"Nibiru" often claimed to be a "brown dwarf" or a "failed star". This would put its mass aproximately between 13 and 75 Jupiter masses. However it is often also said that it weighs in at about 4 to 8 Jupiter masses, meaning it is really only a big planet and not a brown dwarf -- as I understand the way Astronomers classify these things.
Irrespective, on the balance, an object of this sort that ordinarily dwells in the far outer solar-system would very likely have a composition and structure similar to Jupiter sized planets ie a mixture of Hydrogen & Helium in gasseous and liquid layers with perhaps a small silicate core.
For an object say, 4-8 Jupiter masses and of similar structure and composition, it would still be approximately the same size as Jupiter (maybe a fraction smaller actually) -- only much denser. Proceeding on these reasonable assumptions (they can only be assumptions because the object actually does not exist at all as I said) it would probably have reasonably similar properties to Jupiter in terms of Albeido (ability to reflect light) and also emit radio and infrared radiation like Jupiter.

you can't expect us learned astronomer folks , some of us with actual degrees even in physics to read your rubbish about this ficticous object with up to 7t jupiter masses on a highly elliptical orbit (period 4000 years) with out laughing.
If you know it's position and it's period and mass , where are the gazetted orbital elements ?
Give them and I'll plug them into Guide V8 and produce a finder chart so we can all have at look at it , even a very cold brown dwarf will reflect some sun light and so it will be easy to spot with the naked eye if it is even 1/8 the size of Jupiter in dimensions if it is even as far off as Saturn's orbit (look up gas reflectivities if you don't believe me). We can easily see Saturn and Jupiter with the naked eye because of the reflectivity of hydrogen and methane. It is clear you know nothing about physics.
We should also be hearing of massive orbital perturbations due to its presence in the inner solar system.
None of this has been provided and observed.
So just a load of UNREALISTIC nonsense.
Enough of my valuable time has been wasted reading this person's nonsense about
Nibiru (the invisible companion to Sol that no one can see ....)
I'm giving this thread the flick.
