Even if a companion star had significantly less mass than the Sun the orbits of the planets would be radically different. It would throw off the barycentre (center of mass)of the solar system. Most people assume that the Sun is the barycentre for our solar system, but this isn't true. Due to the mass of Jupiter the barycentre is outside the Sun. So, if there were an object several magnitudes more massive than Jupiter in the solar system it would throw off the barycentre even more. However, we know this is not true because our models for objects such as long-period comets, that use the barycentre, are accurate.

Thanks for that Xcalibur, i didn't know that.
Having thought about it though, and i'm not disputing what you say, but wouldn't a barycentre outside of the sun, cause a wobble in the sun (for want of a better term)?

IRC +10216 or CW Leonis is a well-studied carbon star that is embedded in a thick dust envelope. It was first discovered in 1969 by a group of astronomers led by Eric Becklin, based upon infrared observations made with the 62 inches (1.6 m) Caltech Infrared Telescope at Mount Wilson Observatory. Its energy is emitted mostly at infrared wavelengths. At a wavelength of 5 μm, it was found to have the highest flux of any object outside the Solar System.
yeah, i don't really trust all Wikipedia sources...that's an easy out for a lot of peeps on here. look how many times that CW Leonis page has been modified since 2006.

All I'm say'in is I heard that on CNN myself. That a brown dwarf star is in our solar system. Dosn't mean I believe it. Mainstream could actually make it less believable.
Now my most pertainent question. What the hell is that lil devil all about?edit on 25-8-2011 by randyvs because: (no reason given)
This would be news to me, could you please post a link to a video or news source from CNN saying this?
I read the articles a while back but I always take what the MSM says with a grain of salt.

I know, I know... it's so very very hard to click the references in a Wiki page. Much easier to just hand-wave and say, "It's Wikipedia, therefore... conspiracy!"

Always a good idea but there is nothing in either of those articles which says anything about a brown dwarf being found in the Solar System.
I live in Marquette, Michigan. Today 9/14/12 I was riding my bicycle around Presque Isle park and decided to stop and take some pictures of the sun. It was about 7:20 pm or so. These are the pictures that I took:
