The planet PLUTO is the 9th planet. As per our observations,
there exist further TWO giant planets beyond Pluto in the
Solar System. Of course, it is not possible to detect them
by present Optical or Radio Telescope owing to great distances
and planetary constitution. However, existence can be proved
on THREE factors. These are as below:
1. BODE-TITUS RULE OF PLANETARY DISTANCE PROGRESSION
FROM THE SUN.
2. THE HIGHEST ECCENTRICITY OF PLUTO’S ORBIT
AROUND THE SUN.
3. THE HIGH EXTREMITY OF APHELIA OF ORBIT OF THE GROUP
