Comet 2P/Encke has been known as a short periodic, low inclination, and relatively close orbit comet. These properties convinced us to put Comet 2P/Encke as part of the Near-Earth Comets (NEC) which has a high possibility of a close encounter with Earth and another Terrestrial planet. Although the Comet 2P/Encke already found in hundred years ago, based on the present orbit, the origin of Comet 2P/Encke still unable to be known precisely. Several studies have tried to simulate, but there is still no certainty about dynamical process responsible for the real orbit of comet 2P/Encke. <br /> <br /> This study aims to examine the origin of Comet 2P/Encke by taking the Trans-Neptunian (The Kuiper belt) as an initial hypothesis, to review the dynamical process and interactions with the planets in the Solar system, and to analyse the possible physical activity of comet 2P/Encke based on orbit integration. For numerical integration, we used thousands of artificial object in the Kuiper belt for hundreds of millions of years with the involvement of Jovian and Terrestrial planets in the Solar System. We generated our numerical process gradually from Trans-Neptunian, Hill-Sphere Neptune, and the area at a distance of less than 4 au. <br /> <br /> We obtain the result as 1 of 8400 particles that reach the similar orbit with comet 2P/Encke in time t ~9.97x107 years or t ~1.7x105 years after the visible time (equivalent to ~26740 times perihelion passages). This result exceeded the probability of physical age of comet to remain in the active state. Thus it is doubtful comet 2P/Encke remains active during this period. We also obtain interactions between the particle with the Jovian planets and the Terrestrial planets that makes particle achieved a similar orbit of comet 2P/Encke.
