From the article, the object "is currently around three billion kilometres from the Sun. It will reach its closest point, known as perihelion, in 2031. At that time, it will be positioned below the plane of the solar system, near the orbit of Saturn." Given how far away it currently is, I'm wondering how accurately the trajectory can be modeled, and how the larger planets (like Saturn) may affect that path? I would guess there are apps where I could test and adjust comet trajectories but I've yet to learn about whats out there.
