here's the sun as viewed thru 4 different cameras this morning:
do you see an additional sun like object or planet X?
Quoting: deltawaveDo you own an infrared telescope? This object is a "brown dwarf"...meaning it's an un-ignited sun that can't be seen in the visible light spectrum.
Where did you hear it 'can't be seen in the visible light spectrum'? They are dim but are actually brighter than Jupiter. From here you find the Brown Dwarf Absolute Magnitude range is from +15 to +20 - [

From here you find that Jupiter has an Absolute Magnitude of +26 - [
link to books.google.com] Now considering that Jupiter is around the 3rd brightest planet in the solar system, any Brown Dwarf approaching the orbit of Jupiter would quickly be recognized as one of the brightest planets in the system and would be seen visually long before that....
Not true and this is why.......
The gravity is strong but the lack of fusion leaves a poor solar wind. This means space dust/debris will cover the star like an egg shell. Right where the weak solar winds keep the debris pushed away but the gravity keeps it pulled in. At this point, because it is very close to the failed star, it creates a dense barrier blocking all visible light.
Our Sun has this 'shell' as well but it is blasted way past Pluto, making it ultra thin and practically translucent.
This is why a Brown Dwarf needs infra-red detection. Because heat can still pass through the shell.
If a brown dwarf came close enough to Earth, we would get bombarded at once by millions of rocks, dust particles, boulders, etc as we pass through the debris shell. Shortly after that we enter the inner region where it is glowing red. Our sun will be hard to see if at all and the sky will turn blood red at day and night. The Moon would be a deep bloody red as well.
The abundant iron dust would quickly turn to red rusty dust in our atmosphere.
When we leave the inner shell, we get hit again with millions of objects.
