Nemesis', is the ominous name scientists came up with when they began speculating about the sinister space body in 1984. They couldn't have picked a better name: if Nemesis really exists, it should be one of the worst enemies of life on earth. Our solar system is what Nemesis calls `home'. And the bad part is: home is where Nemesis is heading.
What Nemesis is? It's nothing less than our Sun's twin brother. Yes, that's right: a second Sun! In the cosmos, many stars come in pairs. And according to the Nemesis theory, our `star' -- the Sun -- is no exception.
But wait -- why then do we see only one Sun? Well, for one thing, Nemesis is REALLY far away at the moment. Nemesis orbits the Sun in a huge ellipse, with its furthest point a distance of three light years away. But once every 25 to 30 million years, Nemesis closes in on the Sun. It slams into the outer regions of our solar system: a place called the Oort Cloud, at a distance of half a light year away from the Sun.is this reaL????

No it doesn't exist, if it did we would have detected the wobble in our sun's orbit by now. A mass a large as the sun itself would throw the center of rotation for the solar system far outside what it is now. All of the known mass of the planets, moons and other bodies of the solar system is a small fraction of the sun's mass, therefor the center of rotation for the entire system is very near the center of the sun. A huge mass gravitationally tied to the sun would make this system center of rotation fall far outside the sun, and depending on distance would actually fall outside the orbit of the inner planets. This would cause our apparent progress around the galaxy to perform a looping act that would be quite apparent to observers.

It is a hypothesis. But not a very good one. At a distance of only 3 light years, any star would be easy to see. A star as bright as the sun only 3 light years away would be one of the brightest stars in the Sky. Even a red dwarf would be bright enough to see with pretty small telescopes and would have already been cataloged. In other words, there is no such star.

There is no scientific basis for Nemesis. The closest star to our solar system is Alpha Centauri, which 4.7 light years away.
Scientist have done a pretty thorough job of cataloging all nearby stars, including brown dwarfs which are exceptionally difficlut to detect and have found no stars that orbit with our own, nor any closer than Alpha Centauri.

This is very speculative, primarily because there is no evidence for it at all.
Think about what evidence you would look for...
Perhaps periodic extinctions in the fossil record - that appear at regular intervals...
Unfortunately for the Nemesis hypothesis, this is not observed. Extinctions are episodic, not periodic.
And given the devastation to life that this hypothesis purports, this lack of evidence not only does not support the hypothesis, it goes a long way toward disproving it.
It would make a good Hollywood feature, though.

So far there's no observational evidence that Nemesis exists. However, just for the helluvit, you might want to read over this website which presents some interesting ideas and facts ==>http://www.slowmotiondoomsday.com/deathstar.html

I hope you plan to Track that Star: Nemesis. Wait a minute. They've already made that movie.

No, that will not be possible because He conquered death when He died the first time so He can not die again. additionally, when He comes to get the Church He will not come on to the earth and so you can not get your hands on Him Lastly, when He comes to deliver judgment, He will be within your reach but then you will for the first time understand whom He really is. By then it will not even cross your mind to consider killing Him because you will realize that all things were really created by Him and that all forces of hell combined plus you and all the rebellious people can not even as much as lay a finder on Him

Conspiracy theory (that is... BS).
Show me the evidence. Show me the doppler shift of a brown dwarf that is coming towards us, and show me it's distance measured via parallax.

No, that's just a crackpot theory. I think we would notice another flippin' star if it was that close.

No, it is not real. It is one of the stupidest things I have ever heard.
