The ones that are orbiting along the horizon are from Mün missions. The vertical orbits are from just being bored and orbiting or a couple deployed satellites. However, I only have three on the Mün right now because they glitch into the ground and I can\'t do anything about it. That and the ones that I do attempt to bring back have either (in most cases) made it back or in orbit of Kerbin. :C Also, that debris that is far off is orbiting Kerbin was from a mission to the Mün and actually orbits Kerbin in an elliptical orbit, gets into the Mün\'s SOI and gets launched back to Kearth. I can tell because I\'ve actually witnessed it three times and every once and a while when I\'m doing a mission I look at my map view and sometimes the orbit is a bit more vertical and a tad bit more elliptical every time it exits the Mün\'s SOI.
