An astronomical unit of measurement that is used by astrophysicists and theoretical scientists. It measures the singular gravitation at a single point in space realative to the summation of all bodies of mass that lay within pull of the specific point. The unit is based on a number of mass bodies, as the number approaches infinity, that affect the gravitation on a singular point. The unit specifies that the summation as the number approaches infinity of mass bodies lay at a distance of 1.00*10^7 km in any given direction, thus making the point of reference the center in a circle of raduis 1.00*10^7 with the outerline defined by an infinity number of masses all with mass of 1*10^20 kg.
