We analyze observational constraints on the object C/2025 N1 (ATLAS), currently designated 3I/ATLAS, including its inferred size, mass, albedo, dust properties, and non-gravitational acceleration. Several of these characteristics are difficult to reconcile simultaneously within the standard sublimation-driven cometary model, particularly the persistence of activity at large heliocentric distances and the presence of relatively large dust grains. We investigate whether these properties can be interpreted within a framework in which internal energy-release processes contribute significantly to the evolution of Small Solar System Bodies .While an interstellar origin remains possible, we demonstrate that a Solar System origin in the Oort Cloud, followed by dynamical modification, remains a viable and testable hypothesis.This paper argues that the hyperbolic comet currently designated 3I/ATLAS is not interstellar, but instead a Solar System object whose apparent hyperbolicity arises from a non-standard, quasi-constant non-gravitational acceleration powered by internal processes within It. The results motivate further observational and theoretical studies of internal energy mechanisms in Small Bodies.
