A new planet?

I'd like to hear some opinions on this. Could it be a new planet? Is pluto really a planet? What's going on in the universe!?!?

If Pluto was dragged into our solar system from somewhere else then it's not a planet. If it was formed from the ejected materials of our own sun then it is.

That said, when does an asteroid become a planet ?

As for the new orbiting body, I feel there's not enough data to answer the question.

One of the things I hate about science is that you can grow up your entire life believing you know the truth and all the facts, only to find out that your perceptions were wrong simply because the facts were based on what we knew at the time.

Says who?

plan·et
Pronunciation: 'pla-n&t
Function: noun
Etymology: Middle English planete, from Old French, from Late Latin planeta, modification of Greek planEt-, planEs, literally, wanderer, from planasthai to wander


Doesn't say anything about where it wandered in from!

My dictionary doesn't say anything about where it comes from either. I was referring to planets that belong to a solar system, which is what I believed the gist of the original post was about.

perhaps it is the planet nebiru that the sumarians and babalonians wrote about in ancient times.. The mysterious 10th planet .. home to the annunuki - the gods of heaven and earth

Naah, it's probably just a rock

No way man! That's one of the COOLEST things about science. Every time we turn over a rock and find an answer, we look over our shoulders and find a bunch more rocks to turn over. I think that in the past they (i.e. the science community in general) has tried to say "OK, now we know everything" but more and more we're beginning to understand that we'll never understand it all, there will always be one more layer to the onion. Scientists cast their sight outward to the farthest reaches of the universe, and inward to the smallest subatomic particles, and no end is in sight. It's a blast!

This: http://www.gsfc.nasa.gov/topstory/2004/0220stardisk.html Click/Save-As on the mpeg file. Neutron star explosion in real time. Kewl!! "pouring out more energy in three hours than the Sun does in 100 years..."

So I try and I scream and I beg and I sigh
Just to prove I'm alive, and it's alright
'Cause tonight there's a way I'll make light of my treacherous life
Make light!

I thought that they only discovered the eighth and ninth planets when Galileo was around? Which is why Nostradamus made his predictions based on only 7 planets (probably why so many are wrong!)

So how could the Sumerians have been looking for a tenth planet if they only knew about 7?

Not that I REALLY care but I am very bored...!

Much later than Galileo...

Actually when we turn over a new rock we only find another THEORY. science has no answers. all of them are guesses that seem to make the most sense at the time

but it does let the imagination go wild!

I remain a skeptic but there is documented proof that the sumerians depicted 12 celestial bodies on many cyllander seals. 10 planets our moon and the sun. It was also a foundation of their belief structure in their story of creation the " enuma elish" where a celestial invader (the 10 th planet) crashes into our solar system creating earth and continuing on its own 3600 yr orbit in our own solar system.

Remember this is not modern science so even if they had correct knowledge, it doesn't count because we may have not been able to prove it until recently

So how long have we got before,
1. America decides to send a probe there
2. Invade it if they find it has oil
3. It becomes too polluted

When, and if, it begins orbiting the sun.
The most common definition of a planet I have read state that it must not generate light of its own and must orbit the sun (or any star.)
This definiton does not appear to exclude comets on an elliptical orbit though.

Is pluto really a planet?

Yes it is.
There are widely acknowledged to be 2 types of planets, solid terrestrial and Jovian (giant gaseous) planets. A suggested structure for Pluto is a small rocky core covered by an extensive water ice mantle with a crust of methane ice.
And so, Pluto is argued by some astronomers as not being either a true terrestrial planet or a true Jovian planet because it has characteristics of both.

During the late 19 century; astrologists, priests and early astronomers around the world proposed theories of additional planets; including Vulcan (between Mercury and the Sun), Lilith, Nibiru and PlanetX out beyond Neptune. PlanetX was later confirmed as Pluto but no modern scientific evidence exists to support the existence of the others.... until the article that started this thread appeared.

?? Uh, Earth isn't formed from "ejected materials from our sun." Our best analysis of how the planets came into being is condensation out of a gas/dust cloud. The sun condensed in the center, the planets condensed further out. Once the sun ignited the solar wind blew the lighter elements out of the inner planetary rings, which is why the inner planets tend to be rocky and the outer ones are mostly gas giants. The area beyond Pluto (the oort cloud) is partly composed of that early material and partly composed of interstellar wandering dust and gas.
