<p align="justify">Trans Main-Belt Objects are small bodies whose semimajor axes are larger than those of the Main-Belt region. Majority of these objects (Trans-Neptunian Objects, Centaurs, Halley-types Comets, Jupiter Family Comets, co-orbitals), which are associated or resonating with the giant planets, have low orbital inclination (less than 70o). The e&#64256;ect of resonance that occurs on high-inclination objects (more than 70o) is not well-known. This study describes results of numerical studies in term of orbital evolution of the Trans Main-Belt objects for 10 million years that had been changed from the initial plan at 100 million years. Many objects had been thrown during the integration, so that the integration time was limited only up to 10 million years. The data consist of three categories based on their orbital parameters and 1:1 resonant objects to the giant planet. The data is taken from JPL Small Body Database (https://ssd.jpl.nasa.gov/sbdb query.cgix). Some orbital phenomena occur during the integration time of 10 million years, comprising migration objects that cause the objects show inter-changing class and be bounded in resonance with the giant planet. Resonance state examination is conducted using FAIR (Fast Identi&#64257;cation of Mean Motion Resonance) method. Through this method, some objects are known to be in state of resonance with giant planets even in a short of time span. This phenomenon indicates that high inclination objects exhibit chaotic orbits and most of them moved (be catapulted) from their initial position. Although some objects are in state of resonance with a giant planet, it does not guarantee that the orbit of the object is stable.<p align="justify"> <br />
