hi, there's something that i don't understand in the following equation:

p^2 = (4pi^2)(a^3)/G(m1+m2)

is the p a distance measured from the center of the first object to the center of the second object? or is it just the distance between them, for example a satelitte dish is 300km above the earth's surface, so would p be 300km or 300km+radius of earth?
