Too Soon for Tyche?

[Hoover]

There is all the buzz today about the possible planet Tyche. It has been theorized for years, but a couple of guys from University of Louisiana at Lafayette claim with data from the Wise Satellite Telescope they have strong evidence which they will present later this year. Probably too soon for an addon until they give better info. That is, if they do at all

It would be a little over 1/4 light year from the sun. 4 times Jupiters mass, so not a brown dwarf.

It's an old hypothesis. It'll probably be years before it's detected, if at all. They're just saying that if it exists, it might have been seen by the Wise survey.

The name Tyche is already taken, though, for the asteroid 258 Tyche.

There are different aspects of the story on different media. Of course the geniuses at Fox news and CNN are delivering it as fact and are even showing "pictures" (drawings) of it. On the net it is given as possibility. They (the astronomers) say the data will be released later this year. But as I understand it, it is still indirect evidence.

I didn't think objects as small as comets could be seen as far away as in the Oort cloud. But it is the odd orbits of these which is part of the evidence.

Sorry about hxxp. This is my habit as on some boards they don't like direct links for some reason. However the browser I use, Firefox 3.6, seems to resolve them so there is little point in having them anymore.
