Ive read in the New Scientist that this may be true but what evidence is there to prove that there is another star that orbits our own.

Actually, as mad as it sounds, it's quite possible. The majority of solar systems have 2 suns, ours is a bit unusual in having only one.
The reality is that we don't know for sure what we have in our solar system, we could have hundreds more planets that are currently too distant for us to detect. And we could also have another sun.

I've heard about this one too. The link gives the evidence suggesting the existence of such a companion star, because of the pecularities of the orbit of Sedna. Many binary star systems involve a small dwarf star that can be very dim and difficult to see, and binary star systems are more common than solitary stars. But some of the other folks have the right objection, if there was such a companion star, the wobble of our own sun would be noticeable, so it'd have to be a really SMALL dwarf star. Remember, Jupiter was almost such a star.

The idea that the sun has a companion goes back to at least 1977, when it was suggested that some observations of pulsars could be expained by the sun "wobbling". In 1984, the idea of a companion star called Nemesis was put forward to explain periodic mass extinctions. Neither of them is exactly mainstream though!
Just as an aside, Jupiter's about 80 times too small to be a star.

Andy Lloyd's theory regarding a brown dwarf as Nemesis, Nibiru, the Egyptian Phoenix and the Messianic Star. The Sun has an binary Dark Star. andy lloyd is trying to prove that there is a fail star or brown dwarf (larger than jupiter) orbiting just outside our solar system. it seem that the cometry clould orbiting our solar system which give us our comets is not random but is affected by the this star passing near it. very interesting if true.

I think you might be confused with Jupiter, which with another 10% added to the gas giant would have had the possibllity to become a small star which would have been a obiting companion to our sun.
This is the only thought that comes to mind as a star has a lower limit size that is needed to cause nuclearsynsthsis, and anything near this size would be noticable to us.
I hope this helps.

I doubt it. The sun is so close that we'd see some very obvious effects of this, like the sun wobbling and extra gravitational effects on the other planets, including the Earth. We can see the wobble of other stars due to the existence of larger planets orbiting it from light years away, so on our star it would be very visable!

Seems pretty unlikely, if they can infer a planets existences from a it's gravitational effects on a distant star, and have the Hubble telescope to use,, I would think it would have been found by now. just my opinion though

No, not really. I mean, how come wherever you got this idea from know that and nobody knows about it? I mean we would also learn about that in school, if it was there, wouldn't we? Does not make sense.

Yes, Its name is Jupiter, and it's a radio star.

If there were, it would have to cause our sun to wobble.
