Unveiling the Enigmatic Nature of Planet 9: Could Modified Gravity Hold the Key?

Astronomers have proposed that Modified Newtonian Dynamics (MOND) theory, which has been successful in understanding galactic rotation, could explain the strange orbital paths of Kuiper Belt Objects (KBOs) that have led to speculation about the existence of Planet 9. MOND suggests that the gravitational pull of the galactic core affects the orbital mechanics of objects farther away from the Sun, aligning their major and minor axes towards the core. While the absence of direct evidence for Planet 9 may eventually become evidence of its absence, the study highlights the need for further observations and a deeper understanding of gravitational physics to unravel the mysteries of our universe.
