It's questionable whether Zoozve should be listed as a satellite of Venus. It actually orbits the Sun in a 1:1 orbital resonance with Venus. There are many other quasi-satellites that should be added if Zoozve is added. Then there are all the Trojan asteroids, which are also in 1:1 orbital resonances with Jupiter or other planets.

@matthewtiscareno Thank you for your comments, Matthew! I can see your point. Do we think users expect Zoove, or other quasi-satellites, to be there when searching the system? I'm not sure I know the answer to that, but if it's not a user expectation then that's more reason to not include them.

I don't think so. Zoozve's average distance to Venus is 0.2 AU. It's a Sun-orbiting object, not part of the Venus system.

Just removed Zoove, and added Saturn and Jupiter systems.
