Here's a simulation of the theorized planet that's been making the news lately.

Welcome back Kevin!  It's been a while.

Thanks for that.  Here's all the objects in your list simulated in the new browser version of Gravity Simulator.  Some extend far out and the new version has a hyperbolic trail bug that you'll notice if you zoom out enough to see their entire orbits.

This one has background stars, so you tell which way you're pointing.

You can use the slider controls to change the viewing perspective.

If you need help making a graphic, let me know.  The new version lets me do animated flybys too, either save as GIF or youTube.
