The observed anomalous acceleration in the hyperbolic trajectory of asteroid 1I/2017 U1 "Oumaumau" corresponds precisely to MOdified Newtonian Dynamics (MOND) acceleration near the Sun. This direct evidence also supports the Diffusion Gravity (DG) premise that galaxies generate additional control over their population of stars via Asymmetric Near-Field (ASNF) gravity, generated by the enormous "leverage" of galactic masses and distances, expressed through a Galactic Scaling Ratio (GSR) and the Dirac Large Number Hypothesis (LNH), which together suggest a near-field radial acceleration for stars that orbit outside the MOND radius, r(mond)=√(GM/ao), where a 0 = 1.2 x 10^-10 m/sec^2. Asteroid 1I/2017 U1 as a "test particle" demonstrated the physical mechanism of MOND, with a putative corresponding conical geometric diffusion of virtual particles between the Sun and its L1 Lagrange point with the galaxy. NASA/JPL data from that orbit of the Sun by the asteroid Il/2017 U1, shows that the anomalous acceleration observed of ~4.92 x 10^-6 m/sec^2 corresponds to a constant MOND acceleration applied to the asteroid in its hyperbolic trajectory approach asymptote, resulting in a modified departure asymptote from the Sun. This evidence suggests that the additional "leverage" of ASNF gravity may be the common element in MOND constant velocity rotation curves of galaxies. The results also confirm a galactic L1 point location for our Sun is likely ~4 x 10^10 meters (40M km) from the Sun in the direction of the Milky Way galactic center, and inside the perihelion of planet Mercury (46M km).
