Pluto’s orbital Period

Pluto’s orbital Period

Using the formula P=sqrt((4pi2r3)/(G(msun+mplanet)) which was derived
from Kepler’s planetary laws, and using a value of 0.000000000066662
for the gravitational constant G we get the following differences (in
days) between the observed (in the case of Pluto predicted) and
calculated orbital periods:

MERCURY -0.0059718
VENUS -0.0106276
EARTH 0.0176480
MARS 0.1362043
JUPITER -1.6316242
SATURN 0.4371626
URANUS 1.3049705
NEPTUNE 1.8850109
PLUTO -285.4581278

The value of G used produces a difference of between -2 and +2 days
for the first 8 planets, sufficient to prove Kepler and Cavendish
correct. In the case of Pluto the difference of -285 days suggests
that one or more of the predicted orbital period (247.7years) or mass
or mean distance from the sun are wrong.
