I don't know where to start concerning the rubbish posted in the article that was originally referred to. If you just google G1.9, you will find lots of references, and also pictures. It is clear that this is not a planet. Here are some of the things a real scientist, Mike Brown, (not some anonymous unspecified set of "Spanish Astronomers", or someone writing a bogus article about such), who has actually discovered planetoids in the outer Solar System has to say on his blog
http://www.mikebrownsplanets.com/200...nd-of-fall.htm:
"There is *definitely* not anything 1.9 Jupiter masses out at 100 AU or we would have know a century ago!"
And regarding the article at viewzone.com/browndwarf.html:
"Wow; that web site does an amazing job of taking real science and making it crazy. The discovery is a *supernova remnant* not a planet. And it is nowhere near us (though it is moderately close to being in the same *direction* as Pluto). The actual scientific press release is here:
