"Sedna, or 2003 VB12, as it was originally designated, is the most distant object yet found orbiting our Sun. It is three times further away than Pluto (average distance to the Sun is 5.9 billion km or 3.6 billion miles). "

It's apparently about the same size as Pluto and may even have a moon of it's own. Neat.

For the fear of repetition, I will refraim from any Uranus jokes.

 

[danielson]

apparently there;s a whole bunch of other debris out there in a similar orbit...the explanation for the gas giants being so far out has always been they are made up of less dense elements, so the fact pluto and this one are rocky (as far as i know) perplexes me, as well as there being all that debris

and also....why havent we seen this sooner....? we sent the hubble up quite a while ago! this was a completely different orbital IR scope if i remember the news report right

 

[Code]

The great majority of Hubble's time in orbit has been spent with a faulty parabolic mirror. So they had to operate within the parameters of that mirror, which didn't allow for far space viewing.

It got repaired 3-4 years ago.


Plus, the galaxy is big fucking place.

The debris orbiting beyond Pluto is called the Kuiper Belt. This Sedna is by far the largest object yet discovered in the belt. Many astronomers believe the Kuiper Belt may be the same type of debris that orbits in the asteroid belt between Mars and Jupiter, holding with the exploded planet theory (the KB rocks may be debris that was blown away from the planet's orbit but without sufficient force to completely escape the sun's gravity).

The following statement should answer all the "why didn't we find it before" questions :

the galaxy is big fucking place.

 

[hamstershaver]

they were gonna call one of my ex gfs ass the 10th planet but it was turned down by a 5-4 nasa vote, close call

 

[BO-DEN]

anyone want to know something more intresting in the PLANET X
look up NIBIRU

 

[strongsmartsexy]

Plus, the galaxy is big fucking place.

Especially considering that what they're showing in pictures is stuff that occured approximately 14 Billion years ago.

 

[The Wenis]

this is old news. alf told us all about the 10th planet back in the 80s.

I have enough of a rough time believing there is intelligent life on this planet. So, it is my sincerest hope that there is on some other planet and that they have enough compassion to come here and show us how it's done.

In our galaxy? Maybe.
The known universe, most assuredly.

The earth, it's whole history of life and it's future demise is nothing but a short breath in the life of this galaxy... makes our lives feel somewhat insignificant…. doesn't it?

i know, but you;d think they could spot a whole bunch of floating debris in orbit

The debris orbiting beyond Pluto is called the Kuiper Belt. This Sedna is by far the largest object yet discovered in the belt. Many astronomers believe the Kuiper Belt may be the same type of debris that orbits in the asteroid belt between Mars and Jupiter, holding with the exploded planet theory (the KB rocks may be debris that was blown away from the planet's orbit but without sufficient force to completely escape the sun's gravity.

hmm, i was thinkings along similar lines...i wonder how many rocks are really out in that belt...it would be interesting to know its total mass

It was either Scientific American or Discover that I read the total mass of the galaxy is about half of what scientists originally thought.

its not that far out for me... everything on nibiru and stizchen is based on the oldest writtings that exsist.

sumer had tablets discribing the size and colors of planets in our solar sytem thousands of years before our civilization discovered the world was round.

Last night 60 Minutes had a story on the Hubbel and what it's done to science. They've discovered that the universe is actually expanding at a faster rate. Which REALLY screws up gravitational theory.

yeah i remember reading about that in the paper...the science excuse they came up with was that the universe has lots of dark matter in it, which is currently undetectable


the thing that weirded me out the most was the fact that the voyager probe is now slowing down....and they dont know why

 

[Forge]

It's not just voyager, but both Pioneer 10 and 11 are also slowing down. The measured force is working directly against the probe's path of motion, almost like the sun's gravity is stronger than it is. One theory is that dark matter in our system has slowed it down, but that is not widely accepted because if there was that much dark matter then we would see it's effect on the planet's orbits also. Another theory is that photons (light particles) are transfering enough momentum energy to work against the craft's motion.

The truth is, we don't have any concrete idea why they are slowing.

Are they slowing down or are they at the point to where other things are speeding up?

 

[Forge]

No they are slowing down. They distance they have actually traveled is less than the math predicted they should have traveled by now. In other words, some miniscule force is acting against them. If this mystery force remains constant then they will eventually slow to a complete stop (a very long time from now).

I'm not deliberately being trite. However, if the universe is expanding at a faster rate, that changes the notion of gravity and it's possible that the mathematical calculations they have are inaccurate. Not that the explaination you have is any better or worse, I just thought you might be able to shed more light on it.

Actually, the fact that they are slowing down proves that our current math is innacurate in some way and does not account for everything in space travel. The question now becomes: what part are we missing...?

A probe sent from Earth to Mars would not be affected in any measurable way by this mystery "force", but a probe sent from Earth to this new planet Sedna would need to take this into account.

Perhaps whatever bridge we are missing between stellar and quantum physics will explain this new force, someday.

"Sedna, or 2003 VB12, as it was originally designated, is the most distant object yet found orbiting our Sun. It is three times further away than Pluto (average distance to the Sun is 5.9 billion km or 3.6 billion miles). "

It's apparently about the same size as Pluto and may even have a moon of it's own. Neat.

I have misgivings about it being a planet. Most astronomers believe Pluto came from the Kuiper Belt. Right outside our Solar system. Pluto's average density is about 2000Kg/metres cubed, while terrestrial planets have much higher core densities 3300-5500 Kg/metres cubed, while jovian planets have low densities due to their rich hydrogen-helium composition.

And if its 3 times away from Pluto and IS orbiting, the sun. Using Keplers 3rd law that the square of the orbital( Period of the orbit around the sun in days cubed)(around the sun and in Earth Years) s proportional to the cube of its semi-major axis(In astronomical Units). Almost all the planets have elliptical orbits.

Ok, since the radius is 5.9 billion kilometres, and its orbital period is unknown, you can use ratios to calculate its orbital period as pluto's are known.

With its orbital eccentricity(flatness of ellipse) arround 0.750, semi-major -axis * 0.750 = average distance from the sun.

Therefore, semi-major-axis = 5.9/0.75 = 8.825 Billion Km

So, semi-major axis(cubed) = (6.87 * 10 (exp) 25 Km)
In astronomical units( 1 AU = 1.5 * 10 (exp) 8 Km = 4.58 * 10 (exp) 17 AU's


Therefore(Orbital period) = 676756972.6 Earth years

Takes that long for that Pseudo-planet to go once around the sun. More than 6 Billion years.

Gravitational theory?????

LOL.....I think you mean the big bang theory...and no. It actually proves some of its assumotions. The recession speed of the universe is increasing because the planets are moving farther and farther apart...therefore less gravitational pull is exerted on them by other stellar matter. Like other planets and stars. And since there is no friction in space.....the planets speed up.

From the recession speed of the universe, you can calculate the Hubble constant, and taking the inverse of it you can find the age of the universe: 15 Billion years.(1/H)

Maybe because electrons have momentum, and according to QCD can affect the direction and speed of an object. Space has a lot of ions floating around,and thos ions(With electrons) can hit any mass they are atracted to, and divert it from its course or slow it down. There also inter-stellar dust that collects on the craft, increasing the mass of the craft, and therefore the speed.

No, I meant gravitational theory. What you laid out as "simple" seems to have some scientists "baffled" and are trying to find other theories for it.

Here is a nice picture showing the orbit of Sedna:

http://images.spaceref.com/news/2004/ssc2004-05d_medium.jpg

It's actually not a true Kupier belt object, but they aren't sure what else to classify it as because it is way too close to be an ort cloud object. Very cool orbit, though I doubt it's actually a true planet after looking at that pic. If it is, something traumatic must have happened to throw it out of whack like that.

yeah. that's way to eliptical for mainstream astronomers to accept it as a planet. they already argue pluto isn't a true planet due to its size and orbit. this rock is smaller and has an orbit more like some of the comets.

They estimate that it takes 10,500 Earth years for Sedna to make one full revolution around the sun.

fuck...that is almost how long man has been on the planet....i was just remarking to someone if it was roughly that long

FREAKY!! i wonder what this does to atrology as well


now.....who can tell me what the Oort cloud is....just gas like hydrogen/helium? or is it invisible charged particles?

 

[Forge]

now.....who can tell me what the Oort cloud is....just gas like hydrogen/helium? or is it invisible charged particles?

The Ort cloud is still theoretical and has never been proven to actually exist. Here is a description of it:

"In 1950, Jan Hendrik Oort (1900-1992) inferred the existence of the Oort Cloud from the physical evidence of long-period comets entering the planetary system. These comets are observed to come into the Solar System from all directions, which implies an immense spherical cloud of trillions of small icy, planetary objects -- all potentially active but currently dormant comets -- that extend as much as two light-years outward from Sol. In contrast, the Edgeworth-Kuiper Belt is roughly 100 times closer to Earth than this hypothesized Oort Cloud. Estimates of the total mass of this Oort Cloud range from about 40 times that of Earth to greater than that of Jupiter.

Oddly enough, Oort Cloud objects were probably formed in a region of the protoplanetary disk that was located closer to the Sun than the Edgeworth-Kuiper Belt objects that persist in the orbital plane of the planets (ecliptic) to this day. During the first 100 million years of the System's birth, small planetary bodies that formed near the developing giant planets would have been ejected from their neighorhood through gravitational encounters (Levison et al, 1999; and Dones et al, 1998). Those that did not escape completely from our Sun's gravitational pull eventually became part of the distant Oort Cloud, which became a vast repository of icy bodies tossed out of the early Solar System."

Here is a picture of what the Ort cloud would look like:

http://www.solstation.com/solsys/oort.jpg


This is only one theory on where comets and asteroids come from, but it is the most widely accepted theory. The next popular theory (and the one I believe in) is that comets and asteroids originate from a planet that exploded between Mars and Jupiter. The asteroid belt is matter that was expelled along the planet's solar orbit, and comets and asteroids with a large elliptic orbit are matter that was expelled in every other direction but couldn't escape the sun's gravity. In this scenario, the Ort cloud would not need to exist.

 

[Code]

It's also just a plantetoid at this stage.
They convinced they will find many planets much much larger in size.


The definition of a planet is something like: an object in orbit around the Sun that is considerably larger than objects nearby.

 

[Fonz]

They estimate that it takes 10,500 Earth years for Sedna to make one full revolution around the sun.

There goes Kepler's 3rd Law. The eccentricity of that orbit must be near 1.
