Abstract

In 2015, after the discovery of Kepler-186f, the fifth exoplanet in orbit of its star, Kepler-186, we investigated for three new undetected planets in the Kepler-186 system [1]. 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.
