How the standard gravitational parameter works
In short: The standard gravitational parameter is the product of a celestial body's mass and the gravitational constant.
1. The standard gravitational parameter μ of a celestial body is the product of the gravitational constant G and the mass M. 2. This approximation is standard for planets orbiting the Sun or most moons and greatly simplifies equations. 3. Thus only the product of G and M is needed to predict the motion of the smaller body. 4. Orbits can be measured with great precision and used to determine μ with similar precision.
