It has been steered by simulations that there could also be an Earth-sized planet lurking on the fringe of the photo voltaic system. This planet, if it exists, can be situated past the identified planets and would have an analogous dimension to Earth. The invention of such a planet would have vital implications for our understanding of the photo voltaic system and its formation. If this planet does exist, it will problem present theories and fashions of the photo voltaic system, in addition to elevate questions on the way it fashioned and why it’s situated in such a distant area of the photo voltaic system. Additional analysis and observational information are wanted to substantiate the existence of this potential planet and higher perceive its properties.
