It's said to orbit the sun every 10000 to 20000 Earth years. Jupiter takes almost 12 Earth years to orbit the sun. Jupiter would have intercepted it before we do, unless the people change the orbital plane in some snowflake angle where it's near perpendicular to the other planets.

Looking up all the various hypothetical paths of orbit clearly shows it would take forever. Even taking into account the movement of all the planets and Kepler's 2nd law of planetary motion

Looking up these images was funny.

I can't think of any around other stars. I looked it up and only found one planet. The image WASP 79-b is an artist's impression.

I know the planets aren't completely level with each other. I think it was Neptune that was slightly off. Pluto is greatly inclined, but still not close to being in a perpendicular orbit from the rest.

Examining exoplanets is tedious work, so there is likely a lot of nearby planets that still haven't been observed. Many of them are detected but not observed by observing the stars. Gravity of planets tugs on stars as they orbit around it, so any movement of that star shows something is pulling on it. You can't really do this work on Earth because the atmosphere makes stars twinkle as their light passes through gas layers.

The photos we do have are of stars with the star blocked out so the camera only sees around it without getting overexposed. Then any planet near it will reflect or block light. Some photos don't need to block the star, they instead look for a shadow passing in front of the star.

So depending on how the planet orbits its star in relation to its angle from Earth may mean it will pretty much be invisible to us. Trying to find moving over the stars behind it would be near impossible. Even passing its parent star may show a light difference of less than 0.1% for a small planet or a far away planet. A lot to astronomy is speculative.

The good thing about these planets passing their star is the light passing through their atmosphere if it has one. The wavelength of the light compared to the wavelength of the star's light can give us a strong estimate as to what elements make up the chemical composition of the atmosphere.
