The Value of heliocentric G

The Value of heliocentric G

Using the formula P=sqrt((4pi2r3)/(G(msun+mplanet)) which was derived
from Kepler’s third law, the value of the universal constant G can be
tested. If we use G=6.673E-11, we get the following differences (in
days) between observed (in Pluto’s case predicted) and calculated
orbital periods:

MERCURY 0.0360901
VENUS 0.0968106
EARTH 0.1922924
MARS 0.4646257
JUPITER 0.4408873
SATURN 5.5815260
URANUS 15.9874062
NEPTUNE 30.6686351
PLUTO -242.0601381

If however we use G=6.6676E-11 we get the following differences:

MERCURY 0.0004931
VENUS 0.0058855
EARTH 0.0444906
MARS 0.1866821
JUPITER -1.3130826
SATURN 1.2278426
URANUS 3.5616361
NEPTUNE 6.3090054
PLUTO -278.7879300

If however we use G=6.66662E-11 we get the following differences:

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
