Newton's G has nothing to do with gravity... it is a compound value. composed of spherical constants, pi and the scaling factor of magnetism
It is a "matter" constant... related to the "mass of a spherical body"
and NOTHING to do with gravity....
Gravity is to do with FIELD spin.... which is driven from afar.................
Yes weird hey... but its true
Earthlings have gone light years off the mark in so many important scientific concepts.

well in effect all the spin systems of the Universe are linked like cogs, one driving the other... there are drivers and there are those that are driven
Mach twigged to this quite a while ago... see Mach's principle
but I suppose all are drivers and all are driven, all spins are governed by energy considerations
eg the Sun drives the Earth... the Earth drives the Moon... the galactic spin drives the Sun.... and Jupiter drives the Sun to some degree... what a tangled spinning web!!!
all understandable... but space travelers are going to have to map out the spin zones if they wish to go where no earthling has gone before AND be able to come back, LOL
Now I know g = (G M1*M2)/r^2 Newton
but really g = (Gcentral-spin) / r^2.... ie spin / r^2... or an acceleration resultant towards the centre of spin.
so since the mass of the Earth or whatever cosmic body you wish to point to, is NOT really known...... and, as if you know the mass of the Sun... this is shabby science
to point to mass to generate gravity is totally totally SILLY
so from the above
IF you knew G with certainty... (and G's value is NOT the value published, BTW close but incorrect)
then you may find cosmic mass from Gcentral-spin = G * cosmic Mass
but to use cosmic mass in any equation is just so inaccurate
Cosmic mass is the superposition of all charged and magnetic particles in a spherical body.... mmmh, just a bit hard to play with, LOL
