comment At what distance from Earth would our Sun be the same apparent magnitude as the next brightest star in the sky?
Different question entirely, but the distance is the thing of note. Moving in a direction that isn't directly towards the object would just change the distance formula.

comment Why hasn't the “9th Planet” been detected already?
The current dominance of the Sun might extend half-way to the nearest star now, but statistically we come close to other stars frequently, maybe a light year or closer, which could easily mean that any far out object would no longer be orbiting, depending on how close of a pass.

Yea, the chart isn't perfect. Mars shows up as further than Jupiter, for instance. That should be the case, and I don't think all of the planets are quite in the right area...
