I am sure that something that huge coming in our solar system just beyond Jupiter would be seen very easily, with its own shine.

OMG!!!! he ran out of smokes!!!!! thats way worse than Elenin
seriously I don't see why any of this is relevant to our survival - if Elenin is a super mass thats going to slam into our planet, there's nothing we can do to stop it - and if it spews us into a nuclear winter.... well how do you prepare for that seriously? does walmart carry a sun ? perhaps in their lawn and garden department?
A 'brown dwarf' and a gas giant planet (like Jupiter) are made of the same stuff.........
brown dwarf
n
(Astronomy) a type of celestial body midway in mass between a large planet and a small star
brown dwarf
A celestial body with insufficient mass to sustain the nuclear fusion that produces radiant energy in normal stars. It is believed that a brown dwarf is formed with enough mass to start nuclear fusion in its core, but without enough for the fusion to become self-sustaining. Theory suggests that a body with about one percent of the mass of the Sun or ten times the mass of Jupiter can generate this initial fusion, but that it needs at least eight percent of the Sun's mass to sustain the fusion. After the fusion ends, the dwarf still glows for a period from radiating heat, with a surface temperature of about 2,500°K (4,532°F) or less.
gas giant
A large, massive, low-density planet composed primarily of hydrogen, helium, methane, and ammonia in either gaseous or liquid state. Gas giants have swirling atmospheres primarily of hydrogen and helium, with no well-defined planetary surface; they are assumed to have rocky cores. They are also characterized by ring systems, although only Saturn's is readily visible from Earth. Our solar system contains four gas giants: Jupiter, Saturn, Uranus, and Neptune. The majority of extrasolar planets discovered so far are the size of the solar system's gas giants, although they orbit their stars much more closely and may differ in composition from ours. Also called Jovian planet.
Currently there is some debate as to what criterion to use to define the separation between a brown dwarf and a giant planet at very low brown dwarf masses (~13 MJ ), and whether brown dwarfs are required to have experienced fusion at some point in their history.
Distinguishing low-mass brown dwarfs from high-mass planets
A remarkable property of brown dwarfs is that they are all roughly the same radius as Jupiter. At the high end of their mass range (60–90 Jupiter masses), the volume of a brown dwarf is governed primarily by electron degeneracy pressure,[2] as it is in white dwarfs; at the low end of the range (10 Jupiter masses), their volume is governed primarily by Coulomb pressure, as it is in planets. The net result is that the radii of brown dwarfs vary by only 10–15% over the range of possible masses. This can make distinguishing them from planets difficult.

Well, in a nutshell, isn't it obvious what a slew of amateurs would and could do? (We see it used, every day on ATS....).
YouTube.
Nothing to stop any concerned citizen of any nation, IF they saw a true, and dire threat of any size.
Not to say that the amateurs would see everything, of course. But, in this case, we are discussing a couple of well known soon-to-be "NEOs". Sure, there could be a "planet killer" out there, bound to impact...and, sure it could be (as yet) undiscovered by ANYONE.
See? (or not?)
Well,there are those that advocate the planning and preparing for some sort of diasaster....the Mormans for example store 1-2 years supply of food for every member of the household.....in my case we have,on hand,16 months(as of now)for each member of the household....now if we go into a severe long term situation,there isnt any hope...I cant speak for anyone else,but if I have the opportunity to prepare(25-40 a week of my households discretionary income for the last 3 years)and dont,and I have to watch my kids cry with hunger,then I havent done my job as a head of household....since the Government,in Jan of this year,purchased 1billion worth of the freeze dried canned food put out by Mountain House,in addition to the 42 million MRE meals they mantain on hand at any given time,which keeps me from purchasing any for the near future,Im thinking they might know something....there are plenty of arguments for and against storing supplies,I choose to stockpile...you do what you want....it can always be eaten...and if we do die in an inferno,I havent really lost anything...
- and if it spews us into a nuclear winter.... well how do you prepare for that seriously? does walmart carry a sun ? perhaps in their lawn and garden department?
Thank you

I'm going to assume you either have a very large telescope or a CCD camera for a smaller scope, otherwise you're not going to see anything as it's very dim.
These are the geocentric coordinates for Elenin for the next several hours. As I do not know where you live, this is its astronomic position with no atmospheric refraction factored in. All times are GMT.
