Nibiru's Existence Challenged - Page 4

One question on the minds of many people is: if Nibiru is indeed a real planet, is it visible to the naked eye in the night sky, and if not, when will it become visible? The answer to this question depends on two things: the physical size Nibiru, and how much light is reflected of it by its surface/atmosphere.

The optimal resolution of a human eye is about 10-20 arc seconds using visible light. Resolution is also a linear function of distance. Because the planet Uranus is just barely visible to the naked under extremely dark skies, it is used as an important "constant" in determining what the physical size of Nibiru must be in order for it to be visible right now. Below a plot is displayed showing the approximate minimum size of Nibiru for it to visible to the naked eye right now. For any planet to visible to the naked eye, it must fall into the shaded area of the graph at its given distance. Neptune and Pluto both fall below the shaded area. They are both not visible to the naked eye so this plot is generally in the right ballpark as far as naked eye visibility goes.

Because we do not see Nibiru in the naked sky, it must be smaller than approximately two earth radii. This area is represented by the darker orange area on the graph directly below Saturn. However, telescopes all over the world would have spotted Nibiru by now - after all Pluto was found 75 years ago with inferior technology. We are reaching a point where the overall size and mass of Nibiru must be very insignificant.
