Looks like it almost collides with Jupiter and Uranus. Why wouldn’t its gravity have affected their orbits when it flew so close to them?
Different solar system. It can stay there, too.
It’s a comparison overlay to show what the orbit would look like in our solar system. The exoplanet is not in our solar system.
Because Jupiter and Neptune are in our solo at system.
The weird planet is in another system. It might be showing our solar system as a comparison of what it is doing in the other system. Out there, it might be affecting the orbits of other bodies in its system. Unless it is widely out of the ecliptic of any other planets. Like Pluto is in ours.
