Of the planets which are owned by the Kepler-186, the first Earth-like planet and far from its star is Kepler-186f. Considering the order of these five discovered planets, there is a strong possibility for the existence of three new and undetected planets. Theoretically, we have recognized these three new planets locating before and after Kepler-186f. The first two new planets, orbit in the gap between Kepler-186e and Kepler-186f, and are called Kepler-186e(X1) and Kepler-186e(X2) respectively. The third planet also orbits in the exterior region of Kepler-186f is called Kepler-186f(X1). Now, after 6 years, we have reinvestigated these findings using the new information and data available.</p>}, number={1}, journal={Hyperscience International Journal}, author={Nikouravan, Bijan}, year={2021}, month={Dec.}, pages={8–12} }
