The announcement of the exomoon candidate Kepler-1625 b-I changed how we see satellite systems. Because of its unusual physical characteristics, there are many questions about the stability and origin of this body. Currently, we have enough theoretical studies to assure that if Kepler-1625 b-I is confirmed, it would be stable. Previous works indicated that the most likely scenario for the origin of this satellite is capture, even though in situ formation was also proved to be possible. Recently, signs for a second exomoon, Kepler-1708 b-I, were published, and much like Kepler-1625 b-I, its characteristics are nothing like we have in our Solar System. In this seminar, we explore the dynamics of exomoon candidates and the likeability of systems with multiple planet-like exomoons.
