Sitchin's work doesn't rely on a brown-dwarf. Zecharia Sitchin posits the rogue-planet theory.

No, he does not.  Rogue planet does not mean a planet with a 3600 year orbit, it means a planet which does not orbit any star.  It has nothing to do with the "Nibiru" claims, and I don't care who it comes from.

is there a way to tell between a roge planet and a 3600 year orbit planet that hasnt been discovered yet? if you find this theorical planet today, how long will take you to tell between one and the other type of.

Depends on how far away it is when it's discovered.  The closer, the faster.  If it were going to be here this year as part of some kind of "doom" it would already have to be deep inside the inner solar system.  An approximate orbit determination that would tell us the difference between a hyperbolic and a ~3600 year orbit would not take long at all.  The orbit determination I've been doing on SDO for the last several days is actually much more difficult because I'm trying to make it very, very exact.

and if this planet really come too close and kill almost everything and erease all your data, how could the people 3600  in the future tell that it is a periodic panet and not a roge one..??

Same way, basic orbital determination through astrometric measurement.

Original Message Free-floating “rogue” planets may occasionally dip into the inner Solar System, according to new research by the University of Buckingham Centre for Astrobiology in the UK.
