SCIENCE GUY EXPLAINS HOW IT'S POSSIBLE AN UNDISCOVERED BROWN DWARF STAR CAN EXIST In OUR SOLAR SYSTEM
Brown Dwarfs are extremely common in our galaxy, the two officially closest ones to us are only 19 light years away. However, their existence was only confirmed VERY recently.


"For many years, efforts to discover brown dwarfs were frustrating and searches to find them seemed fruitless. In 1988, however, University of California, Los Angeles professors Eric Becklin and Ben Zuckerman identified a faint companion to GD 165 in an infrared search of white dwarfs."
[link to en.wikipedia.org]


This is because Brown Dwarfs are only visible in the infrared spectrum:


Where can I purchase an infrared telescope for backyard use?
You can't. Most infrared light from celestial sources is absorbed by the Earth's atmosphere. Only a narrow window of near-infrared radiation (at wavelengths less than about 4 microns) reaches the Earth. Observations at these wavelengths requires that the infrared camera be cooled to hundreds of degrees below zero using a cryogen (such as liquid helium) and requires special solid-state infrared detectors (costing tens of thousands of dollars). Hence, it is impractical to consider a true infrared telescope for personal use.
[link to coolcosmos.ipac.caltech.edu]


More information about Brown Dwarfs:




So if Nibiru existed and was a Brown Dwarf, it would be extremely difficult for anything earth-based to detect it.

So, what about infrared telescopes in space?

Well, there were only 3 such telescopes ever built:


Which infrared observatories are currently operating in space?
There presently is no space-borne observatory capable of observing thermal infrared light from celestial objects. The Hubble Space Telescope (HST) carries an infrared instrument called NICMOS that can observe in certain near-infrared wavelengths, but not at mid-infrared or far-infrared wavelengths. The first space-borne infrared telescope was the Infrared Astronomical Satellite (IRAS), a collaborative effort of the US, UK, and the Netherlands. IRAS orbited the Earth for 10 months in 1983, and the mission ended when its onboard cryogen (refrigerant) was exhausted.
A second-generation astronomical observatory, with much greater capabilities, was the Infrared Space Observatory (ISO). This European Space Agency satellite orbited the Earth from late 1995 through early 1998.
The latest major infrared observatory launched into space will is the Spitzer Space Telescope, a NASA mission which was launched in August 2003. SIRTF was launched into an Earth-trailing solar orbit, and will operate for 5 years or more.
[link to coolcosmos.ipac.caltech.edu]



So if Nibiru existed, those missions would have seen it like a second sun in the night sky. Only a complete cover-up of the images could hide something so colossal...


Now that you know all this, watch this video:

What are Wikisky, Google sky and WWT hiding?

Any large object close to the neighborhood of the sun could be located by reflected sunlight.

Many if not most of the brown dwarfs would appear magenta in color, some orange, others red.

A remarkable property of brown dwarfs is that they are all roughly the same radius as Jupiter. Yes they have greater masses (6090 Jupiter masses), but their diameter would be about the size of Jupiter.

Why? Lack of fusion to offset the gravitational and electric forces that hold matter together. For brown dwarfs the volume of a brown dwarf is governed primarily by electron-degeneracy pressure.

Coulomb pressure is another factor which means that the radii of brown dwarfs vary by only 1015% over the range of possible masses. This can make distinguishing them from planets difficult.

While they are not under going fusion (as in what causes the sun to be so bright and hot), they are undergoing gravitational and electronic compression of matter which is leading to them producing higher amounts of various radiation across the spectrum, including infrared (heat) and x-rays and most importantly radio emissions.

What this means to any 'lurking' brown star in our system, it would leave a decided gravitational wake, which would perturb the orbits of planets around the whole system in a manner that would pretty much pinpoint the location of a massive body.

Secondly, they are not black bodies, they do radiate and reflect electromagnet energies across a wide spectrum including light. Yes it is possible to have missed a large body with optics even today in the outer solar system, however the mapping of the whole of space with radio telescopes has been done and continually gets updated all the time.

A near brown dwarf would have signaled its presence via radio waves. And yes there are amateur radio astronomers out there.

Yes over long distances their radio power is too low to pick up more than the faintest of signals. However anything within the solar system is close enough to be detected.

We can still pickup the signals of Voyager craft and their transmissions are infinitesimally small compared to what a modest small brown dwarf can produce.

You're forgetting the 3600 orbit. It could be 1800 years away from us which is well beyond Pluto's orbit.

Also the theory that brown dwarfs emit radio waves is bsflag

We have a lot of official brown dwarfs near our solar system and none of them were found by radio which has been around a lot longer than 1988.

 Quoting: Anonymous Coward 46411671

Let's do some math about the 3,600 year orbit.

There is a simple formula that gives us the semi major axis when we know the orbital periode:

p^2 = a^3 with p = orbital periode in years and a = semi major axis in AU

a = (p^2)^1/3 = (3600^2)^1/3 = 12,960,000^1/3 = 234.9
Thus the semi major axis of Nibiru is 234.9 AU.

Since we know that it comes close to Earth at it's perihelion, we know the aphelion distance: 2 * 234.9 - 1 = 468,8 AU.

Sedna, a dwarf planet the size of about 1,000 km, was discovered when it was at a distance of 100 AU.
Now imagine a brown dwarf star 280 times the size of Sedna (280,000 km) at, in the worst case (furthest distance from the sun), only 4.5 times the distance away.

Easy to spot only by reflected sun light - even for amateur astronomers.



How many light years are 468,8 AU? - 0.0000158 light years.

OK, the brown dwarf in the picture below, imaged by Dr. Astro in the infrared spectrum, is 12 light years away.

not true! we would be able to detect the gravity changes, by things happening like the sun is in the wrong place, or the moon is in the wrong place.

well have you EVER seen a thread where somebody said the sun or moon is in the wrong place? no? then nubiri can't be real sorry

if it's up to 1800 years away, how would it effect anything? also we've only had the tech to measure those things for only like what, 50 years maybe?

What can "they" hide, if amateur astronomers like Dr. Astro can image a brown dwarf star (Teegarden's star) 12 ly away? [link to www.godlikeproductions.com]

Oh, and btw: Amateur astronomers can easily image Pluto because it reflects sun light.
At what distance do you think amateur astronomers can image an object bigger than Jupiter that reflects sun light, too, when it enters our solar system.

Who is the idiot now?

Re: SCIENCE GUY EXPLAINS HOW IT'S POSSIBLE AN UNDISCOVERED BROWN DWARF STAR CAN EXIST In OUR SOLAR SYSTEM
What this means to any 'lurking' brown star in our system, it would leave a decided gravitational wake, which would perturb the orbits of planets around the whole system in a manner that would pretty much pinpoint the location of a massive body.

Secondly, they are not black bodies, they do radiate and reflect electromagnet energies across a wide spectrum including light. Yes it is possible to have missed a large body with optics even today in the outer solar system, however the mapping of the whole of space with radio telescopes has been done and continually gets updated all the time.

A near brown dwarf would have signaled its presence via radio waves. And yes there are amateur radio astronomers out there.

Yes over long distances their radio power is too low to pick up more than the faintest of signals. However anything within the solar system is close enough to be detected.

We can still pickup the signals of Voyager craft and their transmissions are infinitesimally small compared to what a modest small brown dwarf can produce.

You're forgetting the 3600 orbit. It could be 1800 years away from us which is well beyond Pluto's orbit.
 Quoting: Anonymous Coward 46411671

Let's do some math about the 3,600 year orbit.

There is a simple formula that gives us the semi major axis when we know the orbital periode:

p^2 = a^3 with p = orbital periode in years and a = semi major axis in AU

a = (p^2)^1/3 = (3600^2)^1/3 = 12,960,000^1/3 = 234.9
Thus the semi major axis of Nibiru is 234.9 AU.

Since we know that it comes close to Earth at it's perihelion, we know the aphelion distance: 2 * 234.9 - 1 = 468,8 AU.

Sedna, a dwarf planet the size of about 1,000 km, was discovered when it was at a distance of 100 AU.
Now imagine a brown dwarf star 280 times the size of Sedna (280,000 km) at, in the worst case (furthest distance from the sun), only 4.5 times the distance away.

Easy to spot only by reflected sun light - even for amateur astronomers.



How many light years are 468,8 AU? - 0.0000158 light years.

OK, the brown dwarf in the picture below, imaged by Dr. Astro in the infrared spectrum, is 12 light years away.

Well what if the local brown dwarf was a black body? Yanno, eatting light?
 Quoting: Anonymous Coward 23244749

Do you even know what a Black body is? [link to en.wikipedia.org]
Black body at what temperature? 200 K or 500 K? 1000 K? 2000 K?

You are the usual GLP illiterate who picks up some terms from other posts that sound good and parrots it, without even knowing the meaning of the terms and without looking up the meaning or of it applies to the current situation.

We are talking about a Brown dwarf star. Even if you idealize a Brown dwarf star as a Black body, you would get a Black body in the temperature range of 1000 K to 2000 K, emitting a lot of IR radiation and in the red sectrum. And of course a Brown dwarf star reflects light - per definition it's a failed star, composed mainly from Hydrogen.


Notice how there is no response to the black body question...
