Have you had a close encounter with debris (close encounter for this is within 5km)?

[Ziggy Kerman]

I've had a space station up in orbit, the inclination is the same as Woomerang, and I had a replica Delta IV Heavy DCSS wizz past during docking procedures, warranting a Class 3 warning and debris avoidance maneuver being planned. I have 6 classes of possible collision, these are the classes and distances and the avoidance, along with the main culprits (if there's any needed, looking at you 4 and 5):
Class 0-The dreaded one-10m-500m- say your final prayers, these are gonners.- Odd kick stage action

Class 1-Most likely Collision- Within 500m if active craft- If craft A (collider) is active, preform avoidance of craft B (Collidee) to make it a class 2 warning, visa versa if craft A isn't active.-Stray 2nd stage after decouple

Class 2- Maybe?-500m-1.5km- If the thing doesn't have a stupidly large wingspan, orient the panels in a perpendicular direction to the path-Random FlatSat or Cubesat

Class 3-Probably not happening-1.5km-2km- At this point I can't easily flip flop between them, and if it's a ways away during that build up, I just give the RCS a little puff-Random second stage on the same plane or crossing planes at same time

Class 4-At this point it might as well not be a warning-2km-5km-I just make sure I don't enter in to 3 below during any operations.- Dead and ejected space station module if it's both space station bits

Class 5-Who cares-5km-Ad infinitum- keep going, doesn't really need to do anything-Dres

With debris? Don't think so. But I had like ~200m close encounter with my own space station when I was chasing an asteroid.

When I first started playing ksp, I ignored debris, until I almost slammed Val through an old used upper stage.

 

Afterthat, I clean all debris by deorbiting it to burn up, or if I can't, I hit the terminate button.

All the more reason to either a) add deorbit in motors to the top of your launch rocket’s insertion stage (whether that’s a single stage with boosters or a multi stage setup) to push it out of orbit once it’s empty; b) build controllable boosters that can fly back down under their own power to either be recovered or just dropped in the sea/burnt up; or c) turn the persistent debris setting down to zero so that debris is automatically deleted. Personally I prefer to either build the launch rocket to have slightly too little delta-V to get all the way to orbit so that it will naturally fall back down while the payload itself does the last little bit of insertion burn, or build a launch rocket that can be returned and recovered to be “reused” later.

Ditto.

Esp since I like standard launchers and normally use MJ to handle the ascent to orbit.

Which gives a scary high possibility of smacking into to spent stages or other debris.

My closest encounter wasn't 5km, it was more like < 50m ...

I had a space station where the 2nd stages were the main propulsion unit until docking and then I ejected it, I had to do some odd RCS maneuvering to get it away because I forgot my deorbit motors, well, at this point it's only a matter of time until I have a strike with a station with a capulse trunk or SM piece that got blown off before the deorbit burn.

My Hermes coms system is unnumbered, for some reason, so I'm fairly weary of debris termination, so I'm working on Allen, the Alligator; a giant BFR-esque thing with the Mk3 tail thingy to catch dead satellites or a MEPs to do, what is says on the tin.
