I think some of the L points are gravity "hills" instead of "wells", so they are unstable. The wells will trap things. If you put something into orbit around a gravity hill, they have to actually orbit around the hill.

I thought they covered 2010 TK7 and Cruithne (not a trojan but promoted as Earth's second moon for a while) before, at least in their Deep Sky video series, but I'm not seeing it... And not under tdarnell's videos either...

Meanwhile, I didn't think this would get in the top 15 let alone the top 5... I figured it would Sift though...

In 2010, we discovered our first (and only) trojan asteroid for sun-earth at L4. I'm surprised the video didn't mention it.
