user posted image rThe Binary Research Institute (BRI) has found that orbital characteristics of the recently discovered planetoid, "Sedna", demonstrate the possibility that our sun might be part of a binary star system. A binary star system consists of two stars gravitationally bound orbiting a common center of mass. Once thought to be highly unusual, such systems are now considered to be common in the Milky Way galaxy. Walter Cruttenden at BRI, Professor Richard Muller at UC Berkeley, Dr. Daniel Whitmire of the University of Louisiana, amongst several others, have long speculated on the possibility that our sun might have an as yet undiscovered companion. Most of the evidence has been statistical rather than physical. The recent discovery of Sedna, a small planet like object first detected by Cal Tech astronomer Dr. Michael Brown, provides what could be indirect physical evidence of a solar companion.

Matching the recent findings by Dr. Brown, showing that Sedna moves in a highly unusual elliptical orbit, Cruttenden has determined that Sedna moves in resonance with previously published orbital data for a hypothetical companion star.In the May 2006 issue of Discover, Dr. Brown stated: "Sedna shouldn't be there. There's no way to put Sedna where it is. It never comes close enough to be affected by the sun, but it never goes far enough away from the sun to be affected by other stars... Sedna is stuck, frozen in place; there's no way to move it, basically there's no way to put it there – unless it formed there. But it's in a very elliptical orbit like that. It simply can't be there. There's no possible way - except it is. So how, then?"

No. Just no. We'ed know by now. Not gonna buy it.

the suns twin would be a dead star, therefore sheading no light and just supplying a strong gravity. personally, it could make sense that we do have a twin. what else could distaught sedna's orbit.

Dead star or not, we stll would have fond it before now.

How can you be so sure? We don't know everything. We only found an object bigger than Pluto last year.

Even a dead star would give off some radiation.

Personally I'm extremely dubious that such a companion exists as it would be visible to infra-red telescopes. However it is not impossible. The Binary Research Institute theorises that if the object lay in the direction of galactic centre then the back ground radiation could “camouflage” a black-hole or a bown dwarf.

oh I know it'd give off radiation, just no visable light.

hmm, what if we passed another solar system in the long ago past, couldn't that have distorted sedna?

its known galaxy's can 'bump' into each other (though then the engulf each other), and solar systems are continously moving away from the centre of the galaxy, so if we dont have a dead twin star...

just a thought.

Most astronomers think that passing stars disturb the Oort cloud and cause comets to fall in towards the sun. Sedna though is a Kuiper Belt object which is much closer to the sun than the Oort cloud.

The BRI claim that Sedna's orbit could only remain stable with the help of this companion. I don't know enough about orbital mechanics to know whether they are right or not.

This teory could explain the existence of some planets like (Nibiru) that are in the other system,its possible that our sun could have a companion and that they get closed in some time putting together the both system or only get closed to us.
Could be??Its impossible?? I dont think its impossible.
Maybe its time to both system getting close thats why the most far away planets of both system are appearing closed.
Example: in the other system could be there a planet like Earth and the people are talking about Pluto as we are talking about Sedna.

having a binary system doesn't mean there's two solar systems in one. the sun's twin would be dead, just giving off radiation and gravity. the two stars just somewhat orbit one another, one more than the other. there are no planets orbiting the suns (dead) twin, the twin is just tugging at a few objects - sedna for example.

which is what they're trying to find out.

Interesting article.

And interesting points everyone is making.

Does seem strange that we have missed such a vast object hovering in the blackness of space. But then space is a big place, in its vastness almost anything is possible!

I am doubtful of this...A binary star system would be throwing of parallax...

Stalker
Heh, and they post this not two days after my science teacher tells me that life cannot exist in a binary system...

Not if the object is of relatively low mass. A distant brown dwarf would not cause a noticable shift in parallax.

Hmm this reminds me of a star I recently read about called "Nemesis". According to the passage, Nemesis was believed to be the Sun's binary star, the Sun being the stronger of the two. Nemesis is much duller than the Sun; a reddish color, which means weaker in star-language. Evry 100 million years or so as the two orbit around each other, Nemesis would pass through the Oort Cloud, a cloud of comets surrounding the solar system, and send waves of comets towards the inner solar system.
