That seemed a simple enough question that David posed...at 0.01 Solar masses it should be quite bright even at 190 AU. Even Jupiter at 0.001 solar masses, would be magnitude 12-13 at that distance. How it could be at the limit of a 16" telescope + CCD camera beats me. This would indicate something closer to earth size.
I also I see one of the most experienced amateur astronomers on this list (David Higgins) being told off for challenging this claim and giving good reasons.....come on guys !
