I was speaking of Newton's law of universal gravitation. Not sure where I got third law from when I wrote that earlier.
This article talks about it:

"It encapsulates the idea that all the particles of matter in the universe attract each other through the force of gravity – Newton's law tells us how strong that attraction is. The equation says that the force (F) between two objects is proportional to the product of their masses (m1 and m2), divided by the square of the distance between them. The remaining term in the equation, G, is the gravitational constant, which has to be measured by experiment and, as of 2007, US scientists have measured it at 6.693 × 10−11cubic metres per kilogram second squared."
I was just wondering aloud about how a model could mimic the earth's gravitational pull up to a certain point before the earth's pull overcomes it.
More or less ramblings. But, basically, a hemisphere 200 miles in diameter would feel earth-like up to a certain distance and it would be interesting how It's characteristics mimic earth up until fail point .
