form a round or near-round shape. However, a body that is massive enough to undergo the fusion of hydrogen in its core is considered a star and not a planet, although there remains debate over those objects sustaining deuterium fusion. Also, if the object orbits a planet (i.e the centre of mass it orbits lies within a planet's surface) then it would not qualify under the new definition.

Based on historical consensus, the International Astronomical Union (IAU) lists nine planets in our solar system, though this number will change to at least twelve should the IAU general assembly approve the proposed official definition in a vote scheduled for August 24th, 2006.

Traditionally, a distinction has been drawn between planets proper, and large asteroids (which have been called minor planets). However, the dividing line between these bodies has become increasingly problematic due to the discovery of bodies in the outer solar system (Kuiper belt) that approach, and in at least one case exceed, the size of the smallest traditional planets

PLUTON

Earlier in the process of coming to a planetary definition, plutonian objects had been described using the name pluton. The definition of a pluton was given in greater detail, being a planet whose orbit took more than 200 Julian years to complete and whose orbit was more highly inclined and elliptical than a traditional planetary orbit.[1] This definition would likely have included any new planet discovered beyond the orbit of Neptune.

There was some controversy surrounding the choice of the word 'pluton' due to potential confusion with the geological term of the same name.[2] In addition, "Pluton" is the translation of Pluto in several languages.[1]

In the introduction to the final form of its proposal the IAU stated that the Merriam-Webster dictionary defined 'plutonian' as, "of, relating to, or characteristic of Pluto or the lower world." Thus the difficulties previously experienced could be avoided through the choice of a simple and literal term.

Answer 3

A star is an object with enough mass to create a core density and temperature high enough to create fusion of hydrogen nuclei. That's all there is to it. The synthesis of Helium from Hydrogen is the key to the distinction. The lower limit of the mass of an object which can be a star is believed to be 1/24 the mass of the sun. Below this threshold it cannot produce fusion and doesn't shine like a star and is known as a brown dwarf. Jupiter could, if you really stretch your mind, be considered to be a very small brown dwarf. I forget the exact numbers but to become a star, Jupiter would need to be somewhere between 10 and 100 times more massive. Yes thats a big range I know but I'm having to think back a few years. Gas giant planets and stars are not that dissimilar in their ingredients. A few percent that's all. The difference is because the star forms first. Curiously, the CV group of chondritic meteorites, are almost identical in their ingredients to stars, just minus the hydrogen and helium. CV carbonaceous chondrites are believed to be among the first things to be formed when the solar system formed. It's worth pointing out that even the seemingly unrelated rocky, terrestrial planets will have formed from this stuff too, so everything is made up of more or less the same stuff. The ultimate decider as to your fate is your mass. Do you have enough to create nuclear fusion?

Answer 4

Planets have a fixed orbits whereas plutons have some periodical changes in their orbit's trajectory. This is a result of being weakly influenced by the suns gravity and being closer to other large mass planets (the outer planets). Basically any large objects coming from the oort clouds can be classified in this category.

Answer 5

Planet : It is a celestical body which has sufficient mass for its self gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium,nearly round shape,and it is orbit around a star and either a star nor stallite of a planet.

Pluton:They are classical planets in that they reside in orbits around the Sun that tale longer than 200 years to complete.Plutons have orbits that are highly titlted with respect to the classical planets.Plutons also have orbits that are far from being perfectly circular.

In galaxy they already found Mercury ,Venus,Earth.Mars,Jupiter Saturn,Uranius,Neptune and Pluto.Now they found three new planets they are Ceres,Charon( which is pluto companion)and 2003 UB.

Answer 6

A Pluton is ..

1 ..A body of igneous rock formed beneath the surface of the earth by consolidation of magma.

2..large mass of intrusive igneous rock believed to have solidified deep within the earth .



A Planet is .. any of the nine large celestial bodies in the solar system that revolve around the sun and shine by reflected light; Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto in order of their proximity to the sun; viewed from the constellation Hercules, all the planets rotate around the sun in a counterclockwise direction

Answer 7

Plutons (Pluto-like objects) are smaller Trans-Neptunian Objects (TNOs), with larger orbits taking a long time to complete and therefore long "years"

The three bodies now being accorded planetary status have NOT just been discovered, They are Ceres (discovered 1801), "Xena" (discovered 2003) and Charon (discovered 1978). "Xena" (a nickname only) may get renamed after a Roman deity, as e,g, Persephone.

Answer 8

I believe the term "pluton" is gone with the wind..
I believe the new term is now going to be "minor planets"..
Pluto and its moon may end up being two of these minor planets.

Answer 9

What the hell are plutons!?
