Pluto is the least known planet within our solar system. This is simply because it is so far away - no man-made craft has ever been sent to observe it.
** It should be noted that Pluto is now considered to be a dwarf planet instead of a planet, after the 2006 ruling by the International Astronomy Union that defined what a planet is.
