pLuTo is a Planet or Satellite

>>>Nowadays, we have a old discussion about Pluto!
Is Pluto a planet or a satellite to you!!!

1)Pluto is smaller than the other planets and its' diameter is 2300 km.
2)Smaller than the moon..
3)About dimension Pluto quashes the planet series..
4)Pluto's and Neptun's orbits are cuttin each other...
5)If we look other planets ; Plutos Moon Charon is further big than the others...

Yes the reasons are listed here ...
Whats ur ideas???


Thanqs for ur interest..

Because of the constant detection of many other KBOs with masses upwards of half that of Pluto, it seems likely that Pluto is better described as the King of Kupier Belt Objects, rather than as a planet.

The IAU says it is a planet. That precedence rules.

not to sound stupid but what IS a planet?

we all know earth and mars ect r planets but what makes them a planet?

the composite? size? water?

 

That's the problem -- there is no specific definition. The IAU declares Pluto a planet; subsequent research indicates it's only a bit larger than many other similar bodies. Who's to say?

Warren God knows Pluto is a planet or not

A couple of years ago a couple of crapmonkeys said "We're re-classifying Pluto, it's not a planet any more". Then, after that, the IAU said "Yes it is a planet."

 

if we turn the question around to - what is a moon, then I'd say that it's a space object that is orbiting around other space object but that object must not be the central star.

Pluto is orbiting around our central star therefore it's a planet. Of course by my definition it could also be a comet (but it is too slow) or a meteorite (but it's too big for a meteorite)

 

There are a lot of things that orbit stars, not the least of which are planets and comets. How about asteroids? Planetesimals? Kupier belt objects? Dust grains?

And Pluto cannot be classified as a meteorite, by definition, unless it crashes into the earth and hits its surface.

Pluto&Neptun orbits are cutting each other.Thats ok.But im having difficulties understanding this..Because my hipotez is "Pluto and Neptun gonna crash and explode" is that possible..Tell me your ideas

sorry - I mixed it with the asteroid

pity here is no mousehole to hide in

I think that here we must look on the size of an object.
Let's say that if it's diameter is bigger than 1000km
It may be 1000, it may be 1002. Don't know really, but the object has to be big enough

I see difficulties in concluding what can be considered a planet and what just a big asteroid

hmmm - I think that here we just need to establish a standart of the minimal diameter a planet can have and forget about it. Isn't it just a name...? It's no difference for a star system if we label an object orbiting around it an asteroid or a planet.

 

The funny thing is, some asteroids have moons. Not very big but an orbiting body, none the less.

I think what got the IAU going is that if they allow this renaming of the planet of Pluto, then the next thing you know someone is wanting to go back and recatalogue the stars. Lord knows, there are enough star catalogues already. With enough different names for the same objects that it can become confusing at first glance if you go by the name alone.

 

hmm....what is a planet
plan·et ( P ) Pronunciation Key (plnt)
n.
A nonluminous celestial body larger than an asteroid or comet, illuminated by light from a star, such as the sun, around which it revolves. In the solar system there are nine known planets: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto.
One of the seven celestial bodies, Mercury, Venus, the moon, the sun, Mars, Jupiter, and Saturn, visible to the naked eye and thought by ancient astronomers to revolve in the heavens about a fixed Earth and among fixed stars.
One of the seven revolving astrological celestial bodies that in conjunction with the stars are believed to influence human affairs and personalities.

welll, I'd like to think of it as a planet. It has a consistent orbit, has been in that orbit for quite sometime (though probably alot less longer than many planets in this solar system) and will probably stay that way. But since it hasnt been a permanent resident, lets just classify it as a rogue planet, or polymer planet and basically leave it at that.

 

here is a question for u

i have herd it said that pluto used to be something elses moon

so if OUR moon shot off into space would it be a planet?

 

but where is the border where an asteroid becomes a planet?

 

It wouldn't have a stable orbit around our sun probably then.
We could name it a rogue moon

then thats what pluto is

pluto is a rogue moon

lol, I wouldn't be so fast on that.

btw, are we able to calculate the trajectory Pluto originally came from?
this is quite a stupid question, but hey - shit and miracles happen

i just realised something

the answer to BOTH of the options could be yes seing as the planets r ALL satalites
