Several new Trans-Neptunian Object (TNO) have been found orbiting the Sun with very eccentric orbits. Here we investigate the evolution of the orbit of three new found TNOs (2022 HB5, 2022 AZ9, and 2018 AD39) through numerical simulation. We found that 2022 HB5 and 2022 AZ9 are very unstable while 2018 AD39 has stable orbit. Furthermore, we investigate the influence of Planet-Nine into their orbital evolution. It shows that the existence of Planet-Nine changes the orbital evolution of the TNOs, except 2018 AD39.
