And if it did have a 3600 year orbit and was the mass of a brown Dwarf which is 8-10+ Jupiter Masses or more
Brown Dwarfs vary in size from the the size of Jupiter to 80 Jupiter masses. There is plenty other information here on brown dwarfs, it also supports
the fact that most are only visible in infrared.
You are confusing "size" and "mass".
Brown dwarves are about the SIZE (diameter) of Jupiter, +/-. Their MASS is radically different, however, running from around 13 Jovian masses to 75 or
80. The lines are not well defined, but those are the generally accepted parameters.
This means their DENSITY is a lot greater than Jupiter's.
If a body with 13 Jovian masses (at a MINIMUM) were in the orbit attributed to Elenin, havoc would have been wrought in the solar system long ago, and
we would not be here now.
If a body of that mass were inbound from outside the solar system as an interloper, and were at the position of Elenin now, we would SEE it in the
night sky, brighter than Sirius. It would reflect sunlight at a minimum, and likely radiate light of it's own (unless it were VERY old), even if
mostly in the infrared. Likewise, Jupiter radiates a bit over TWICE the energy it receives from the sun, but it doesn't "glow" like a star in the
visible. Nonetheless, we can see it very clearly in visible light.
Please do read your own links before posting them and misquoting from them.
