Target nodes keep spinning.

[Space boy]

I am trying to get a kerbin encounter and I managed to get a 148,000 km separation from kerbins SOI, so I thought, "great, now it will be very easy!" Boy was I wrong, I tried to get a final encounter, but the target nodes keep spinning around my solar orbit and I am not able to get an encounter. I am currently not in a kerbin transfer window (thats what it looks like) so I really need help.

This isn't what I imagined, and it seems like you still do not understand how Hoffman transfer works.

Basically, because your orbits are too close, the accuracy of interception position becomes veeeery low.

Try to learn how to do interplanetary transfers, or you can consider seeing how mechjeb does it.

Did you cheat your way into orbit?

Yes, you are encountering floating point errors with the calculations.

Best bet would be to pick a point and set a maneuver node and prep a burn.

Nope, I got into the orbit by myself.

What do I do now???

I've got about 1100m/s left.

Make a maneuver node in front of your ship, try sliding prograde, retrograde, radial out and radial in, in turn and slowly (less than 1 m/s at the time), keeping track of distance markers. One of them should start reducing distance to Kerbin

Hey, thanks man, you reminded me of the Hoffman transfer and I was able to get back. I was getting Apollo 13 vibes really.

What I did basically was increase my Apoapsis just a little high above kerbins orbit and then time-warped there and started reducing my periapsis to just to kerbins orbit and I got an encounter as the target nodes were closing in.

It's actually called a Hohmann transfer.

Hey, I see you are a moderator, can you like close this thread or something cause the problem is solved. I don't expect anymore replies now.

But if I did that, nobody else would be able to chime in with little pedantic points. 

On a more serious note, it is not generally our practice to close such threads.  We allow them to gracefully live out their existence as they sink lower and lower in the list.  Sometimes they spark further discussion of details or subtleties that were not previously considered in the thread.

You can upvote one or more of the answers, though.  And, as the Original Poster of the thread, you can mark a specific post as the correct answer if you choose.  This will show the question as answered in the list of Gameplay Questions.

So, what do we discuss now? Space Force?

Okay, I have marked the answer which solved 'my' problem, but there are also answers which may be useful for others in other situations so I think yeah this thread should live on.
