Dear Group,

I am hoping for a math genius to help me with a certain problem. Now, I am not that advanced in mathematics at all and only know certain very basic things, and I hope that the following problem is quite simple, or that the solution can be relayed to me in simple terms if there is one.

I am trying to model a gravitational field (acceleration values) about a celestial body that does NOT extend away from the centre of the body in accordance with a general inverse square law.

Now, in astronomy, I am aware that on the issue of deriving the curvature of an elliptical body in orbit, of say the sun, you only need 3 points, and that a unique curve will pass through all 3 points to give the total ellipse. I am hoping for something similar by way of a solution to my problem.

I have 3 distance measures from the centre of an ‘experimental’ celestial body, with the centripetal gravitational values at those points. What I want to know is, is there a way to determine the unique curvature of the field from just this data? I am hoping for a general method so I could experiment with different values. Any help would be appreciated.

Distance from centre of body = 238857.528 Miles

Centripetal (Gravity) Acceleration = 0.000000020633339375 Miles/Second^2

Distance from centre of body = 1114.118548 Miles

Centripetal (Gravity) Acceleration = 0.0009483872877 Miles/Second^2

Distance from centre of body = 1079.943132 Miles

Centripetal (Gravity) Acceleration = 0.006093296399 Miles/Second^2

Sincerely

Keith
