The Jupiter Trojans, commonly called trojan asteroids or simply trojans, are a large group of asteroids that share the planet Jupiter's orbit around the Sun.

Jupiter did not sweep up all the debris in its own orbit. That was news to me. There are patches of material about a quarter the ellipse before and behind, traveling the same path. How?

Saturn and Mercury are the only two planets that do not have Trojans. Laplace's "Great Inequality": the near-5:2 resonance between Jupiter and Saturn prevent this. That must be some strange math; never heard of that myself.

Still even earth has stones moving in a stable path ahead of us and behind. We do?!?

Why have we not visited those or the ones around Venus? They both lie in the Goldilocks zone. Maybe one has water and life? Too small? Tell that to the frozen water in the impact craters of superheated Mercury. Something that also should not exist and it does.

Right, right...the kids are more interested in swiping left and right on hand held screens. Age of Shoddy can't end too soon.
