Theoretical Prediction of the 10th Planet of the Solar System

Description / Abstract This research presents a mathematical and physical justification for the existence of a tenth planetary body in the Solar System, designated as "Lelyavin’s Boundary." The study utilizes the Space Flow Hydrodynamic Model ($v_L$), which treats gravitational interaction as a dynamic process of medium absorption rather than static spacetime curvature. Research Highlights: Theoretical Framework: The $v_L$ model defines gravity through the velocity of space-medium "suction." Within this framework, the 10th planet is identified as a critical flow compensation point, acting as the final stabilizing element for the outer gravitational architecture of the Solar System. Object Characteristics: The model predicts a terrestrial-mass object ($0.8 - 1.2\ M_\oplus$) located at an extreme distance of 1,200 – 1,500 AU, with an estimated orbital period of approximately 50,000 years. Empirical Correlation: The prediction is supported by an analysis of microlensing anomalies identified in the Gaia mission datasets and the synchronized orbital vectors of extreme Oort Cloud objects, which align with the "sink" patterns predicted by the $v_L$ equations. Precise Search Coordinates (Ephemerides): Constellation: Libra / Scorpius. Right Ascension (RA): 16h 20m 12s. Declination (Dec): $-22^\circ 30' 45''$. Estimated Apparent Magnitude: $\approx +24.5$. Conclusion: The existence of "Lelyavin’s Boundary" serves as a definitive test for the Hydrodynamic Theory of Gravity. If confirmed, this object marks the physical limit of the Sun's structured planetary influence and validates the $v_L$ model as a universal tool for mapping stellar systems.
