These calculators can be used to generate data using density, radius and gravity.
This alternate method of calculating gravity uses the solo gravity and charge field of the Earth to work out the gravity for other bodies
The calculators on this page rovolve around a single equation. That equation is rearranged in terms of the variables in it and there is a section per version of the equation. Each section contains a series of graphs that each vary one of the other variables in the equation.

Calculate the gravity given the density and radius.

g = Esr/Er+(Eed2r3)/(Ed2Er3)

Graph of gravity vs density
g = Esr/Er+(Eed2r3)/(Ed2Er3)
Gravity with changing density
Graph of gravity vs radius
g = Esr/Er+(Eed2r3)/(Ed2Er3)
Gravity with changing radius
